首先centos7很坑爹。
其次，在centos7上安装mysql更坑爹。
特此记录一次坑爹历程后的唯一出路。
安装mysql
wget http://repo.mysql.com/mysql-community-release-el7-5.noarch.rpm sudo rpm -ivh mysql-community-release-el7-5.noarch.rpm sudo yum install mysql-server
配置
默认的/etc/my.cnf基本啥都没，参考版本：http://dev.mysql.com/doc/refman/5.6/en/server-configuration-defaults.html
最小版本：
# For advice on how to change settings please see # http://dev.mysql.com/doc/refman/5.6/en/server-configuration-defaults.html [mysqld] datadir=/var/lib/mysql socket=/var/lib/mysql/mysql.sock user=mysql # Disabling symbolic-links is recommended to prevent assorted security risks symbolic-links=0 # Recommended in standard MySQL setup sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES port=3306 collation-server = utf8_unicode_ci init-connect=‘SET NAMES utf8‘ character-set-server = utf8 default-storage-engine=InnoDB #default-table-type=InnoDB [mysqld_safe] log-error=/var/log/mysqld.log pid-file=/var/run/mysqld/mysqld.pid
创建mysql用户略
安装默认数据库！
mysql_install_db --datadir=/var/lib/mysql
启动服务
mysqld_safe
用service mysqld restart只会掉进很深很深的坑，此处省略一万字。
