Summary     : The MySQL server and related files
Description :
MySQL is a multi-user, multi-threaded SQL database server. MySQL is a
client/server implementation consisting of a server daemon (mysqld)
and many different client programs and libraries. This package contains
the MySQL server and some accompanying files and directories.
[root@localhost ~]# service mysqld start               #启动mysql服务
初始化 MySQL 数据库： Installing MySQL system tables...
OK
Filling help tables...
OK

To start mysqld at boot time you have to copy
support-files/mysql.server to the right place for your system

PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands:

/usr/bin/mysqladmin -u root password 'new-password'
/usr/bin/mysqladmin -u root -h localhost.localdomain password 'new-password'

Alternatively you can run:
/usr/bin/mysql_secure_installation

which will also give you the option of removing the test
databases and anonymous user created by default.  This is
strongly recommended for production servers.

See the manual for more instructions.

You can start the MySQL daemon with:
cd /usr ; /usr/bin/mysqld_safe &

You can test the MySQL daemon with mysql-test-run.pl
cd /usr/mysql-test ; perl mysql-test-run.pl

Please report any problems with the /usr/bin/mysqlbug script!

附：使用navicat软件进行连接mysql时需要进行的配置

1.在CentOS系统中防火墙默认是阻止3306端口的，我们要是想访问mysql数据库，我们需要这个端口，命令如下：

 /sbin/iptables -I INPUT -p tcp --dport 3306 -j ACCEPT

我们需要保存我们的操作，命令如下：

  /etc/rc.d/init.d/iptables save

此时我们可以查看端口的状态，命令如下：

 /etc/init.d/iptables status

当然如果你打开其他端口也一样，只需要把这个端口号换乘你需要的端口号即可。

 

 

2.修改远程连接的权限出现错误的解决方法：

 

GRANT ALL PRIVILEGES ON *.* TO 'YourUserName'@'%' IDENTIFIED BY "YourPassword";
