卸载系统mysql:
rpm -qa|grep -i mysql
rpm -e --nodeps xxx

# linux
groupadd mysql
useradd -r -g mysql mysql
cd /usr/local
ln -s mysql-5.6.27-linux-glibc2.5-x86_64 mysql
cd mysql

# 将mysql/bin加入环境变量，也就是/etc/profile文件中

# 加入默认配置文件
bin/my_print_defaults --defaults-file=/usr/local/mysql/my.cnf

# 初始化数据文件
scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/mysql3306

scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/mysql3307

# 然后出来一大段英文大概教你怎么做

# 启动后先改密码

# 否则执行时指定配置文件

mysqld_multi --defaults-extra-file=/usr/local/mysql/my.cnf report
# or
mysqld_multi --defaults-file=/usr/local/mysql/my.cnf report
# or
mysqld_multi report

# 查看
mysqld_multi report

# 启动
mysqld_multi start 3306

# 停止
mysqld_multi stop 3306 --password=root
#or 最好用这个
mysqladmin -S /tmp/mysql_3306.sock -uroot -p shutdown

# 改密码

mysqladmin -S /tmp/mysql_3307.sock -u root password 'root'

# 创建授权新用户，开始使用
