1、部署分离的LAMP，部署到二台服务器上，PHP加载xcache模块
首先准备LAMP环境，准备两台linux主机，一台是192.168.0.10 ，这台上面主要跑apache httpd ，mariadb数据库，另外一台是192.168.0.30 ，这台上面跑PHP-fpm;
1)在192.168.0.10这台主机上安装httpd和mariadb ，这个安装可以yum安装，也可以编译安装。我这里就yum安装来演示

4）配置PHP-fpm工作在192.168.0.30的9000端口
[root@test-centos7-node3 ~]# rpm -ql PHP-fpm/etc/logrotate.d/PHP-fpm/etc/PHP-fpm.conf/etc/PHP-fpm.d/etc/PHP-fpm.d/www.conf/etc/sysconfig/PHP-fpm/run/PHP-fpm/usr/lib/systemd/system/PHP-fpm.service/usr/lib/tmpfiles.d/PHP-fpm.conf/usr/sbin/PHP-fpm/usr/share/doc/PHP-fpm-5.4.16/usr/share/doc/PHP-fpm-5.4.16/fpm_liCENSE/usr/share/doc/PHP-fpm-5.4.16/PHP-fpm.conf.default/usr/share/fpm/usr/share/fpm/status.HTML/usr/share/man/man8/PHP-fpm.8.gz/var/log/PHP-fpm[root@test-centos7-node3 ~]# grep -i "Listen" /etc/PHP-fpm.d/www.conf; 'ip.add.re.ss:port' - to Listen on a TCP socket to a specific address on; 'port' - to Listen on a TCP socket to all addresses on a; '/path/to/unix/socket' - to Listen on a unix socket.#Listen = 127.0.0.1:9000Listen = 192.168.0.30:9000; Set Listen(2) backlog.

5）启动PHP-fpm
[root@test-centos7-node3 ~]# systemctl start PHP-fpm[root@test-centos7-node3 ~]# ss -ntlState Recv-Q Send-Q Local Address:Port Peer Address:Port ListEN 0 128 *:22 *:* ListEN 0 100 127.0.0.1:25 *:* ListEN 0 128 192.168.0.30:9000 *:* ListEN 0 128 :::22 :::* ListEN 0 100 ::1:25 :::* [root@test-centos7-node3 ~]#
提示：可以看到PHP-fpm启动起来了，并且监听在192.168.0.30的9000端口上，接下来我们配置httpd，请求.PHP结尾的资源都交给192.168.0.30：9000执行
6）配置httpd的请求.PHP的资源能够连接至192.168.0.30：9000
[root@test-centos7-node1 ~]# httpd -M |grep fcgiAH00558: httpd: Could not reliably determine the server's fully qualifIEd domain name,using fe80::20c:29ff:fef2:820c.

提示：如果没有加载proxy_fcgi_module需要先加载此模块，然后才能够代理fcgi协议
7）在192.168.0.30上新建一个PHP测试页面，然后访问192.168.0.10/teset.PHP，如果能够将测试页面解析出来，说明httpd和PHP-fpm是连接正常的
[root@test-centos7-node3 ~]# ip a s ens33 2: ens33: <broADCAST,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000 link/ether 00:0c:29:4a:bd:74 brd ff:ff:ff:ff:ff:ff inet 192.168.0.30/24 brd 192.168.0.255 scope global ens33 valID_lft forever preferred_lft forever inet6 fe80::20c:29ff:fe4a:bd74/64 scope link valID_lft forever preferred_lft forever[root@test-centos7-node3 ~]# ll /var/www/HTMLls: cannot access /var/www/HTML: No such file or directory[root@test-centos7-node3 ~]# mkdir /var/www/HTML -p [root@test-centos7-node3 ~]# cat > /var/www/HTML/test.PHP <?PHPPHPinfo();?>^C[root@test-centos7-node3 ~]# cat /var/www/HTML/test.PHP <?PHPPHPinfo();?>[root@test-centos7-node3 ~]#
8）重新启动httpd，然后访问192.168.10/test.PHP
[root@test-centos7-node1 ~]# systemctl restart httpd[root@test-centos7-node1 ~]# curl -I http://192.168.0.10/test.PHPhttp/1.1 200 OKDate: Mon,27 Jan 2020 12:54:56 GMTServer: Apache/2.4.6 (CentOS)X-Powered-By: PHP/5.4.16Content-Type: text/HTML; charset=UTF-8[root@test-centos7-node1 ~]#
提示：到此LAP环境已经搭建好了，但是PHP-fpm是不支持xcode的，接下来我们来安装xcache模块
9）安装xcache模块

提示：当然xcache这个模块我们可以编译安装。
10）重启PHP-fpm，然后访问测试页，看看是不是支持xcache
[root@test-centos7-node3 ~]# systemctl restart PHP-fpm[root@test-centos7-node3 ~]#
提示：通过访问测试页面，我们看到了PHP-fpm支持了xcache,到此PHP部分就搭建完毕了，接下来我们要来利用PHP连接数据库
11)安装PHP-MysqL 此包用于PHP连接MysqL数据库
[root@test-centos7-node3 ~]# yum install -y PHP-MysqLLoaded plugins: fastestmirrorLoading mirror speeds from cached hostfile * base: mirrors.163.com * extras: mirrors.163.com * updates: mirrors.aliyun.comResolving DependencIEs--> Running transaction check---> Package PHP-MysqL.x86_64 0:5.4.16-46.1.el7_7 will be installed--> Processing Dependency: PHP-pdo(x86-64) = 5.4.16-46.1.el7_7 for package: PHP-MysqL-5.4.16-46.1.el7_7.x86_64--> Running transaction check---> Package PHP-pdo.x86_64 0:5.4.16-46.1.el7_7 will be installed--> Finished Dependency ResolutionDependencIEs Resolved========================================================================================== Package Arch Version Repository Size==========================================================================================Installing: PHP-MysqL x86_64 5.4.16-46.1.el7_7 updates 101 kInstalling for dependencIEs: PHP-pdo x86_64 5.4.16-46.1.el7_7 updates 99 kTransaction Summary==========================================================================================Install 1 Package (+1 Dependent package)Total download size: 201 kInstalled size: 424 kDownloading packages:(1/2): PHP-MysqL-5.4.16-46.1.el7_7.x86_64.rpm | 101 kB 00:00:00 (2/2): PHP-pdo-5.4.16-46.1.el7_7.x86_64.rpm | 99 kB 00:00:00 ------------------------------------------------------------------------------------------Total 513 kB/s | 201 kB 00:00:00 Running transaction checkRunning transaction testTransaction test succeededRunning transaction Installing : PHP-pdo-5.4.16-46.1.el7_7.x86_64 1/2 Installing : PHP-MysqL-5.4.16-46.1.el7_7.x86_64 2/2 Verifying : PHP-MysqL-5.4.16-46.1.el7_7.x86_64 1/2 Verifying : PHP-pdo-5.4.16-46.1.el7_7.x86_64 2/2 Installed: PHP-MysqL.x86_64 0:5.4.16-46.1.el7_7 Dependency Installed: PHP-pdo.x86_64 0:5.4.16-46.1.el7_7 Complete![root@test-centos7-node3 ~]#
12）在192.168.0.10的mariadb数据库里添加一个帐号，用于PHP测试连接数据库用
[root@test-centos7-node1 ~]# MysqLWelcome to the MariaDB monitor. Commands end with ; or \g.Your MariaDB connection ID is 4Server version: 5.5.56-MariaDB MariaDB Servercopyright (c) 2000,MariaDB Corporation Ab and others.Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.MariaDB [(none)]> grant all on *.* to 'PHP_test'@'192.168.0.%' IDentifIEd by 'admin';query OK,0 rows affected (0.00 sec)MariaDB [(none)]> flush privileges;query OK,0 rows affected (0.00 sec)MariaDB [(none)]> \qBye[root@test-centos7-node1 ~]#
13）在PHP-fpm服务器上添加一个测试页，用于测试PHP-fpm是否能够连接数据库
[root@test-centos7-node3 HTML]# pwd/var/www/HTML[root@test-centos7-node3 HTML]# lltotal 8-rw-r--r-- 1 root root 159 Feb 14 07:21 test_conn_MysqL.PHP-rw-r--r-- 1 root root 20 Feb 14 06:40 test.PHP[root@test-centos7-node3 HTML]# cat test_conn_MysqL.PHP <?PHP$MysqLi=new MysqLi("192.168.0.10","PHP_test","admin");if(MysqLi_connect_errno()){echo "Failure";$MysqLi=null;exit;}echo "OK\n";$MysqLi->close();?>[root@test-centos7-node3 HTML]# 14）重启PHP-fpm，然后再访问http://192.168.0.10/test_conn_MysqL.PHP
[root@test-centos7-node3 HTML]# curl http://192.168.0.10/test_conn_MysqL.PHPOK[root@test-centos7-node3 HTML]#
提示：可以看到我们访问测试连接数据库的脚本文件能够正常连接到数据库，到此LAMP的环境就搭建完毕了。
2、部署wordpress论坛，并实现正常访问登录论坛。
1）下载wordpress源码包，然后把源码放到我们刚才搭建的LAMP环境中。
[root@test-centos7-node1 ~]# ip a s ens332: ens33: <broADCAST,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000 link/ether 00:0c:29:f2:82:0c brd ff:ff:ff:ff:ff:ff inet 192.168.0.10/24 brd 192.168.0.255 scope global ens33 valID_lft forever preferred_lft forever inet6 fe80::20c:29ff:fef2:820c/64 scope link valID_lft forever preferred_lft forever[root@test-centos7-node1 ~]# cd /var/www/HTML/[root@test-centos7-node1 HTML]# ls[root@test-centos7-node1 HTML]# rzrz waiting to receive. zmodem trl+C ȡ 100% 7989 KB 7989 KB/s 00:00:01 0 Errorstar.gz...Transferring wordpress-4.5.1-zh_CN.tar.gz...[root@test-centos7-node1 HTML]# lswordpress-4.5.1-zh_CN.tar.gz[root@test-centos7-node1 HTML]# tar xf wordpress-4.5.1-zh_CN.tar.gz [root@test-centos7-node1 HTML]#
提示：在192.168.0.10上放一份源码的原因是httpd的静态页面是不会往后面的PHP-fpm服务器转的，所以我们放程序源码除了httpd上要放一份外，PHP-fpm服务器上也要放一份
[root@test-centos7-node3 ~]# ip a s ens332: ens33: <broADCAST,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000 link/ether 00:0c:29:4a:bd:74 brd ff:ff:ff:ff:ff:ff inet 192.168.0.30/24 brd 192.168.0.255 scope global ens33 valID_lft forever preferred_lft forever inet6 fe80::20c:29ff:fe4a:bd74/64 scope link valID_lft forever preferred_lft forever[root@test-centos7-node3 ~]# cd /var/www/HTML/[root@test-centos7-node3 HTML]# lspdo.PHP test_conn_MysqL.PHP test.PHP[root@test-centos7-node3 HTML]# rm -rf *[root@test-centos7-node3 HTML]# ls[root@test-centos7-node3 HTML]# rzrz waiting to receive. zmodem trl+C ȡ 100% 7989 KB 7989 KB/s 00:00:01 0 Errorstar.gz...[root@test-centos7-node3 HTML]# tar xf wordpress-4.5.1-zh_CN.tar.gz [root@test-centos7-node3 HTML]# lswordpress wordpress-4.5.1-zh_CN.tar.gz[root@test-centos7-node3 HTML]#
提示：放好源码文件后，我们要在数据库里创建一个库来存放WordPress程序的数据
2）在数据库里创建一个数据库用于存放wordpress的各种数据
[root@test-centos7-node1 HTML]# MysqLWelcome to the MariaDB monitor. Commands end with ; or \g.Your MariaDB connection ID is 36Server version: 5.5.56-MariaDB MariaDB Servercopyright (c) 2000,MariaDB Corporation Ab and others.Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.MariaDB [(none)]> show databases;+--------------------+| Database |+--------------------+| information_schema || MysqL || performance_schema || test |+--------------------+4 rows in set (0.00 sec)MariaDB [(none)]> create database wordpress;query OK,1 row affected (0.00 sec)MariaDB [(none)]> grant all on wordpress.* to wordpress@'192.168.0.%' IDentifIEd by 'admin';query OK,0 rows affected (0.01 sec)MariaDB [(none)]> \qBye[root@test-centos7-node1 HTML]#
提示：为了安全，我们在数据库里专门创建了一个用户用于WordPress程序连接数据库用
接下来我们就可以通过浏览器来安装WordPress
提示：它提示不能写入wp-config.php，我们需要对httpd运行的用户来进行授权，让其对wordpress目录有写 *** 作即可
[root@test-centos7-node3 HTML]# setfacl -R -m u:apache:rwx wordpress [root@test-centos7-node3 HTML]# getfacl wordpress# file: wordpress# owner: nobody# group: 65534user::rwxuser:apache:rwxgroup::r-xmask::rwxother::r-x[root@test-centos7-node3 HTML]#
提示：我们授权其实在PHP-fpm上面授权即可。授权后我们就可以刷新刚才的安装页面，进行安装
到此wordpress就搭建完毕了，后续就可以通过以上界面管理wordpress
3、收集apache访问日志，并实现图形化展示。
首先说一下实现过程吧，要想图形化展示日志，我们可以利用rsyslog的前端展示工具loganalyzer来展示。用这个工具它是基于LAMP架构来实现的，在这之前我们先把apache的访问日志交给rsyslog，rsyslog再把对应的日志写到数据库里，然后通过日志展示工具loganalyzer去数据库把日志对出来，然后展示出来。
1）配置httpd的日志，把错误日志传给syslog:local1，把访问日志通过管道传给logger，然后logger再把它传给 local2
[root@test-centos7-node1 ~]# grep -E "^Error" /etc/httpd/conf/httpd.confErrorLog syslog:local1[root@test-centos7-node1 ~]# grep -E "^[[:space:]]*CustomLog" /etc/httpd/conf/httpd.conf CustomLog "|/usr/bin/logger -p local2.info" combined[root@test-centos7-node1 ~]#
提示：以上配置就是把httpd的访问日志传给local1 ，把访问日志传给local2，local1和local2是rsyslog的自定义日志设施
2）安装rsyslog-MysqL，这个包主要是用于rsyslog连接数据库的一个模块，除此以外还有一个创建数据库和表的sql脚本，用此脚本可以创建存放日志的库和表
[root@test-centos7-node1 ~]# yum install -y rsyslog-MysqLLoaded plugins: fastestmirrorLoading mirror speeds from cached hostfileResolving DependencIEs--> Running transaction check---> Package rsyslog-MysqL.x86_64 0:8.24.0-12.el7 will be installed--> Finished Dependency ResolutionDependencIEs Resolved================================================================================================================================== Package Arch Version Repository Size==================================================================================================================================Installing: rsyslog-MysqL x86_64 8.24.0-12.el7 my_base 35 kTransaction Summary==================================================================================================================================Install 1 PackageTotal download size: 35 kInstalled size: 20 kDownloading packages:rsyslog-MysqL-8.24.0-12.el7.x86_64.rpm | 35 kB 00:00:00 Running transaction checkRunning transaction testTransaction test succeededRunning transaction Installing : rsyslog-MysqL-8.24.0-12.el7.x86_64 1/1 Verifying : rsyslog-MysqL-8.24.0-12.el7.x86_64 1/1 Installed: rsyslog-MysqL.x86_64 0:8.24.0-12.el7 Complete![root@test-centos7-node1 ~]# rpm -ql rsyslog-MysqL/usr/lib64/rsyslog/omMysqL.so/usr/share/doc/rsyslog-8.24.0/MysqL-createDB.sql[root@test-centos7-node1 ~]#
3）导入数据库和表，然后在其数据库里创建一个用于rsyslog连接数据库的专有账号
[root@test-centos7-node1 ~]# rpm -ql rsyslog-MysqL/usr/lib64/rsyslog/omMysqL.so/usr/share/doc/rsyslog-8.24.0/MysqL-createDB.sql[root@test-centos7-node1 ~]# MysqL < /usr/share/doc/rsyslog-8.24.0/MysqL-createDB.sql[root@test-centos7-node1 ~]# MysqLWelcome to the MariaDB monitor.

4）配置rsyslog加载omMysqL模块将local1、local2收集的日志存入数据库中
[root@test-centos7-node1 ~]# grep "omMysqL" /etc/rsyslog.conf$ModLoad omMysqLlocal1.* :omMysqL:192.168.0.10,Syslog,rsyslog,adminlocal2.* :omMysqL:192.168.0.10,admin[root@test-centos7-node1 ~]#
5）重启rsyslog和httpd后访问httpd服务，然后在其数据库里查看对应的表里是否存有日志
[root@test-centos7-node1 ~]# systemctl restart rsyslog httpd [root@test-centos7-node1 ~]# curl -I http://192.168.0.10/wordpresshttp/1.1 301 Moved PermanentlyDate: Mon,27 Jan 2020 17:08:30 GMTServer: Apache/2.4.6 (CentOS)Location: http://192.168.0.10/wordpress/Content-Type: text/HTML; charset=iso-8859-1[root@test-centos7-node1 ~]# MysqLWelcome to the MariaDB monitor.

提示：可以看到数据库里已经有我们刚才的访问日志了。到此收集日志记录到数据库的过程就实现了，接下来我们把前端展示工具搭建好就可以把数据库里的日志展示出来
6）上传loganalyzer到/var/ww/HTML/下，并解压（注意在httpd服务器上放一份的同时PHP-fpm服务器上也放一份）
[root@test-centos7-node1 HTML]# lswordpress[root@test-centos7-node1 HTML]# rzrz waiting to receive. zmodem trl+C ȡ 100% 1022 KB 1022 KB/s 00:00:01 0 Errorsgz...[root@test-centos7-node1 HTML]# tar xf loganalyzer-3.6.5.tar.gz [root@test-centos7-node1 HTML]# lsloganalyzer-3.6.5 loganalyzer-3.6.5.tar.gz wordpress[root@test-centos7-node1 HTML]# cd loganalyzer-3.6.5[root@test-centos7-node1 loganalyzer-3.6.5]# lsChangeLog contrib copYING doc INSTALL src[root@test-centos7-node1 loganalyzer-3.6.5]# cp -a src ../log[root@test-centos7-node1 loganalyzer-3.6.5]# cd ..[root@test-centos7-node1 HTML]# lslog loganalyzer-3.6.5 loganalyzer-3.6.5.tar.gz wordpress[root@test-centos7-node1 HTML]# scp -r log 192.168.0.30:/var/www/HTML/root@192.168.0.30's password: install.PHP 100% 41KB 1.0MB/s 00:00 export.PHP 100% 12KB 309.3KB/s 00:00 searchhelpers.Js 100% 6181 1.5MB/s 00:00 common.Js 100% 9434 2.0MB/s 00:00 reports.PHP 100% 4146 110.2KB/s 00:00 details.PHP 100% 16KB 2.6MB/s 00:00 defaults.CSS 100% 2039 521.7KB/s 00:00 highlight.CSS 100% 1032 314.3KB/s 00:00 menu.CSS 100% 1194 25.9KB/s 00:00 msgparser.class.PHP 100% 2425 73.3KB/s 00:00 logstreamconfigmongodb.class.PHP 100% 2573 420.8KB/s 00:00 logstreamconfig.class.PHP 100% 5439 904.0KB/s 00:00 msgparser.apache2common.class.PHP ……省略部分内容
7）用浏览器访问192.168.0.10/log安装loganalyzer
提示：上面安装界面提示我们没有config.PHP文件，需要我们新建一个这样的文件，并且权限得是666的权限
[root@test-centos7-node3 ~]# cd /var/www/HTML/[root@test-centos7-node3 HTML]# lslog wordpress[root@test-centos7-node3 HTML]# cd log/[root@test-centos7-node3 log]# lsadmin classes details.PHP images Js reports.PHP themesasktheoracle.PHP convert.PHP doc include lang search.PHP userchange.PHPBitstreamVeraFonts cron export.PHP index.PHP login.PHP statistics.PHPchartgenerator.PHP CSS favicon.ico install.PHP reportgenerator.PHP templates[root@test-centos7-node3 log]# touch config.PHP[root@test-centos7-node3 log]# chmod 666 config.PHP[root@test-centos7-node3 log]#
提示：把需要的文件创建好，授好权后，我们点击recheck
提示：安装完毕后，它提示我们错误500，我们知道错误500是服务器内部错误，我们需要在PHP-fpm上面找原因，我们先看看PHP-fpm的错误日志吧
[root@test-centos7-node3 log]# cd /var/log/PHP-fpm/[root@test-centos7-node3 PHP-fpm]# lserror.log www-error.log[root@test-centos7-node3 PHP-fpm]# tail www-error.log [14-Feb-2020 16:00:06 UTC] PHP Notice: Undefined index: VIEwStringCharacterlimit in /var/www/HTML/log/install.PHP on line 800[14-Feb-2020 16:00:06 UTC] PHP Notice: Undefined index: VIEwEntrIEsPerPage in /var/www/HTML/log/install.PHP on line 801[14-Feb-2020 16:00:06 UTC] PHP Notice: Undefined index: VIEwEnableDetailPopups in /var/www/HTML/log/install.PHP on line 802[14-Feb-2020 16:00:06 UTC] PHP Notice: Undefined index: EnableIPAddressResolve in /var/www/HTML/log/install.PHP on line 803[14-Feb-2020 16:00:06 UTC] PHP Notice: Undefined index: UserDBEnabled in /var/www/HTML/log/install.PHP on line 904[14-Feb-2020 16:00:06 UTC] PHP Warning: UnkNown: open(/var/lib/PHP/session/sess_b7f7ckbngimv44nhs20dpl7807,O_RDWR) Failed: No such file or directory (2) in UnkNown on line 0[14-Feb-2020 16:00:06 UTC] PHP Warning: UnkNown: Failed to write session data (files).

Please verify that the current setting of session.save_path is correct (/var/lib/PHP/session) in UnkNown on line 0[root@test-centos7-node3 PHP-fpm]#
说明：PHP-fpm错误日志提示我们说/var/www/HTML/log/config.PHP的第86行语法错误
提示：前三个值是我们设置安装loganalyzer的第三步，它这里没有写进来，我们需要手动填一下即可
@H_133_301@
提示：修改好后，我们在用浏览器访问下192.168.0.10/log看看问题解决没有
提示：还是告诉我们错误500，我们再来看看PHP-fpm的错误日志，看看它提示我们那里错了
提示：它又告诉我们99行有错误，我们去看看呢
提示：这个错误和上面一样，没有给值，我们可以从后面的解释看看，这个表示什么；它说如果启用，将自动解析IP地址内联消息，并将结果添加到IP后面的括号{}中；那说明这选项要么启动，要么关闭，那我们就填一个1启用嘛
提示：我们改完配置文件后，保存在用浏览器访问192.168.0.10/log看看现在是否可以访问了
提示：可以看到是可以访问了，我们看到我们访问httpd的日志都有记录，并显示在我们搭建的loganalyzer上面
我们点击statistics可能没有图标展示，这是因为我们的服务器上没有安装PHP-gd这个包，安装好了，重启PHP-fpm后，在刷新就有了
[root@test-centos7-node3 log]# yum install PHP-gd -y[root@test-centos7-node3 log]# systemctl restart PHP-fpm
提示：我们才搭建好数据量很少，所以看到画的图也不是很好。我们可以把其他主机的日志也接入到数据库中，当数据量比较大时，我们看统计图就可以看到那个主机的日志占比等等信息。如下
到此我们就把httpd的访问日志用rsyslog给收集到数据库中，然后通过loganalyzer 给图形化展示出来了。
