CentOS6.5下RPM安装Mysql5.6

一、升级操作

1、卸载旧版本

  • 查看MySQL旧版本

  rpm -qa|grep mysql

  rpm -qa|grep mariadb

  • 卸载MySQL
  rpm -e --nodeps mysql-5.1.73-7.el6.x86_64  rpm -e --nodeps mysql-connector-odbc-5.1.5r1144-7.el6.x86_64  rpm -e --nodeps mysql-libs-5.1.73-7.el6.x86_64  rpm -qa|grep mysql
  • 删除数据目录
  ls  -l  /var/lib|grep mysql
  rm -rf /var/lib/mysql

数据目录可以备份移走。mysqld服务在初始化时会检查数据目录是否存在:如果数据目录不存在,mysqld则会创建它;如果数据目录存在,且不是空目录(即包含有文件或子目录),mysqld会显示一条错误信息并中止:
[ERROR] --initialize specified but the data directory exists. Aborting.

2、安装MySQL5.6

  • 准备好MySQL的安装包
  MySQL-client-5.6.30-1.el6.x86_64.rpm
  MySQL-devel-5.6.30-1.el6.x86_64.rpm
  MySQL-server-5.6.30-1.el6.x86_64.rpm
  • 安装MySQL包
  rpm -ivh MySQL-client-5.6.30-1.el6.x86_64.rpm
  rpm -ivh MySQL-devel-5.6.30-1.el6.x86_64.rpm  rpm -ivh MySQL-server-5.6.30-1.el6.x86_64.rpm
3、初始化数据库
  • 启动数据库
  [root@hbwb11 software]# /etc/init.d/mysql start
  Starting MySQL                                             [  OK  ]
  [root@hbwb11 software]#
  • 检查数据库运行状态
  [root@hbwb11 software]# /etc/init.d/mysql status
  MySQL running (5753)                                     [  OK  ]
  至此可以判断MySQL基本安装成功了!!!!
  • 找到临时密码
  [root@hbwb11 software]# more /root/.mysql_secret
  # The random password set for the root user at Wed Sep 28 15:55:25 2016 (local time): LSM8vTnqNGr9ArQs

  • 登陆修改密码
  mysql> SET PASSWORD=PASSWORD(‘Atae123$‘);
  Query OK, 0 rows affected (0.00 sec)
  mysql> exit
  Bye


4、设置root用户远程访问
  • 设置root远程访问
  use mysql;GRANT ALL PRIVILEGES ON *.* TO ‘root‘@‘%‘ IDENTIFIED BY ‘abc@123‘ WITH GRANT OPTION;  ‘%‘代表任意地址,也可以指定IP

  select host, user from user;
  FLUSH PRIVILEGES;
  • 设置防火墙

  在-A RH-Firewall-1-INPUT -j REJECT –reject-with icmp-host-prohibited之前,添加

 

  -A INPUT -m state --state NEW -m tcp -p tcp --dport 3306 -j ACCEPT
  • 重启防火墙

 

  service iptables restart
