1.查看linux版本、内核、cpu、内存
[root@localhost ~]# cat /etc/redhat-release CentOS Linux release 7.8.2003 (Core) [root@localhost ~]# [root@localhost ~]# uname -a Linux localhost.localdomain 3.10.0-1127.el7.x86_64 #1 SMP Tue Mar 31 23:36:51 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux [root@localhost ~]# [root@localhost ~]# [root@localhost ~]# cat /proc/version Linux version 3.10.0-1127.el7.x86_64 ([email protected]) (gcc version 4.8.5 20150623 (Red Hat 4.8.5-39) (GCC) ) #1 SMP Tue Mar 31 23:36:51 UTC 2020 [root@localhost ~]# nproc 8 [root@localhost ~]# free -g total used free shared buff/cache available Mem: 15 0 14 0 0 14 Swap: 7 0 7 [root@localhost ~]# echo $LANG en_US.UTF-8
2、创建互信，主机免密
SSH认证密钥对
ssh-keygen -t rsa -P '' -f ~/.ssh/id_rsa
到其他主机创建互信：
ssh-copy-id root@{target_host}
3、改主机名
vi /etc/hostname
4、主机映射hosts–域名解析
vi /etc/hosts
改完之后，同步到其他节点
-------正反向域名解析
5、关闭防火墙
进行安装任务，集群所有主机都必须关闭防火墙:
systemctl disable firewalld
systemctl stop firewalld
—查看状态：
systemctl status firewalld
6、禁用透明大页(THP)
首先检查THP的启用状态：
[root@localhost ~]#（cat /sys/kernel/mm/transparent_hugepage/defrag）
[always] madvise never
[root@localhost ~]# （cat /sys/kernel/mm/transparent_hugepage/enabled）
[always] madvise never
这个状态就说明都是启用的。我们这个时候当然可以逐个修改上述两文件，来禁用THP，但要想一劳永逸的令其永久生效，还是参考下列的步骤。
编辑rc.local文件：
vi /etc/rc.d/rc.local
增加下列内容：
if test -f /sys/kernel/mm/transparent_hugepage/enabled; then echo never > /sys/kernel/mm/transparent_hugepage/enabled fi if test -f /sys/kernel/mm/transparent_hugepage/defrag; then echo never > /sys/kernel/mm/transparent_hugepage/defrag fi
保存退出，然后赋予rc.local文件执行权限：
(chmod +x /etc/rc.d/rc.local )
最后重启系统，以后再检查THP应该就是被禁用了
[root@localhost ~]# (cat /sys/kernel/mm/transparent_hugepage/enabled) always madvise [never] [root@localhost ~]# (cat /sys/kernel/mm/transparent_hugepage/defrag) always madvise [never]
7、禁用交换分区
集群内所有主机禁用交换分区。
sysctl vm.swappiness=0
echo vm.swappiness=0 >> /etc/sysctl.conf
8、关闭SELinux和配置limits参数
1、更改SELinux为宽容模式。
setenforce 0
2、查看/etc/selinux/config文件，永久禁止SELinux自动启动。
查看：
cat /etc/selinux/config|grep SELINUX=
3、设置 SELINUX=disabled
sed -i "s/SELINUX=enforcing/SELINUX=disabled/g" /etc/selinux/config
4、集群所有主机设置umask，设置用户创建目录默认权限（用了root,没做这步）
umask 0022
echo umask 0022 >> /etc/profile
5、编辑/etc/security/limits.conf文件
追加以下内容：
- soft nofile 65535
- hard nofile 65535
- soft nproc 65535
- hard nproc 65535f
9、添加ambari和hdp的yum源
在另一篇博文
—>添加ambari-2.7.5的yum源
10、安装jdk
如果本地有rpm包：
yum -y localinstall /root/tmp/jdk-8u291-linux-x64.rpm
查看结果：
[root@bdtest-main02 tmp]# which java /usr/bin/java [root@bdtest-main02 tmp]# whereis java java: /usr/bin/java /usr/share/man/man1/java.1
11、时钟同步–chrony
–查看yum：
yum list|grep chrony
–安装：
yum install -y chrony
–编辑配置文件：
[root@bdtest-main01 ~]# vim /etc/chrony.conf # 使用 aliyun.com 项目中的公共服务器。以server开，理论上想添加多少时间服务器都可以 server ntp.aliyun.com iburst # 指定 NTP 客户端地址，以允许或拒绝连接到扮演时钟服务器的机器 allow 10.106.213.0/24 # 根据实际时间计算出服务器增减时间的比率，然后记录到一个文件中，在系统重启后为系统做出最佳时间补偿调整 driftfile /var/lib/chrony/drift # 如果系统时钟的偏移量大于1秒，则允许系统时钟在前三次更新中步进 makestep 1.0 3 # 启用实时时钟（RTC）的内核同步 rtcsync # 指定日志文件的目录 logdir /var/log/chrony
systemctl enable chronyd
systemctl start chronyd
–查看时间同步状态
timedatectl status
https://www.cnblogs.com/jhxxb/p/11526098.html
12、安装mysql
解压mysql压缩包
tar -zxvf mysql-5.7.34-linux-glibc2.12-x86_64.tar.gz -C /usr/local/ mv /usr/local/mysql-5.7.34-linux-glibc2.12-x86_64 /usr/local/mysql
vi /etc/my.cnf
—新建一个msyql组及用户
—新建msyql用户禁止登录shell
groupadd mysql useradd -r -s /sbin/nologin -g mysql mysql -d /usr/local/mysql---新建msyql用户禁止登录shell
mysql进行初始化 *** 作：
cd /usr/local/mysql
bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/data/mysql-work/mysql-data/
–可以cd /data/mysql-work/mysql-data/ 查看生成的内容
Mysql启用命令：
/usr/local/mysql/bin/mysqld_safe --user=mysql &
登录：
mysql -uroot -p
如果提示密码过期或错误，可重置密码
1.vim /etc/my.cnf
skip-grant-tables ##跳过权限认证
2.重启mysql
3.登录mysql，
[root@localhost ~]# mysql -uroot -p
Enter password:
MySQL [(none)]> use mysql;
MySQL [mysql]> UPDATe user SET `password_expired`='N' where user='root'; ##将密码过期修改为 密码不过期；
Query OK, 1 row affected (0.00 sec)
Rows matched: 1 Changed: 1 Warnings: 0
----select User,password_expired,authentication_string from user;
MySQL [mysql]> select * from mysql.user where user='root' G; #查看数据
MySQL [mysql]> UPDATe user SET `authentication_string` = PASSWORd('root') where User='root'; ##修改密码；
Query OK, 3 rows affected, 1 warning (0.00 sec)
Rows matched: 3 Changed: 3 Warnings: 1
MySQL [mysql]> flush privileges;
Query OK, 0 rows affected (0.00 sec)
MySQL [mysql]> exit;
添加mysql到系统服务：
cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld
重启主机，服务
查看：systemctl status mysql
设置mysql可以远程登录
MySQL [(none)]> GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' identified by 'root' WITH GRANT OPTION;
Query OK, 0 rows affected, 1 warning (0.01 sec)
MySQL [(none)]> flush privileges
-> ;
Query OK, 0 rows affected (0.01 sec)
MySQL [(none)]> exit
Bye
验证：
mysql -h{host.ip} -uroot -proot
13、mysql主备配置
创建mysql的主从同步账号，只能在从节点访问
MySQL [mysql]> CREATE USER 'dumper'@'10.106.213.75' IDENTIFIED BY 'dumper@#123'; Query OK, 0 rows affected (0.01 sec) MySQL [mysql]> grant replication slave on *.* to 'dumper'@'10.106.213.75' identified by 'dumper@#123'; Query OK, 0 rows affected, 1 warning (0.01 sec) MySQL [mysql]> flush privileges; Query OK, 0 rows affected (0.01 sec)
查看主节点的master信息
MySQL [(none)]> show master status; +-------------------------+----------+--------------+------------------+-------------------+ | File | Position | Binlog_Do_DB | Binlog_Ignore_DB | Executed_Gtid_Set | +-------------------------+----------+--------------+------------------+-------------------+ | mysql-master-bin.000006 | 3327 | | | | +-------------------------+----------+--------------+------------------+-------------------+ 1 row in set (0.00 sec)
在从节点执行：
MySQL [(none)]> CHANGE MASTER TO MASTER_HOST='10.106.213.71',MASTER_USER='dumper',MASTER_PASSWORD='dumper@#123',MASTER_LOG_FILE='mysql-master-bin.000006',MASTER_LOG_POS=3327;
MySQL [(none)]> start slave; -----启动slave
Query OK, 0 rows affected (0.00 sec)
MySQL [(none)]> show slave status G ---查看状态
*************************** 1. row ***************************
Slave_IO_State: Waiting for master to send event
Master_Host: 10.106.213.71
Master_User: dumper
Master_Port: 3306
Connect_Retry: 60
Master_Log_File: mysql-master-bin.000006
Read_Master_Log_Pos: 3327
Relay_Log_File: relay-log.000002
Relay_Log_Pos: 327
Relay_Master_Log_File: mysql-master-bin.000006
Slave_IO_Running: Yes
Slave_SQL_Running: Yes
Replicate_Do_DB:
14、创建mysql相关用户：ambari、hive
MySQL [(none)]> create database ambari; Query OK, 1 row affected (0.00 sec) MySQL [(none)]> CREATE USER 'ambari'@'%' IDENTIFIED BY 'ambari@#qa'; Query OK, 0 rows affected (0.00 sec) -----给用户授权数据库 MySQL [(none)]> GRANT ALL PRIVILEGES ON `ambari`.* TO 'ambari'@'%' WITH GRANT OPTION; Query OK, 0 rows affected (0.00 sec) MySQL [(none)]> flush privileges; Query OK, 0 rows affected (0.00 sec) MySQL [(none)]> show grants for ambari; +----------------------------------------------------------------------+ | Grants for ambari@% | +----------------------------------------------------------------------+ | GRANT USAGE ON *.* TO 'ambari'@'%' | | GRANT ALL PRIVILEGES ON `ambari`.* TO 'ambari'@'%' WITH GRANT OPTION | +----------------------------------------------------------------------+ 2 rows in set (0.00 sec)
15、安装ambari-server
yum install ambari-server
如果下载报错：
wget http://10.218.137.11/ambari/ambari/centos7/ambari/ambari-server-2.5.0.3-7.x86_64.rpm
本地安装：
yum localinstall ambari-server-2.5.0.3-7.x86_64.rpm
yum只下载不安装：
yum reinstall --downloadonly --downloaddir=/var/cache/yum/x86_64/7Server krb5-workstation.x86_64
初始化Ambari数据库连接配置:
ambari-server setup --jdbc-db=mysql --jdbc-driver=/usr/share/java/mysql-connector-java.jar
安装Ambari
ambari-server setup
Customize user account for ambari-server daemon [y/n] (n)? n(如果用普通用户安装Ambari-server,则选择Y) Enter user account for ambari-server daemon (root):hmaster(输入建立的普通用户) Path to JAVA_HOME: /usr/java/jdk1.8.0_291-amd64
进入mysql库的ambari库
source /var/lib/ambari-server/resources/Ambari-DDL-MySQL-CREATE.sql
启动ambari-server：
systemctl status ambari-server
systemctl restart ambari-server
日志：
tail -50f /var/log/ambari-server/ambari-server.log
16、ambari配置
打开ambari页面，默认密码admin/admin
给集群起名字
在redhat里面填写repo文件里面的路径
hive@#qa
ambari-server日志信息
