使用下面的命令检查是否安装有MySQL Server
1
|
[root@localhost etc]# rpm -qa | grep mysql // 这个命令就会查看该操作系统上是否已经安装了mysql数据库 |
有的话,我们就通过 rpm -e
命令 或者 rpm -e --nodeps
命令来卸载掉
1
2
|
[root@localhost ~]# rpm -e mysql // 普通删除模式 [root@localhost ~]# rpm -e --nodeps mysql // 强力删除模式,如果使用上面命令删除时,提示有依赖的其它文件,则用该命令可以对其进行强力删除 |
在删除完以后我们可以通过 rpm -qa | grep mysql
命令来查看mysql是否已经卸载成功!!

mysql -h主机地址 -u用户名 -p用户密码
1、例1:连接到本机上的MYSQL
找到mysql的安装目录,一般可以直接键入命令mysql -uroot -p,回车后提示你输密码,如果刚安装好MYSQL,超级用户root是没有密码的,故直接回车即可进入到MYSQL中
了,MYSQL的提示符是:mysql>
2、连接到远程主机上的MYSQL
假设远程主机的IP为:10.0.0.1,用户名为root,密码为123。则键入以下命令:
1
|
mysql -h10.0.0.1 -uroot -p123 |
(注:u与root可以不用加空格,其它也一样)
配置防火墙
防火墙的3306端口默认没有开启,若要远程访问,需要开启这个端口
打开/etc/sysconfig/iptables
在“-A INPUT –m state --state NEW –m tcp –p tcp –dport 22 –j ACCEPT”,下添加:
1
|
-A INPUT -m state --state NEW -m tcp -p tcp --dport 3306 -j ACCEPT |
然后保存,并关闭该文件,在终端内运行下面的命令,刷新防火墙配置:
service iptables restart OK,一切配置完毕,你可以访问你的MySQL了~
注意:增加的开放3306端口的语句一定要在icmp-host-prohibited之前
