配置PHP-FPM

修改PHP-FPM配置文件

# 进入PHP-FPM配置文件目录 cd /etc/php-fpm.d # 备份原始配置文件 cp www.conf www.conf.bak # 修改配置文件 vi www.conf

添加以下内容到配置文件：

[www] user = nginx group = nginx listen = /var/run/php-fpm.sock listen.owner = nginx listen.group = nginx pm = dynamic pm.max_children = 50 pm.start_servers = 10 pm.min_spare_servers = 5 pm.max_spare_servers = 35

重启PHP-FPM服务

systemctl restart php-fpm

配置MySQL

初始化MySQL

# 初始化MySQL mysqld --initialize

修改MySQL密码

# 进入MySQL安全模式 mysql_secure_installation # 输入root用户密码，回车 # 设置root密码 # 移除匿名用户 # 禁用root用户远程登录 # 删除test数据库 # 退出安全模式

创建数据库和用户

# 登录MySQL mysql -u root -p # 创建数据库 CREATE DATABASE myweb; # 创建用户 CREATE USER 'myuser'@'localhost' IDENTIFIED BY 'mypassword'; # 授权用户 GRANT ALL PRIVILEGES ON myweb.* TO 'myuser'@'localhost'; # 刷新权限 FLUSH PRIVILEGES; # 退出MySQL EXIT
