1、解压tar包
[root@hhu MySQL]# tar -xvf mysql-5.7.17-1.el6.x86_64.rpm-bundle.tar
mysql-community-test-5.7.17-1.el6.x86_64.rpm
mysql-community-embedded-5.7.17-1.el6.x86_64.rpm
mysql-community-embedded-devel-5.7.17-1.el6.x86_64.rpm
mysql-community-server-5.7.17-1.el6.x86_64.rpm
mysql-community-libs-compat-5.7.17-1.el6.x86_64.rpm
mysql-community-devel-5.7.17-1.el6.x86_64.rpm
mysql-community-client-5.7.17-1.el6.x86_64.rpm
mysql-community-libs-5.7.17-1.el6.x86_64.rpm
mysql-community-common-5.7.17-1.el6.x86_64.rpm
[root@hhu MySQL]# ls
mysql-5.7.17-1.el6.x86_64.rpm-bundle.tar mysql-community-embedded-devel-5.7.17-1.el6.x86_64.rpm
mysql-community-client-5.7.17-1.el6.x86_64.rpm mysql-community-libs-5.7.17-1.el6.x86_64.rpm
mysql-community-common-5.7.17-1.el6.x86_64.rpm mysql-community-libs-compat-5.7.17-1.el6.x86_64.rpm
mysql-community-devel-5.7.17-1.el6.x86_64.rpm mysql-community-server-5.7.17-1.el6.x86_64.rpm
mysql-community-embedded-5.7.17-1.el6.x86_64.rpm mysql-community-test-5.7.17-1.el6.x86_64.rpm
2、卸载已有老版本MySQL
[root@hhu MySQL]# rpm -qa|grep mysql
mysql-5.1.71-1.el6.x86_64
mysql-devel-5.1.71-1.el6.x86_64
mysql-libs-5.1.71-1.el6.x86_64
[root@hhu MySQL]# rpm -e mysql-5.1.71-1.el6.x86_64
error: Failed dependencies:
mysql = 5.1.71-1.el6 is needed by (installed) mysql-devel-5.1.71-1.el6.x86_64
[root@hhu MySQL]# rpm -e mysql-devel-5.1.71-
[root@hhu MySQL]# rpm -qa|grep mysql
mysql-5.1.71-1.el6.x86_64
mysql-libs-5.1.71-1.el6.x86_64
[root@hhu MySQL]# rpm -e mysql-5.1.71-1.el6.x86_64
[root@hhu MySQL]# rpm -e mysql-libs-5.1.71-1.el6.x86_64
error: Failed dependencies:
libmysqlclient.so.16()(64bit) is needed by (installed) postfix-2:2.6.6-2.2.el6_1.x86_64
libmysqlclient.so.16(libmysqlclient_16)(64bit) is needed by (installed) postfix-2:2.6.6-2.2.el6_1.x86_64
mysql-libs is needed by (installed) postfix-2:2.6.6-2.2.el6_1.x86_64
[root@hhu MySQL]# rpm -e mysql-libs-5.1.71-1.el6.x86_64 –nodeps 强制卸载
[root@hhu MySQL]# rpm -qa|grep mysql
[root@hhu MySQL]#
3、安装MySQL包，一共5个，会有依赖关系，安装顺序如下：
rpm -Uvh mysql-community-common-5.7.17-1.el6.x86_64.rpm
rpm -Uvh mysql-community-libs-5.7.17-1.el6.x86_64.rpm
rpm -Uvh mysql-community-libs-compat-5.7.17-1.el6.x86_64.rpm
rpm -Uvh mysql-community-client-5.7.17-1.el6.x86_64.rpm
rpm -Uvh mysql-community-server-5.7.17-1.el6.x86_64.rpm
[root@hhu MySQL]# ls
mysql-5.7.17-1.el6.x86_64.rpm-bundle.tar mysql-community-embedded-devel-5.7.17-1.el6.x86_64.rpm

4、获取超级数据库用户临时密码，登录，修改密码
[root@hhu MySQL]# grep ‘temporary password’ /var/log/mysqld.log
