准备环境
WordPress基于PHP开发的，本文采用Centos7.3、Nginx、MySQL5.7、PHP7.2部署。
设置阿里云镜像
- 备份原来的yum源
sudo cp /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup
- 设置阿里云的yum源
sudo wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
- 添加epel源
sudo wget -P /etc/yum.repos.d/ http://mirrors.aliyun.com/repo/epel-7.repo
- 清理缓存并生成新的缓存
sudo yum clean all
sudo yum makecache
安装Nginx
- 安装nginx源
执行以下命令，安装该rpm后，在/etc/yum.repos.d/目录中看到一个名为nginx.repo的文件
rpm -ivh http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm
- 安装nginx
yum install -y nginx
- nginx的默认目录
nginx配置路径：/etc/nginx/
pid目录：/var/run/nginx.pid
错误日志：/var/log/nginx/error
访问日志：/var/log/nginx/access.log
默认站点目录：/usr/share/nginx/html
只需知道nginx配置路径即可，一会儿仅需修改/etc/nginx/nginx.conf 以及/etc/nginx/conf.d/default.conf
- 修改配置文件
修改/etc/nginx/conf.d/default.conf中下面两段内容：
vi /etc/nginx/conf.d/default.conf
更改前：
location / {
root /usr/share/nginx/html;
index index.html index.htm;
}
更改后：
root /usr/share/nginx/html;
index index.html index.htm index.php;
location / {
try_files $uri $uri/ /index.php$is_args$args;
}
更改前：
#location ~ \.php$ {
# root html;
# fastcgi_pass 127.0.0.1:9000;
# fastcgi_index index.php;
# fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name;
# include fastcgi_params;
#}
更改后：
location ~ \.php$ {
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $request_filename;
include fastcgi_params;
}
修改 /etc/php-fpm.d/www.conf配置：
vi /etc/php-fpm.d/www.conf
将user = apache改为user = nginx，将group = apache改为group = nginx。
- nginx的常用命令
- 启动
/usr/sbin/nginx –s start
//或者
systemctl start nginx.service
- 重启
/usr/sbin/nginx –s reload
//或者
systemctl restart nginx.service
- 关闭
/usr/sbin/nginx –s stop
//或者
systemctl stop nginx.service
- 查看进程
ps -ef |grep nginx
安装MySQL
- 安装MySQL5.7
- 下载并安装MySQL官方的 Yum Repository
wget -i -c http://dev.mysql.com/get/mysql57-community-release-el7-10.noarch.rpm
- yum安装
yum -y install mysql57-community-release-el7-10.noarch.rpm
- 安装MySQL Sever
yum -y install mysql-community-server
- MySQL数据库设置
- 首先启动MySQL
systemctl start mysqld.service
- 查看MySQL运行状态
出现Active: active(runing)则表示启动成功
systemctl status mysqld.service
- 此时已运行成功并进入MySQL，执行以下命令找到密码
grep "password" /var/log/mysqld.log
- 进入数据库
mysql -uroot -p
- 在数据库中修改密码，下面的
new password填写新密码（密码设置格式为大小写、字符等）
ALTER USER 'root'@'localhost' IDENTIFIED BY 'new password';
- 由于安装了yum repository，以后每次yum操作都会自动更新，需要把这个卸载掉
yum -y remove mysql57-community-release-el7-10.noarch
安装PHP
- 如果之前已经安装先卸载之前的
yum -y remove php*
- 由于linux的yum源不存在php7.x，所以我们要更改yum源
rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm
- 安装php扩展，选择自己需要的
yum -y install php72w php72w-cli php72w-common php72w-devel php72w-embedded php72w-fpm php72w-gd php72w-mbstring php72w-mysqlnd php72w-opcache php72w-pdo php72w-xml
- 检验是否安装成功
php -V
- 开启服务
systemctl start nginx.service
systemctl start mysqlb.service
systemctl start php-fpm.service
安装WordPress
- 移除/usr/share/nginx/html内所有文件
cd /usr/share/nginx/html
rm 50x.html index.html
- 下载并解压wordpress安装包
wget https://cn.wordpress.org/wordpress-5.0.2-zh_CN.zip
tar -zxvf wordpress-5.0.2-zh_CN.zip
FAQ
- 远程连接MySQL出现1130错误，无法远程连接：error 1130: host '192.168.1.3' is not allowed to connect to this MySQL
mysql> use mysql
mysql> select host, user from user;
- 将相应用户数据表中的host字段改成'%';
update user set host='%' where user='root';
- 刷新保存，重新连接即可
flush privileges;
