按照以下方法安装会有个问题，那就是使用mysqldump等命令时，可能会提示socket文件找不到，需要添加参数--socket=/data/mysql/run/mysql.sock，或者把my.cnf里的socket对应目录路径改为/tmp/mysql.sock
以下内容为一键安装脚本。脚本仅适用于测试环境，生产环境请谨慎适用！
#!/bin/bash
#yum install openssl openssl-devel libaio* -y > /dev/null
rpm -qa |grep mysql

useradd -g mysql mysql

请在MySQL安装完成后，可根据自己的具体需求逐条在命令行中运行以下命令
mysql -e "DELETE FROM mysql.user WHERE User='';"
mysql -e "DELETE FROM mysql.user WHERE host='localhost';"
mysql -e "DELETE FROM mysql.user WHERE host='localhost.localdomain';"
mysql -e "DELETE FROM mysql.user WHERE host='::1';"
mysql -e "SELECT host, user, authentication_string FROM mysql.user WHERE user = 'root';"
mysql -e "GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '123456' WITH GRANT OPTION;"
mysql -e "GRANT ALL PRIVILEGES ON *.* TO 'root'@'127.0.0.1' IDENTIFIED BY '123456' WITH GRANT OPTION;"
mysql -e "FLUSH PRIVILEGES;"
PS：
如果安装失败，或者想卸载
只需要删除/data/mysql和/usr/local/mysql就可以卸载干净了
