  • 启用CentOS6.5 64位安装时自带的MySQL数据库服务器

    本人在虚拟机上又安装了一台linux机器,作为MySQL数据库服务器用,在安装时选择了系统自带的MySQL服务器端,以下是启用步骤。

    首先开启mysqld服务

    #service mysqld start

    进入/usr/bin目录
    #cd /usr/bin

    设定mysql数据库root用户的密码
    #mysqladmin -u root password '123456'

    进入mysql数据库管理控制台
    #./mysql -u root -p
    Enter password:
    Welcome to the MySQL monitor.  Commands end with ; or g.
    Your MySQL connection id is 4
    Server version: 5.0.67 Source distribution

    Type 'help;' or 'h' for help. Type 'c' to clear the buffer.

    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)

    mysql> grant select,update,insert,delete on *.* to root@192.168.0.100 identified by "root";
    Query OK, 0 rows affected (0.00 sec)

    mysql> flush privileges;
    Query OK, 0 rows affected (0.00 sec)

    mysql> quit
    Bye

    上面的步骤是进行授权

    然后重启mysqld服务
    # service mysqld restart
    Stopping MySQL:                                            [  OK  ]
    Starting MySQL:                                            [  OK  ]

    再次进入mysql管理控制台
    # mysql -u root -p
    Enter password:
    Welcome to the MySQL monitor.  Commands end with ; or g.
    Your MySQL connection id is 2
    Server version: 5.0.67 Source distribution

    Type 'help;' or 'h' for help. Type 'c' to clear the buffer.

    mysql> use mysql
    Reading table information for completion of table and column names
    You can turn off this feature to get a quicker startup with -A

    Database changed
    mysql> update user set password=password('12345678') where user='root';
    Query OK, 5 rows affected (0.00 sec)
    Rows matched: 5  Changed: 5  Warnings: 0

    mysql> flush privileges;
    Query OK, 0 rows affected (0.00 sec)

    mysql> quit
    Bye

    以上步骤是修改root用户的密码

    之后开启防火墙的3306端口
    # vi /etc/sysconfig/iptables

    以下是/etc/sysconfig/iptables的内容,其中蓝色一行是新加的。这一行可以由上一行复制得到,方法是在22哪行按下yy,然后按p,然后点insert键进入编辑模式,修改22为3306,然后点esc,输入wq保存退出。
    # Firewall configuration written by system-config-firewall
    # Manual customization of this file is not recommended.
    *filter
    :INPUT ACCEPT [0:0]
    :FORWARD ACCEPT [0:0]
    :OUTPUT ACCEPT [0:0]
    -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT
    -A INPUT -p icmp -j ACCEPT
    -A INPUT -i lo -j ACCEPT
    -A INPUT -m state --state NEW -m tcp -p tcp --dport 22 -j ACCEPT
    -A INPUT -m state --state NEW -m tcp -p tcp --dport 3306 -j ACCEPT
    -A INPUT -j REJECT --reject-with icmp-host-prohibited
    -A FORWARD -j REJECT --reject-with icmp-host-prohibited
    COMMIT

    防火墙重启
    # service iptables restart
    iptables: Flushing firewall rules:                         [  OK  ]
    iptables: Setting chains to policy ACCEPT: filter          [  OK  ]
    iptables: Unloading modules:                               [  OK  ]
    iptables: Applying firewall rules:                         [  OK  ]

    之后就可以在192.168.0.100上用mysqlfront连接数据库了。
