linux免安装包快速安装mysql5.56

Posted 2021-01-09 460i

1. 第一步就是看linu是否安装了mysql，经过rpm -qa|grep mysql查看到centos下安装了mysql5.1，那就开始卸载咯

          

 

centos6.5下yum安装mysql5.6

 

　　2 接下来就是卸载mysql5.1了，命令：rpm -e mysql-libs --nodeps

       

 

　　3 yum中之后mysql5.1，安装还是5.1，现在就要去增加一个新的repo

        命令：rpm -Uvh http://mirror.steadfast.net/epel/6/i386/epel-release-6-8.noarch.rpm

       

 

 

　　4 一共需要增加两个repo，现在增加另一个

　　命令：rpm -Uvh http://rpms.famillecollet.com/enterprise/remi-release-6.rpm

        

 

　　5 现在查看一些是否增加成功了

　　命令：yum --enablerepo=remi,remi-test list mysql mysql-server

       

　　

　　6 接下来就是安装mysql5.56了

　　命令：yum --enablerepo=remi,remi-test install mysql mysql-server

        

 

　　7出现这个东西的时候一定要选择y。不然神都救不了你，就要重新安装了

       

 

 　　8：看到下面这个图片证明你的mysql安装成功了

        

 

　　

　　9 接下来需要启动一下mysql

　　命令：/etc/init.d/mysqld start

        

 

       10 下面这条命令设置开机自启动，省的我们每次开机就去启动一下mysql了

　　命令：chkconfig --levels 345 mysqld on

        

 

 

　　11 要启用MySQL 安全设置请输入以下命令

　　命令：/usr/bin/mysql_secure_installation

 

　　

 　　 一直选 y

 　　

 

　　12  到这里就要验证一下mysql是否安装成功了。如果输入看到以下界面的话，那么你就安装成功了。犒劳一下自己吧。

连接数据库命令：mysql  -u用户，-p密码

　　

mysql默认端口是3306，如果需要修改端口

如需要修改端口：

//登陆mysql

       [[email protected] ~]# mysql -uroot –p  

 

//查看端口

mysql> show global variables like ‘port‘;

 

+---------------+-------+

| Variable_name | Value |

+---------------+-------+

| port          | 3306  |

+---------------+-------+

//修改etc文件夹下的my.cnf

[[email protected] etc]# vi my.cnf

Lunix  允许开放端口：

 

命令：vi /etc/sysconfig/iptables

阿里云允许开放端口：

 可百度查询如何设置阿里云允许端口开放（因为我自己用的是阿里云服务器，其他服务器好像不用这样做）

 

Mysql允许远程连接

先登陆mysql mysql -u用户  -p密码

然后执行命令： grant all privileges on *.* to ‘root‘@‘%‘ identified by ‘root‘;

mysql> grant all privileges on *.* to ‘root‘@‘%‘ identified by ‘root‘;

Query OK, 0 rows affected (0.00 sec)

mysql> flush privileges;

Query OK, 0 rows affected (0.00 sec)

 

好了，可以用navicat连接了，（我用navicat，很方便），祝大家都能一次性安装成功
