Centos 6.9 LAMP及WordPress教程

LAMP即Linux、Apache、MySQL、PHP的简称，目前仍有大量的企业以LAMP为架构的原型基础，搭建自己的服务应用。WordPress是成熟的博客平台产品，本文向广大用户和有兴趣的朋友介绍如何在滴滴云上搭建LAMP和WordPress。

其架构示意图如下：

购买了云主机相关产品（具体配置及数量请根据自身需求选定）以后，具体的LAMP及WordPress安装操作如下（不同的操作系统安装的命令略有不同，本文以centos 6.9为样例）：

一、Apache的安装

yum -y install httpd

安装完成后输入命令启动服务并且设置为开机启动

这里会出现一个提示：

Starting httpd: httpd: Could not reliably determine the server's fully qualified domain

可以事先避免，解决方法如下:

vi /etc/httpd/conf/httpd.conf

将下面一行注释掉

#ServerName www.example.com:80
service httpd start                                                   
chkconfig httpd on

#ServerName www.example.com:80

service httpd start

chkconfig httpd on

如果这一步安装正确，就可以直接在浏览器中输入公有IP地址，访问到Apache的测试页面。

二、Mysql安装

输入下面的命令安装Mysql服务，同时也设置为开机启动

[root@10-254-23-* dc2-user]# yum -y install mysql-server

[root@10-254-23-* dc2-user]# service mysqld start

[root@10-254-23-* dc2-user]# chkconfig mysqld on

如果这一步安装正确，可以输入下面的命令进入sql，默认的root用户没有设置密码，直接回车便可进入。

[root@10-254-23-8 dc2-user]# mysql -uroot -p

Enter password:

在sql终端中输入exit便可以退出
mysql> exit

Bye

[root@10-254-23-8 dc2-user]#
利用以下命令可以修改root用户的密码为 123456
[root@10-254-23-8 dc2-user]# mysqladmin -u root password 123456

三、PHP的安装

输入以下命令可以安装PHP及其组件

yum install php php-mysql –y

利用下面的命令安装常用的组件

yum -y install php-gd php-ldap php-odbc php-pear php-xml php-xmlrpc php-mbstring php-snmp php-soap curl curl-devel

安装完成后，可以编辑一个测试页面，测试php是否安装成功。

vi /var/www/html/info.php

输入以下内容

<?php
phpinfo();  
?>

<?php

phpinfo();

编辑完成后，重启httpd，在浏览器中输入http://x.x.x.x/info.php，查看版本信息。

四、WordPress的安装

安装wget，unzip命令

yum install -y wget
yum install -y unzip

yum install -y wget

yum install -y unzip

下载最新版本的WordPress并解压

wget http://wordpress.org/latest.zip
unzip latest.zip

wget http://wordpress.org/latest.zip

unzip latest.zip

编辑配置文件，修改数据库信息

cd wordpress/
cp wp-config-sample.php wp-config.php
vi wp-config.php

cd wordpress/

cp wp-config-sample.php wp-config.php

vi wp-config.php

修改数据库名称，用户名，密码。

// ** 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', 'abcD123456$');

// ** 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', 'abcD123456$');

配置完成后移动所有文件到/var/www/html目录下

cd ..
cp -rf wordpress/* /var/www/html/

cd ..

cp -rf wordpress/* /var/www/html/

WordPress安装完毕，之后对目录的权限进行编辑

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

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

建立数据库和用户，并设置密码

mysql -u root -p
mysql> CREATE DATABASE wordpressdb; 
Query OK, 1 row affected (0.00 sec)
mysql> CREATE USER wordpressuser@localhost IDENTIFIED BY '123456';
Query OK, 0 rows affected (0.00 sec)
mysql> GRANT ALL PRIVILEGES ON wordpressdb.* TO wordpressuser@localhost; 
Query OK, 0 rows affected (0.00 sec)
mysql> FLUSH PRIVILEGES;
Query OK, 0 rows affected (0.00 sec)
mysql> exit 
Bye

mysql -u root -p

mysql> CREATE DATABASE wordpressdb;

Query OK, 1 row affected (0.00 sec)

mysql> CREATE USER wordpressuser@localhost IDENTIFIED BY '123456';

Query OK, 0 rows affected (0.00 sec)

mysql> GRANT ALL PRIVILEGES ON wordpressdb.* TO wordpressuser@localhost;

Query OK, 0 rows affected (0.00 sec)

mysql> FLUSH PRIVILEGES;

Query OK, 0 rows affected (0.00 sec)

mysql> exit

Bye

重启服务

systemctl restart mysqld
systemctl restart httpd

systemctl restart mysqld

systemctl restart httpd

完成以上配置后，便可以登陆http://x.x.x.x/来访问你的博客了。
