前言：
之前的博文写过分布式安装LAMP搭建Discuz https://blog.csdn.net/weixin_43815140/article/details/105031305
和rpm搭建nginx，mysql，php于一身的lnmp‘
https://blog.csdn.net/weixin_43815140/article/details/105163108
今天搞个分开部署的lnmp
所需环境:
再做之前，先开放端口或者关闭防火墙和selinux，以免无法访问。
| 名称 | IP |
|---|---|
| nginx-1.16.1（centos7.2） | 192.168.10.2 |
| mysql-5.6（centos7.2） | 192.168.10.4 |
| php7.2(centos7.2) | 192.168.10.6 |
| 测试机 | 192.168.10.3 |
在192.168.10.2安装nginx
1>// 编辑官方yum源
[root@nginx~]# cat /etc/yum.repos.d/nginx.repo
[nginx-stable]
name=nginx stable repo
baseurl=http://nginx.org/packages/centos/7/$basearch/
gpgcheck=0
enabled=1
[root@nginx ~]#
2>//yum安装nginx
[root@nginx~]# yum -y install nginx
[root@nginx~]# systemctl start nginx
[root@nginx~]# systemctl enable nginx
3>//测试nginx是否可以访问
[root@localhost ~]# curl http://192.168.10.2
<!DOCTYPE html>

<p><em>Thank you for using nginx.</em></p>
</body>
</html>
ok，nginx已经安装好，现在安装mysql
在192.168.10.4安装mysql
1>//使用本地rpm包安装mysql，拷贝到/my目录
[root@mysql ~]# cd /my
[root@mysql my]# ls
mysql-community-client-5.6.47-2.el7.x86_64.rpm
mysql-community-common-5.6.47-2.el7.x86_64.rpm
mysql-community-libs-5.6.47-2.el7.x86_64.rpm
mysql-community-server-5.6.47-2.el7.x86_64.rpm
perl-Compress-Raw-Bzip2-2.061-3.el7.x86_64.rpm
perl-Compress-Raw-Zlib-2.061-4.el7.x86_64.rpm
perl-Data-Dumper-2.145-3.el7.x86_64.rpm
perl-DBI-1.627-4.el7.x86_64.rpm
perl-IO-Compress-2.061-2.el7.noarch.rpm
perl-Net-Daemon-0.48-5.el7.noarch.rpm
perl-PlRPC-0.2020-14.el7.noarch.rpm
[root@mysql my]#
2>//安装mysql
[root@mysql my]# yum -y localinstall /my/*
[root@mysql my]# systemcal start mysqld
3>//监听端口，确认是否开启
[root@lnmp ~]# netstat -anpt | grep 3306
tcp6 0 0 :::3306 :::* LISTEN 3634/mysqld
[root@localhost ~]#
4>//给MySQL设置密码
[root@lnmp ~]# mysql_secure_installation #根据提示修改密码为123.com
[root@lnmp ~]# mysql -uroot -p'123.com' #登录mysql
在192.168.10.6安装PHP
1>//准备第三方epel扩展源
[root@phpserver ~]# rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
[root@phpserver ~]# rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm
2>//安装PHP7.2
[root@lnmp ~]# yum -y install php72w php72w-cli php72w-common php72w-devel php72w-embedded php72w-gd php72w-mbstring php72w-pdo php72w-xml php72w-fpm php72w-mysqlnd php72w-opcache
3>//安装完成后，先不着急开启，修改/etc/php-fpm.d/www.conf文件
[root@phpserver ~]# cat /etc/php-fpm.d/www.conf | grep -v '^;' | grep -v '^$'
[www]
user = php
group = php
listen = 192.168.10.6:9000
listen.allowed_clients = 192.168.10.2
pm = dynamic
pm.max_children = 50
pm.start_servers = 5
pm.min_spare_servers = 5
pm.max_spare_servers = 35
slowlog = /var/log/php-fpm/www-slow.log
php_admin_value[error_log] = /var/log/php-fpm/www-error.log
php_admin_flag[log_errors] = on
php_value[session.save_handler] = files
php_value[session.save_path] = /var/lib/php/session
php_value[soap.wsdl_cache_dir] = /var/lib/php/wsdlcache
注意：listen = 192.168.10.6:9000 指向本机监听php-fpm；
listen.allowed_clients = 192.168.10.2 指向nginx主机
4>//开启php-fpm，监听端口
[root@phpserver ~]# systemctl start php-fpm
[root@phpserver ~]# netstat -anpt | grep php-fpm
tcp 0 0 192.168.10.6:9000 0.0.0.0:* LISTEN 38364/php-fpm: mast
配置nginx配置文件，使其能与php协同工作，nginx
处理一些静态页面请求，php处理动态请求
编辑nginx配置文件
修改/etc/nginx/conf.d/blog.conf虚拟主机文件（conf.d下存放的是虚拟主机文件，以这个为例。）
[root@nginx ~]# vim /etc/nginx/conf.d/blog.conf
server {
listen 80;
server_name blog.benet.com; #网站域名
root /www; #网站根目录
index index.php index.html; #索引页
location ~ \.php$ {
root /www;
fastcgi_pass 192.168.10.6:9000; #写php-fpm的地址，转发给它工作
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
}
~
注意：$document_root和root 属性一样，也可以用/wordpress代替。
客户端修改/etc/hosts文件，使其能域名解析到192.168.10.2
php创建info.php测试页,客户端访问测试
[root@phpserver ~]# cat /wordpress/info.php
<?php
phpinfo();
?>
[root@localhost ~]#
和之前一样，搭建个WordPress小博客网站，需要把源码包拷贝到nginx和php里，解压授权
创建数据库并给用户授权
mysql> create database blog;
Query OK, 1 row affected (0.00 sec)
mysql> grant all on blog.* to lisi@'192.168.10.%' identified by '123.com';
Query OK, 0 rows affected (0.00 sec)
mysql> exit
Bye
创建网站根目录/www,源码包解压后移动到这里(下面步骤nginx,php都要做),因为/www目录为网站根目录，不知道里面会有什么文件，静态就交给nginx处理，动态交给php。
mkdir /www
unzip wordpress-4.9.4-zh_CN.zip
mv /wordpress/* /www
chmod -R 777 /www
客户端测试，访问blog.benet.com
根据提示安装就好
