本文主要介绍了如何使用云服务器的Linux系统手工搭建LNMP平台，并部署WordPress环境。WordPress简称WP，最初是一款博客系统，后逐步演化成一款免费的CMS（内容管理系统/建站系统）。该指导具体操作以CentOS 7.6 64位操作系统为例。

安装Nginx

# cd /usr/local/src

# wget http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm

# rpm -ivh nginx-release-centos-7-0.el7.ngx.noarch.rpm

# yum -y install nginx

执行以下命令，启动Nginx并设置开机启动。

# systemctl start nginx

# systemctl enable nginx

使用浏览器访问 “http://服务器IP地址”，显示如下页面，说明Nginx安装成功

安装MySQL

# rpm -Uvh http://dev.mysql.com/get/mysql57-community-release-el7-8.noarch.rpm

# yum -y install mysql-community-server

依次执行以下命令，启动MySQL服务并设置开机自启动。

# systemctl start mysqld

# systemctl enable mysqld

执行以下命令，获取安装MySQL时自动设置的root用户密码。

grep 'temporary password' /var/log/mysqld.log

回显如下类似信息。

执行以下命令，并按照回显提示信息进行操作，加固MySQL。

# mysql_secure_installation

Securing the MySQL server deployment.

Enter password for user root: #输入上一步骤中获取的安装MySQL时自动设置的root用户密码
The existing password for the user account root has expired. Please set a new password.

New password: #设置新的root用户密码

Re-enter new password: #再次输入密码
The 'validate_password' plugin is installed on the server.
The subsequent steps will run with the existing configuration of the plugin.
Using existing password for root.

Estimated strength of the password: 100
Change the password for root ? ((Press y|Y for Yes, any other key for No) : N #是否更改root用户密码，输入N

... skipping.
By default, a MySQL installation has an anonymous user,
allowing anyone to log into MySQL without having to have
a user account created for them. This is intended only for
testing, and to make the installation go a bit smoother.
You should remove them before moving into a production
environment.

Remove anonymous users? (Press y|Y for Yes, any other key for No) : Y #是否删除匿名用户，输入Y
Success.

Normally, root should only be allowed to connect from 'localhost'. This ensures that someone cannot guess at the root password from the network.

Disallow root login remotely? (Press y|Y for Yes, any other key for No) : Y #禁止root远程登录，输入Y
Success.

By default, MySQL comes with a database named 'test' that anyone can access. This is also intended only for testing, and should be removed before moving into a production environment.

Remove test database and access to it? (Press y|Y for Yes, any other key for No) : Y #是否删除test库和对它的访问权限，输入Y
- Dropping test database...
Success.

- Removing privileges on test database...
Success.

Reloading the privilege tables will ensure that all changes
made so far will take effect immediately.

Reload privilege tables now? (Press y|Y for Yes, any other key for No) : Y #是否重新加载授权表，输入Y
Success.

All done!

依次执行以下命令，安装PHP 7和一些所需的PHP扩展。

# rpm -Uvh https://mirror.webtatic.com/yum/el7/epel-release.rpm

# rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm

# yum -y install php70w-tidy php70w-common php70w-devel php70w-pdo php70w-mysql php70w-gd php70w-ldap php70w-mbstring php70w-mcrypt php70w-fpm

验证PHP的安装版本。

# php -v

执行以下命令，启动PHP服务并设置开机自启动。

# systemctl start php-fpm

# systemctl enable php-fpm

修改Nginx配置文件以支持PHP。

执行以下命令打开配置文件“default.conf”。

# vi /etc/nginx/conf.d/default.conf

按i键进入编辑模式。

修改打开的“default.conf”文件。

在所支持的主页面格式中添加php格式的主页，如下所示：

 location / {
        root   /usr/share/nginx/html;
        index index.php index.html index.htm;
    }

取消如下内容的注释，并设置字体加粗部分为Nginx的默认路径，如下图所示：

location ~ \.php$ {
        root           html;
        fastcgi_pass   127.0.0.1:9000;
        fastcgi_index  index.php;
        fastcgi_param  SCRIPT_FILENAME /usr/share/nginx/html$fastcgi_script_name;
        include        fastcgi_params;
    }
