[root@host2 mysql]# /etc/init.d/mysqld stop Shutting down MySQL.. [ OK ] [root@host2 mysql]#
2、进入/usr/local更换软连接指定到mysql5.7
[root@host2 local]# ls bin games lib libexec mysql mysql-5.7.16-linux-glibc2.5-x86_64 mysql-utilities-1.6.5.tar.gz share etc include lib64 my.cnf mysql-5.6.34-linux-glibc2.5-x86_64 mysql-utilities-1.6.5 sbin src [root@host2 local]# unlink mysql
创建新的链接
[root@host2 local]# ln -s mysql-5.7.16-linux-glibc2.5-x86_64 mysql [root@host2 local]# ll total 712 drwxr-xr-x. 2 root root 4096 Jun 28 2011 bin drwxr-xr-x. 2 root root 4096 Jun 28 2011 etc drwxr-xr-x. 2 root root 4096 Jun 28 2011 games drwxr-xr-x. 2 root root 4096 Jun 28 2011 include drwxr-xr-x. 2 root root 4096 Jun 28 2011 lib drwxr-xr-x. 2 root root 4096 Jun 28 2011 lib64 drwxr-xr-x. 2 root root 4096 Jun 28 2011 libexec -rw-r--r--. 1 root root 2754 Nov 6 15:44 my.cnf lrwxrwxrwx. 1 root root 34 Mar 8 15:34 mysql -> mysql-5.7.16-linux-glibc2.5-x86_64 drwxr-xr-x. 12 mysql mysql 4096 Feb 27 18:33 mysql-5.6.34-linux-glibc2.5-x86_64 drwxr-xr-x. 11 root mysql 4096 Nov 19 00:01 mysql-5.7.16-linux-glibc2.5-x86_64 drwxr-xr-x. 7 7161 31415 4096 Feb 28 02:00 mysql-utilities-1.6.5 -rw-r--r--. 1 root root 668241 Feb 28 01:59 mysql-utilities-1.6.5.tar.gz drwxr-xr-x. 2 root root 4096 Jun 28 2011 sbin drwxr-xr-x. 5 root root 4096 Nov 6 22:15 share drwxr-xr-x. 2 root root 4096 Jun 28 2011 src
3、启动数据库并进入数据库
[root@host2 local]# /etc/init.d/mysqld start Starting MySQL.............................................[ OK ].............................. [root@host2 local]# mysql -u root -p Enter password: Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 2 Server version: 5.7.16-log MySQL Community Server (GPL)
(可以看到数据库已经到5.7版本了)

4、更新数据结构(生产环境使用mysql_upgrade更新的时候加-s参数 不重建表)
[root@host2 local]# mysql_upgrade -p123 -s mysql_upgrade: [Warning] Using a password on the command line interface can be insecure. The --upgrade-system-tables option was used, databases won't be touched. Checking if update is needed. Checking server version. Running queries to upgrade MySQL server. Upgrading the sys schema. Upgrade process completed successfully. Checking if update is needed.
至此升级成功
5、进入数据库查看
mysql> show databases; +--------------------+ | Database | +--------------------+ | information_schema | | mysql | | performance_schema | | sys | | test | +--------------------+ 可以看到sys库已经存在,但是直接安装的5.7的库是没有test库的,这里sys和test同时存在说明是从5.6升级到5.7
