当许多人练习部署LNMP环境时,他们中的大多数都部署在同一个虚拟机上。但实际 *** 作中,我们一般是分开部署的。
今天,我将在LNMP环境中部署三台虚拟机。供参考!
网络拓扑图:
首先,准备3台虚拟机:
nginx:192
PHP192.168.1.202
mysql:192.168.1.217
首先,安装ngix(192.168.1.214):
#解决依赖 yum install -y gcc,openssl-devel,pcre-devel,zilb-devel pcre-devel #关闭防火墙和修改selinux service iptables stop chkconfig iptables off sed -i's#SELINUX=enforcing#SELINUX=disabled#g' /etc/selinux/config #添加一个nginx用户 [root@nginx ~]# groupadd -g 108 -r nginx [root@nginx ~]# useradd -u 108 -r -g 108 nginx [root@nginx ~]# tar zxvf nginx-1.6.0.tar.gz [root@nginx ~]# cd nginx-1.6.0 [root@nginx ~]# ./configure --prefix=/usr/local/ --sbin-path=/usr/sbin/nginx/ --conf-path=/etc/nginx/nginx.conf/ --error-log-path=/var/log/nginx/error.log/ --http-log-path=/var/log/nginx/access.log/ --pid-path=/var/run/nginx/nginx.pid/ --lock-path=/var/lock/nginx.lock/ --user=nginx/ --group=nginx/ --with-http_ssl_module/ --with-http_flv_module/ --with-http_stub_status_module/ --with-http_gzip_static_module/ --http-client-body-temp-path=/var/tmp/nginx/client/ --http-proxy-temp-path=/var/tmp/nginx/proxy/ --http-fastcgi-temp-path=/var/tmp/nginx/fcgi/ --http-uwsgi-temp-path=/var/tmp/nginx/uwsgi/ --http-scgi-temp-path=/var/tmp/nginx/scgi/ --with-pcre make && make installNginx启动脚本:

好了,LNMP的分离和部署完成了。如果部署中有任何问题,您可以将其发送到291406980@qq.com。
