2.将mysql文件上传至虚拟机

3. 查看centos安装的mysql

[[email protected] local]# rpm -qa|grep mysql
mysql-libs-5.1.71-1.el6.x86_64

4.卸载mysql

[[email protected] local]# rpm -e --nodeps mysql-libs-5.1.71-1.el6.x86_64

5.解压mysql

[[email protected] mysql]# tar -xvf MySQL-5.6.39-1.el6.x86_64.rpm-bundle.tar
MySQL-embedded-5.6.39-1.el6.x86_64.rpm
MySQL-test-5.6.39-1.el6.x86_64.rpm
MySQL-shared-5.6.39-1.el6.x86_64.rpm
MySQL-server-5.6.39-1.el6.x86_64.rpm
MySQL-devel-5.6.39-1.el6.x86_64.rpm
MySQL-client-5.6.39-1.el6.x86_64.rpm
MySQL-shared-compat-5.6.39-1.el6.x86_64.rpm

6.通过rpm -ivh安装（按照顺序）

[[email protected] mysql]# rpm -ivh MySQL-client-5.6.39-1.el6.x86_64.rpm

[[email protected] mysql]# rpm -ivh MySQL-devel-5.6.39-1.el6.x86_64.rpm

[[email protected] mysql]# rpm -ivh MySQL-server-5.6.39-1.el6.x86_64.rpm

[[email protected] mysql]# rpm -ivh MySQL-shared-5.6.39-1.el6.x86_64.rpm

7. mysql5.6数据库会自动生成随机密码，通过安装的日志查询到密码在 /root/.mysql_secret 文件里

. centos6.5安装mysql5.6

8. 复制生成的随机密码

[[email protected] ~]# cat .mysql_secret
# The random password set for the root user at Sat Sep 15 11:25:09 2018 (local time): 0NHZ5NAnEpBNDBBT

9.启动mysql

[[email protected] ~]# service mysql start

10.第一次密码就使用刚拷贝.mysql_secret文件里的随机密码：0NHZ5NAnEpBNDBBT

[[email protected] ~]# mysql -u root -p
Enter password:

mysql> exit
Bye

11.设置密码

mysql> set password = password('123456')；

Query OK, 0 rows affected (0.01 sec)

mysql> exit
Bye

12.添加服务和开机自启

[[email protected] ~]# chkconfig --add mysql
[[email protected] ~]# chkconfig mysql on

13. 这时候通过navicat 链接数据库还是链接不了，进入mysql设置连接用户

mysql> grant all privileges on *.* to 'root' @'%' identified by '123456';
Query OK, 0 rows affected (0.01 sec)

mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)

mysql> exit
Bye

14.开放系统端口

[[email protected] ~]# /sbin/iptables -I INPUT -p tcp --dport 3306 -j ACCEPT
[[email protected] ~]# /etc/rc.d/init.d/iptables save
iptables: Saving firewall rules to /etc/sysconfig/iptables:[ OK ]

完成！
