安装MySQL

1. 上传MySQL-server-5.5.48-1.linux2.6.x8664.rpm到Linux上

2. 解压ta包 得到一大堆rpm文件
   tar -xvf MySQL-5.6.25-1.el6.x86_64.rpm-bundle.tar

     MySQL-client-5.6.25-1.el6.x86_64.rpm
     MySQL-devel-5.6.25-1.el6.x86_64.rpm
     MySQL-embedded-5.6.25-1.el6.x86_64.rpm
     MySQL-server-5.6.25-1.el6.x86_64.rpm
     MySQL-shared-5.6.25-1.el6.x86_64.rpm
     MySQL-shared-compat-5.6.25-1.el6.x86_64.rpm
     MySQL-test-5.6.25-1.el6.x86_64.rpm

3. rpm安装mysql-server
   rpm -ivh MySQL-server-5.6.25-1.el6.x86_64.rpm

4. 出现错误
   file /usr/share/mysql/charsets/cp1256.xml from install of MySQL-server-5.6.25-1.el6.x86_64 conflicts with file from package mariadb-libs-1:5.5.56-2.el7.x86_64

5. 卸载 mariadb-libs-1:5.5.56-2.el7.x86_64 解决依赖
   rpm -e –nodeps mariadb-libs-1:5.5.56-2.el7.x86_64
6. 再次执行第三步 安装server
7. 安装客户端
   rpm -ivhMySQL-client-5.6.25-1.el6.x86_64.rpm
8. 启动mysql
   service mysql start
9. 初始化mysql
   /usr/bin/mysql_secure_installation
10. 测试mysql
    mysql -u root -p

注意事项

初始化mysql时可能出现问题

• 先关闭mysql
  service mysql stop
• 跳过检查
  service mysql start –skip-grant-tables

• 进入mysql 设置密码

  mysql> update mysql.user set password=PASSWORD('newpassword') where User='root'; 
  mysql> flush privileges; 
  mysql> quit 

• 重启mysql
  service mysql start
• 连接
  mysql -u root -p

备注

• 修改mysql密码
  set password for root@localhost = password('123');
