腾讯云安装wordpress环境

准备 LNMP 环境或者Apache

LNMP

LNMP是 Linux、nginx、mysql 和 php 的缩写，是 WordPress 博客系统依赖的基础运行环境。我们先来准备 LNMP 环境

安装 Nginx
使用 yum 安装 Nginx：

yum install nginx -y

修改完成后，启动 Nginx：

nginx

将 Nginx 设置为开机自动启动：

chkconfig nginx on

Apache

查看httpd包是否可用：

# yum list | grep httpd

安装Apache

# yum install httpd -y

配置ServerName

# vi /etc/httpd/conf/httpd.conf
如果没有域名，则：ServerName localhost:80

启动httpd并且设置为开机启动

systemctl start httpd.service
systemctl enable httpd.service
chkconfig httpd on

如果启动失败,可能端口被占用,下边是查看端口被占用和kill进程的命令:

[root@VM_112_104_centos html]# lsof -i :80
COMMAND   PID  USER   FD   TYPE DEVICE SIZE/OFF NODE NAME
nginx   23604  root    6u  IPv4  54105      0t0  TCP *:http (LISTEN)
nginx   23604  root    7u  IPv6  54106      0t0  TCP *:http (LISTEN)
nginx   31869 nginx    6u  IPv4  54105      0t0  TCP *:http (LISTEN)
nginx   31869 nginx    7u  IPv6  54106      0t0  TCP *:http (LISTEN)
[root@VM_112_104_centos html]# kill -QUIT 23604
[root@VM_112_104_centos html]# kill -QUIT 31869
-bash: kill: (31869) - No such process
[root@VM_112_104_centos html]# lsof -i :80

安装目录介绍
Apache默认将网站的根目录指向/var/www/html 目录
默认的主配置文件是/etc/httpd/conf/httpd.conf
配置存储在的/etc/httpd/conf.d/目录

安装 MySQL

CentOS 7.0中，已经使用MariaDB替代了MySQL数据库.

[root@VM_112_104_centos ~]# yum -y install mariadb mariadb-server
[root@VM_112_104_centos ~]# systemctl start mariadb.service    #启动MariaDB
[root@VM_112_104_centos ~]# systemctl stop mariadb.service    #停止MariaDB
[root@VM_112_104_centos ~]# systemctl restart mariadb.service    #重启MariaDB
[root@VM_112_104_centos ~]# systemctl enable mariadb.service    #设置开机启动
[root@VM_112_104_centos ~]# cp /usr/share/mysql/my-huge.cnf /etc/my.cnf    #拷贝配置文件（注意：如果/etc目录下面默认有一个my.cnf，直接覆盖即可）
[root@VM_112_104_centos ~]# mysql_secure_installation    #给root设置密码
回车，根据提示输入Y
输入2次密码，回车
根据提示一路输入Y
最后出现：Thanks for using MySQL!
MariaDB密码设置完成，重新启动 MariaDB
[root@VM_112_104_centos ~]# systemctl restart mariadb.service

允许mysql远程访问

mysql默认是不允许远程访问的.

[root@VM_112_104_centos bak]# mysql -uroot -p
Enter password: 
Welcome to the MariaDB monitor.  Commands end with ; or \g.

MariaDB [scholar]> flush privileges;

MariaDB [scholar]>

如果有防火墙,需要做如下配置(此配置来自腾讯云文档):

#开放3306
firewall-cmd --permanent --add-port=3306/tcp 

systemctl restart firewalld.service

#查看端口是否开放
firewall-cmd --query-port=3306/tcp

#list
firewall-cmd --list-all

安装PHP

yum install php-fpm php-mysql -y

安装之后，启动 PHP-FPM 进程：

service php-fpm start

启动之后，可以使用下面的命令查看 PHP-FPM 进程监听哪个端口

[root@VM_112_104_centos ~]# netstat -nlpt | grep php-fpm
tcp        0      0 127.0.0.1:9000          0.0.0.0:*               LISTEN      27679/php-fpm: mast

把 PHP-FPM 也设置成开机自动启动：

[root@VM_112_104_centos ~]# chkconfig php-fpm on
Note: Forwarding request to 'systemctl enable php-fpm.service'.
Created symlink from /etc/systemd/system/multi-user.target.wants/php-fpm.service to /usr/lib/systemd/system/php-fpm.service.

安装并配置 WordPress

yum install wordpress -y

Copy WordPress文件到/var/www/html,修改文件夹权限:

chown -R apache:apache /var/www/html/
chmod -R 755 /var/www/html/
mkdir -p /var/www/html/wp-content/uploads
chown -R :apache /var/www/html/wp-content/uploads

修改配置文件:

cd /var/www/html
cp wp-config-sample.php wp-config.php 
vi wp-config.php

// * MySQL settings - You can get this info from your web host * // 
/* The name of the database for WordPress / 
define(‘DB_NAME’, ‘wordpressdb’);

/* mysql database username / 
define(‘DB_USER’, ‘wordpressuser’);

/* MySQL database password / 
define(‘DB_PASSWORD’, ‘123456’);

重启相关服务(以apache为例):

systemctl restart httpd.service
systemctl restart  mariadb.service

还有一种安装wordpress的方法:

# wget https://cn.wordpress.org/wordpress-4.5.2-zh_CN.tar.gz
# tar zxvf wordpress-4.5.2-zh_CN.tar.gz
# mv /srv/www/qcloud.zning.net/html/wordpress/* /srv/www/qcloud.zning.net/html

然后访问:

http://IP

就可以安装完毕!
