centos6.6 安装 MYSQL 5.7.26

1.mkdir mysqlinstall #新建mysql的文件夹

2.tar -xvf mysql-5.7.26-1.el6.x86_64.rpm-bundle #解压mysql的安装包得到以下的安装文件

3.rpm -qa|grep postfix #卸载冲突的组件

4.yum install libaio #安装需要安装对应的组件

5.以此安装以下四个包：

• mysql-community-common-5.7.26-1.el6.x86_64.rpm
• mysql-community-libs-5.7.26-1.el6.x86_64.rpm
• mysql-community-client-5.7.26-1.el6.x86_64.rpm
• mysql-community-server-5.7.26-1.el6.x86_64.rpm

解决方法：可执行rpm -e --nodeps mysql-community-libs-5.1.13-1.el6.x86_64

• 安装 rpm -ivh mysql-community-server-5.7.26-1.el6.x86_64.rpm等包名;

6.service mysqld restart #重启mysql

7.grep password /var/log/mysqld.log #查看临时密码

8.mysql -u root -p #登录用户

9.set password = password('Mysql_1234'); #重置登录密码

10.service mysqld restart;#重启mysql
