### 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][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][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。

### 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>
    <html>
    <head>
    <title>Welcome to nginx!</title>
    <style>
        body { 
            width: 35em;
            margin: 0 auto;
            font-family: Tahoma, Verdana, Arial, sans-serif;
        }
    </style>
    </head>
    <body>
    <h1>Welcome to nginx!</h1>
    <p>If you see this page, the nginx web server is successfully installed and
    working. Further configuration is required.</p>
    
    <p>For online documentation and support please refer to
    <a href="http://nginx.org/">nginx.org</a>.<br/>
    Commercial support is available at
    <a href="http://nginx.com/">nginx.com</a>.</p>
    
    <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 ~]#

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MzgxNTE0MA_size_16_color_FFFFFF_t_70]  
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
