Centos 7 安装Wordpress详细过程

Centos 7 安装Wordpress

安装Centos 7

1. 在VMWARE安装Centos 7(步骤略)

2. 备份原有的yum源文件，更新yum源为阿里云

[root@localhost yum.repos.d]# ls | xargs -t -i mv {} {}.bak
[root@localhost yum.repos.d]# ls -alh
total 48K
drwxr-xr-x.   2 root root  252 Apr  2 08:12 .
drwxr-xr-x. 139 root root 8.0K Apr  2 08:09 ..
-rw-r--r--.   1 root root 1.7K Apr  7  2020 CentOS-Base.repo.bak
-rw-r--r--.   1 root root 1.3K Apr  7  2020 CentOS-CR.repo.bak
-rw-r--r--.   1 root root  649 Apr  7  2020 CentOS-Debuginfo.repo.bak
-rw-r--r--.   1 root root  314 Apr  7  2020 CentOS-fasttrack.repo.bak
-rw-r--r--.   1 root root  630 Apr  7  2020 CentOS-Media.repo.bak
-rw-r--r--.   1 root root 1.3K Apr  7  2020 CentOS-Sources.repo.bak
-rw-r--r--.   1 root root 7.4K Apr  7  2020 CentOS-Vault.repo.bak
-rw-r--r--.   1 root root  616 Apr  7  2020 CentOS-x86_64-kernel.repo.bak

[root@localhost yum.repos.d]# curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo

[root@localhost yum.repos.d]# yum clean cache
[root@localhost yum.repos.d]# yum makecache

3. 更新一下系统,然后最好做一下快照

   [root@localhost yum.repos.d]# yum update
   

安装LNMP环境

1. 关闭防火墙

   a. 确认防火墙当前状态

   [root@localhost ~]# systemctl status firewalld.service
   ● firewalld.service - firewalld - dynamic firewall daemon
      Loaded: loaded (/usr/lib/systemd/system/firewalld.service; enabled; vendor preset: enabled)
      Active: active (running) since Sun 2023-04-02 08:22:54 EDT; 1min 43s ago
        Docs: man:firewalld(1)
    Main PID: 837 (firewalld)
       Tasks: 2
      CGroup: /system.slice/firewalld.service
              └─837 /usr/bin/python2 -Es /usr/sbin/firewalld --nofork --nopid
   
   Apr 02 08:22:53 localhost.localdomain systemd[1]: Starting firewalld - dynamic firewall daemon...
   Apr 02 08:22:54 localhost.localdomain systemd[1]: Started firewalld - dynamic firewall daemon.
   Apr 02 08:22:54 localhost.localdomain firewalld[837]: WARNING: AllowZoneDrifting is enabled. This is considered an insecure configuration option. It will be removed in a future release. Ple...bling it now.
   Hint: Some lines were ellipsized, use -l to show in full.
   

   b. 关闭防火墙

   [root@localhost ~]# systemctl stop firewalld.service
   [root@localhost ~]# systemctl disable firewalld.service
   Removed symlink /etc/systemd/system/multi-user.target.wants/firewalld.service.
   Removed symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.
   

2. 关闭Selinux,修改为SELINUX=disabled

   [root@localhost ~]# cat /etc/selinux/config
   
   # This file controls the state of SELinux on the system.
   # SELINUX= can take one of these three values:
   #     enforcing - SELinux security policy is enforced.
   #     permissive - SELinux prints warnings instead of enforcing.
   #     disabled - No SELinux policy is loaded.
   SELINUX=disabled
   # SELINUXTYPE= can take one of three values:
   #     targeted - Targeted processes are protected,
   #     minimum - Modification of targeted policy. Only selected processes are protected.
   #     mls - Multi Level Security protection.
   SELINUXTYPE=targeted
   

3. 安装nginx,由于nginx位于第三方的yum源里面，而不在centos官方yum源里面

[root@localhost ~]# wget https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm

[root@localhost opt]# rpm -ivh epel-release-latest-7.noarch.rpm
warning: epel-release-latest-7.noarch.rpm: Header V4 RSA/SHA256 Signature, key ID 352c64e5: NOKEY
Preparing...                          ################################# [100%]
Updating / installing...
   1:epel-release-7-14                ################################# [100%]

[root@localhost opt]# yum install -y nginx

验证一下nginx是否安装成功：

[root@localhost opt]# nginx -v
nginx version: nginx/1.20.1

说明安装成功！

4. 安装mysql

   [root@localhost opt]# sudo rpm -Uvh  http://dev.mysql.com/get/mysql57-community-release-el7-9.noarch.rpm
   

[root@localhost opt]# sudo yum -y install mysql-community-server --nogpgcheck

运行以下命令验证是否安装成功：

[root@localhost opt]# mysql -V
mysql  Ver 14.14 Distrib 5.7.41, for Linux (x86_64) using  EditLine wrapper

运行以下命令启动和开机启动Myssql:

[root@localhost opt]# systemctl start mysqld
[root@localhost opt]# systemctl enable mysqld

5. 安装PHP

   a. 更新yum源

   sudo yum install \
   https://repo.ius.io/ius-release-el7.rpm \
   https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
   

b. 运行以下命令添加Webtatic源

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

c. 安装PHP

sudo yum -y install php70w-devel php70w.x86_64 php70w-cli.x86_64 php70w-common.x86_64 php70w-gd.x86_64 php70w-ldap.x86_64 php70w-mbstring.x86_64 php70w-mcrypt.x86_64  php70w-pdo.x86_64   php70w-mysqlnd  php70w-fpm php70w-opcache php70w-pecl-redis php70w-pecl-mongodb

d.验证PHP是否安装成功

[root@localhost opt]# php -v
PHP 7.0.33 (cli) (built: Dec  6 2018 22:30:44) ( NTS )
Copyright (c) 1997-2017 The PHP Group
Zend Engine v3.0.0, Copyright (c) 1998-2017 Zend Technologies
    with Zend OPcache v7.0.33, Copyright (c) 1999-2017, by Zend Technologies

6. 配置NGINX

   • 添加或修改location /配置信息。

             location / {
                 index index.php index.html index.htm;
             }
     

   • 添加或修改location ~ .php$配置信息。

             #添加下列信息，配置Nginx通过fastcgi方式处理您的PHP请求。
             location ~ .php$ {
                 root /usr/share/nginx/html;    #将/usr/share/nginx/html替换为您的网站根目录，本文使用/usr/share/nginx/html作为网站根目录。
                 fastcgi_pass 127.0.0.1:9000;   #Nginx通过本机的9000端口将PHP请求转发给PHP-FPM进行处理。
                 fastcgi_index index.php;
                 fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
                 include fastcgi_params;   #Nginx调用fastcgi接口处理PHP请求。
             }
     

启动Nginx

[root@localhost ~]# systemctl start nginx
[root@localhost ~]# systemctl enable nginx
Created symlink from /etc/systemd/system/multi-user.target.wants/nginx.service to /usr/lib/systemd/system/nginx.service.

7. 配置mysql

   a. 运行以下命令，查看/var/log/mysqld.log文件，获取并记录root用户的初始密码。

   [root@localhost ~]# grep 'temporary password' /var/log/mysqld.log
   2023-04-02T12:43:47.099622Z 1 [Note] A temporary password is generated for root@localhost: ecz+LMihI1g=
   

[root@localhost ~]# mysql_secure_installation

8. 配置PHP

   在网站根目录创建phpinfo.php文件

   [root@localhost ~]# echo '<?php echo phpinfo(); ?>' > /usr/share/nginx/html/phpinfo.php
   

运行以下命令，启动PHP-FPM。

[root@localhost ~]# systemctl start php-fpm

设置开机启动php-fpm

[root@localhost ~]# systemctl enable php-fpm

访问phpinfo.php页面

至此已经成功的将php,mysql以及nginx安装配置完成。

安装Wordpress

1. 创建数据库huawen_db

mysql> create database huawen_db;
Query OK, 1 row affected (0.00 sec)

2. 创建数据库用户和密码

mysql> CREATE USER AAAAAAAAAAAAAA@localhost IDENTIFIED BY 'xxxxxxx';
Query OK, 0 rows affected (0.00 sec)

设置wordpressuser访问wordpress数据库权限

mysql> GRANT ALL PRIVILEGES ON huawen_db.* TO AAAAAAAAAAAAAr@localhost IDENTIFIED BY 'xxxxxxx';
Query OK, 0 rows affected, 1 warning (0.00 sec)

mysql> FLUSH PRIVILEGES;
Query OK, 0 rows affected (0.00 sec)

mysql> exit

3. 下载最新版本的wordpress包

[root@localhost opt]# wget http://wordpress.org/latest.tar.gz

[root@localhost opt]# tar -zxvf latest.tar.gz

并拷贝到nginxu网站根目录

[root@localhost opt]# rsync -avP ./wordpress/ /usr/share/nginx/html/

4. 编辑wp-config.php文件，配置数据库名、用户名和密码

5. 此时访问ip,即可完成wordpress的安装
