MySQL init script and configuration

一个简单脚本init-mysql.sh，用于初始化刚安装MySQL, 更改数据库的存入目录至/adm/mysql, 包括创建必要的目录，删除不需要的目录，设置root初始密码，删除anonymous用户，删除无用的数据库test, 不允许root帐号远程连接数据库。如下:

 

init-mysql.sh

#!/bin/bash service mysql stop mkdir -pv /adm/mysql/{data,log,pid,tmp} chown -R mysql.mysql /adm/mysql chmod -R 0755 /adm/mysql mysql_install_db --user=mysql --ldata=/adm/mysql/data /bin/cp ./my.cnf /etc/ chmod 0600 /etc/my.cnf cd /var/lib/mysql/ /bin/ls | sed '/mysql.sock/d' | xargs rm -rf cd - service mysql start /usr/bin/mysql_secure_installation <<EOF y bbnd_adm bbnd_adm y y y y EOF service mysql restart

 

一个my.cnf文件，用于设定MySQL的配置, 如下：

my.cnf
