[PHP知识库]Centos7部署LAMP搭建wordpress

1.介绍

LAMP环境就是Linux+Apache+Mysql+PHP。

2. 安装Apache Web服务器

Apache服务器Web服务器。运行以下命令安装：

yum install httpd

安装完成之后我们就可以运行以下命令启动Apache服务器了：

systemctl start httpd.service

之后我们就可以在浏览器中打开http://your_server_IP_address/?我们新安装的网站，检查一下Apache是否安装成功，正常运行。

?

以后重启服务器之后自动启动Apache服务器，可以运行以下命令：

systemctl enable httpd.service

?Apache服务器的网站文件默认在/var/www目录。

3. 安装Mysql(MariaDB)数据库

执行以下命令安装MariaDB数据库：

yum install mariadb-server mariadb

完成之后启动数据库：

systemctl start mariad

然后安装一个数据库安全脚本，去掉一些危险的默认设置：

mysql_secure_installation

然后会提示你输入数据库的root账号密码，如果是新安装的则输入空格，如下所示：

In order to log into MariaDB to secure it, we'll need the current
password for the root user.  If you've just installed MariaDB, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here.
Enter current password for root (enter for none):

然后我们输入空格，继续设置root密码：

Setting the root password ensures that nobody can log into the MariaDB
root user without the proper authorisation.
Set root password? [Y/n] Y
New password:
Re-enter new password:
Password updated successfully!
Reloading privilege tables..
 ... Success!
By default, a MariaDB installation has an anonymous user, allowing anyone
to log into MariaDB 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? [Y/n]
 ... 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? [Y/n]
 ... Success!
By default, MariaDB 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? [Y/n]
 - 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? [Y/n]
 ... Success!
Cleaning up...
All done!  If you've completed all of the above steps, your MariaDB
installation should now be secure.
Thanks for using MariaDB!

同样的，设置开机自动启动MariaDB数据库：

systemctl enable mariadb.service

在这里我提供数据库另外一种方法，与前面数据库是一样的两者是重复的

yum install -y mariadb-server            #yum安装mariadb
systemctl start mariadb          #启动mariadb
systemctl enable mariadb      #开机启动mariadb


进入mariadb进行设置
    在命令行输入以下命令进入mariadb
    mysql -uroot -p
    注:密码不用输入直接回车就行
    输入以下命令修改登录密码
    SET password for 'root'@'localhost'=password('password'); #修改数据库密码
    create database wordpress character set utf8 collate utf8_bin; #创建wordpress数据库实例
    grant all privileges on wordpress.* to 'user'@'localhost' identified by '123456';  #创建并授权user账户并授权使用123456访问localhost主机上wordpress数据库下的所有表

4. 安装PHP

运行以下命令安装PHP：

yum install php php-mysql

安装完成，重启一下Apache服务器：

systemctl restart httpd.service

PHP安全完成之后，我们可以在网站目录下面建立一个info.php的文件来查看php的安装情况我们在/var/www/html目录创建一个info.php的文件：

vi /var/www/html/info.php

其info.php内容如下：

<?php phpinfo(); ?>

我们我们安装PHP成功，浏览器打开http://your_server_IP_address/info.php?将会看到以下内容：

?

?5. 安装phpMyAdmin

phpMyAdmin是个管理MariaDB数据库的Web界面程序，可以装一个。

我们首先安装EPEL库，这个库提供很多额外的软件包：

yum install epel-release

完成之后直接安装phpMyAdmin：

yum install phpmyadmin

完成之后，我们设置phpMyAdmin的httpd设置：

vi /etc/httpd/conf.d/phpMyAdmin.conf

Alias /phpMyAdmin /usr/share/phpMyAdmin
Alias /phpmyadmin /usr/share/phpMyAdmin
<Directory /usr/share/phpMyAdmin/>
   AddDefaultCharset UTF-8
   <IfModule mod_authz_core.c>
     # Apache 2.4
     <RequireAny>
       Require ip 127.0.0.1
       Require ip ::1
     </RequireAny>
   </IfModule>
   <IfModule !mod_authz_core.c>
     # Apache 2.2
     Order Deny,Allow
     Deny from All
     Allow from 127.0.0.1
     Allow from ::1
   </IfModule>
</Directory>

从配置中可以看出，可以用http://192.168.232.131/phpmyadmin?去访问phpMyAdmin。实际上我们在浏览里打开这个地址是403 Forbidden，这是因为还有权限控制,我们更改一下权限：

<Directory /usr/share/phpMyAdmin/>
   AddDefaultCharset UTF-8
   <IfModule mod_authz_core.c>
     # Apache 2.4
     <RequireAny>
       #Require ip 127.0.0.1
       #Require ip ::1
        Require all granted
     </RequireAny>
   </IfModule>
   <IfModule !mod_authz_core.c>
     # Apache 2.2
     Order Deny,Allow
    # Deny from All
    # Allow from 127.0.0.1
    # Allow from ::1
      Allow from All
   </IfModule>
</Directory>

然后再重启以下Apache服务器：

systemctl restart httpd.service

在浏览器输入http://server_domain_or_IP/phpMyAdmin?，可以看到：

?

然后可以使用数据的root密码登录了。

6. 安装Wordpress?

6.1 创建数据库

我们先要创建Wordpress的数据库：

#登录数据库
mysql -u root -p
#创建数据库
CREATE DATABASE wordpress;
#创建数据库用户和密码
CREATE USER wordpressuser@localhost IDENTIFIED BY 'wordress_password';
#设置wordpressuser访问wordpress数据库权限
GRANT ALL PRIVILEGES ON wordpress.* TO wordpressuser@localhost IDENTIFIED BY 'wordress_password';
#刷新数据库设置
FLUSH PRIVILEGES;
#退出数据库
exit

6.2 安装Wordpress

我们先下载wordpress安装包：

wget http://wordpress.org/wordpress-5.0.4.tar.gz

然后解压出来，拷贝到/var/www/html/wordpress目录：

# 解压wordpress
tar xzvf wordpress-5.0.4.tar.gz
# 拷贝到/var/www/html/wordpress目录
rsync -avP ~/wordpress/ /var/www/html/wordpress/

然后编辑wp-config.php文件：

# 切换到wordpress目录
cd /var/www/html/wordpress
# 复制wp-config.php文件
cp wp-config-sample.php wp-config.php
# 编辑wp-config.php文件
vim wp-config.php

然后在配置文件里设置正确的值：

// ** MySQL settings - You can get this info from your web host ** //
/** The name of the database for WordPress */
define('DB_NAME', 'database_name_here');
/** MySQL database username */
define('DB_USER', 'username_here');
/** MySQL database password */
define('DB_PASSWORD', 'password_here');
/** MySQL hostname */
define('DB_HOST', 'localhost');

按照提示创建好博客，显示如下：
