centos 6.5下 mysql-community-server. 5.7.18-1.el6安装

使用下面的命令检查是否安装有MySQL Server

[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

[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：

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：

-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

mysql -uroot -p
