bash-4.1# rpm -qa | grep mysql
rsyslog-mysql-4.6.2-2.el6.x86_64
php-mysql-5.3.2-6.el6.x86_64
mysql-server-5.1.47-4.el6.x86_64
mysql-connector-odbc-5.1.5r1144-7.el6.x86_64

bash-4.1# rpm -e mysql-devel-5.1.47-4.el6.x86_64 --nodeps
 

安装 mysql5.7 的相关包，注意安装顺序，因为包之间有依赖。

修改 mysql 的配置 my.cnf，关闭严格的密码设置，增加 validate_password=OFF 设置

bash-4.1# vi /etc/my.cnf
 
# For advice on how to change settings please see
# http://dev.mysql.com/doc/refman/5.7/en/server-configuration-defaults.html
 
[mysqld]
#
# Remove leading # and set to the amount of RAM for the most important data
# cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%.
# innodb_buffer_pool_size = 128M
#
# Remove leading # to turn on a very important data integrity option: logging
# changes to the binary log between backups.
# log_bin
#
# Remove leading # to set options mainly useful for reporting servers.
# The server defaults are faster for transactions and fast SELECTs.
# Adjust sizes as needed, experiment to find the optimal values.
# join_buffer_size = 128M
# sort_buffer_size = 2M
# read_rnd_buffer_size = 2M
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
validate_password=OFF
 
 
 

启动 mysql 服务

bash-4.1#
/etc/rc.d/init.d/mysqld start
Initializing MySQL database:                               [OK]
Installing validate password plugin:                       [OK]
Starting mysqld:                                           [OK]
 

有时 validate_password=OFF 会不生效，需要重启一下 mysql 服务

/etc/rc.d/init.d/mysqld restart

在 mysql 的安装目录下会产生相关文件

bash-4.1# ll /var/lib/mysql

进入 mysql 后，第一件事件就是要你改默认密码，由于已经关闭 v
alidate_password 功能，因此可以设置简单的密码

[root@c12 mysql57]# ./bin/mysql -u root -p
ERROR 1820 (HY000): You must reset your password using ALTER USER statement before executing this statement.
mysql> set password = password('zcxc1234')
