1、获取安装文件mysql-5.7.16-1.el7.x86_64.rpm-bundle.tar
2、创建目录并解压
3、安装的rpm包如下
4、rpm -ivh mysql-community-common-5.7.16-1.el7.x86_64.rpm 就报错了。因为centos系统自带了mariadb
5、需要先卸载掉mariadb
6、依次安装如下rpm包rpm -ivh mysql-commu艘绒庳焰nity-common-5.7.16-1.el7.x86_64.rpmrpm -ivh mysql-community-libs-5.7.16-1.el7.x86_64.rpmrpm -ivh mysql-community-client-5.7.16-1.el7.x86_64.rpmrpm -ivh mysql-community-server-5.7.16-1.el7.x86_64.rpm
7、有很多应用还需要安装这个包rpm -ivh mysql-community-libs-compat-5.7.16-1.el7.x86_64.rpm
8、安装完成后初始化mysqld --initialize --user=mysql
9、会在/var/log/mysqld.log文件生成一个初始密码启动mysql，重置密码就能使用链路
