当前信息
mysql安装目录 /usr/local/mysql/
数据目录/usr/local/mysql/data
1. 下载新版本
下载5.7.2版本mysql并解压
[root@localhost ~]# wget
https://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-5.7.22-el7-x86_64.tar.gz
[root@localhost ~]#tar -zxvf mysql-5.7.22-el7-x86_64.tar.gz -C /usr/local/
[root@localhost ~]#cd /usr/local/
[root@localhost ~]#mv mysql-5.7.22-el7-x86_64/ mysql57
停止数据库
[root@localhost ~]# service mysql stop
Shutting down MySQL. SUCCESS!
将数据库和所有数据备份
安装目录备份
[root@localhost ~]# cp -rp /usr/local/mysql /usr/local/mysql56
数据备份
[root@localhost ~]# cd /
[root@localhost /]# cp -rp data data56
启动文件备份
[root@localhost /]# cd /etc/init.d/
[root@localhost init.d]# cp mysql mysql56
配置文件备份
[root@localhost init.d]# cp /etc/my.cnf /etc/my.cnf_56
2.数据库升级
①删除原basedir并替换
[root@localhost ~]# cd /usr/local/
[root@localhost local]# ls
bin games lib libexec mysql56 sbin
src
etc include lib64 mysql mysql57 share
[root@localhost local]# rm -rf mysql
[root@localhost local]# mv mysql57 mysql
记得修改新mysql权限
[root@localhost local]# chown -R mysql.mysql mysql
②替换新版mysql启动脚本
我这边默认所以不需要调整如果有变化还需要修改地址
[root@localhost local]# cp /usr/local/mysql/support-files/mysql.server
/etc/init.d/mysqlcp: overwrite ‘/etc/init.d/mysql’? y
[root@localhost local]# vim /etc/init.d/mysql
编写新启动脚本 将basedir和datadir填写进去
basedir=/usr/local/mysql
datadir=/data
③启动mysql
[root@localhost local]# service mysql start
Starting MySQL… SUCCESS!
查看进程和端口确认启动
④升级数据字典
[root@localhost local]# /usr/local/mysql/bin/mysql_upgrade -uroot -p
