RPM安装步骤
a. 检查是否已安装,grep的-i选项表示匹配时忽略大小写
[root@localhost JavaEE]#rpm -qa|grep -i mysql
mysql-libs-5.1.61-4.el6.x86_64
可见已经安装了库文件,应该先卸载,不然会出现覆盖错误。注意卸载时使用了--nodeps选项,忽略了依赖关系:
[root@localhost JavaEE]#rpm -e mysql-libs-5.1.61-4.el6.x86_64 --nodeps
2. 安装MySQL的服务器端软件,注意切换到root用户:
[root@localhost JavaEE]#rpm -ivh MySQL-server-5.5.29-2.el6.x86_64.rpm
安装完成后,安装进程会在Linux中添加一个mysql组,以及属于mysql组的用户mysql。可通过id命令查看:
[root@localhost JavaEE]#id mysql
uid=496(mysql)gid=493(mysql) groups=493(mysql)
MySQL服务器安装之后虽然配置了相关文件,但并没有自动启动mysqld服务,需自行启动:
[root@localhost JavaEE]#service mysql start
Starting MySQL.. SUCCESS!
可通过检查端口是否开启来查看MySQL是否正常启动:
[root@localhost JavaEE]#netstat -anp|grep 3306
tcp 0 0 0.0.0.0:3306 0.0.0.0:* LISTEN 34693/mysqld
c. 安装MySQL的客户端软件:
[root@localhost JavaEE]#rpm -ivh MySQL-client-5.5.29-2.el6.x86_64.rpm
如果安装成功应该可以运行mysql命令,注意必须是mysqld服务以及开启:
[root@localhost JavaEE]#mysql

Navicat windowns下远程连接linux端的mysql
我们需要建立到Linux上MySQL服务器的链接,创建一个链接,命名链接名称,填写服务器IP,登录用户和密码,然后进行链接~有可能链接时会出错,说是没有授权,类似于Host '192.168.1.3' is not allowed to connect to this MySQL server的错误~
这个错误原因是没有开放远程链接功能,可以在mysql命名行的客户端中对用户进行授权,例如使用命令GRANT ALL PRIVILEGES ON *.* TO 'root'@'%'IDENTIFIED BY ’password’ WITH GRANT OPTION;对root用户进行授权,然后就可以链接成功~
