mysql5.7.10安装

mkdir -p /opt/software/mysql && cd /opt/software/mysql

wget http://cdn.mysql.com//Downloads/MySQL-5.7/mysql-5.7.10-linux-glibc2.5-x86_64.tar.gz
tar -zxf mysql-5.7.10-linux-glibc2.5-x86_64.tar.gz

ln -s /opt/software/mysql/mysql-5.7.10-linux-glibc2.5-x86_64 /usr/local/m,ysql

groupadd mysql

useradd -r -g mysql mysql

mkdir -p /data/mysql/3306/{data,undo,etc}

chown -R mysql:mysql /data/mysql/3306/

配置文件可参考姜承尧老师的配置文件，实际上还是最小化为好，姜老师的是5.6和5.7通用，对于5.7来说，姜老师的配置文件里很多配的都是默认值，碰到这样的我在我自己的配置文件中就没写了：http://www.innomysql.net/article/21730.html

启动后可查看日志，日志里有临时密码，使用此密码登陆，重新生成密码

至此，mysql安装完成，正常启动，此时将skip_name_resolve=1打开，然后重启
