当前版本:5.7.18
升级后版本:5.7.19
1.拷贝新版本文件到指定目录
[root@izwz9gxsbwybwg9n5xdi47z soft]# cp mysql-5.7.19-linux-glibc2.12-x86_64.tar.gz /opt/
2.解压缩
[root@izwz9gxsbwybwg9n5xdi47z opt]# tar -zxvf mysql-5.7.19-linux-glibc2.12-x86_64.tar.gz
[root@izwz9gxsbwybwg9n5xdi47z opt]# mv mysql-5.7.19-linux-glibc2.12-x86_64 mysql5719
3.创建相应的目录(根据自己数据库的配置文件创建)
mkdir -p /opt/mysql5719/db1/conf
mkdir -p /opt/mysql5719/db1/redolog
mkdir -p /opt/mysql5719/db1/mysqllog/binlog
mkdir -p /opt/mysql5719/db1/mysqllog/logfile
mkdir -p /opt/mysql5719/db1/mysqllog/relaylog
4.拷贝原来的配置文件到新的目录
[root@izwz9gxsbwybwg9n5xdi47z conf]# cp my.cnf /opt/mysql5719/db1/conf/
5.修改配置文件

6.赋予权限
[root@izwz9gxsbwybwg9n5xdi47z opt]# chown -R mysql:mysql ./mysql5719
7.启动
./mysqld_safe --defaults-file=/opt/mysql5719/db1/conf/my.cnf --user=mysql
8.运行mysql_upgrade升级数据字典
./mysql_upgrade -h localhost -uroot -pmysql -P3306
[root@izwz9gxsbwybwg9n5xdi47z bin]# ./mysql_upgrade -h localhost -uroot -pmysql -P3306
