  • centos 安装mysql

    yum install mysql 装好了,

    运行mysql
    ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)。有文章说是权限问题,后来把权限搞成777也不行。说是没启动MYSQL。那就启动吧

    [root@localhost mysql]# service mysql start
    mysql: unrecognized service
    不行。。。网上也找不到个所以然来。说是用RC.D启动

    /etc/rc.d/init.d/mysqld start
    -bash: /etc/rc.d/init.d/mysqld: No such file or directory
    依然不行。

    后来找文章,有人是装的mysql-server.就把前面装的删了。删除用yum remove mysql  。YUM还是很方便的,呵呵。

    再yum install mysql-server

    装好了。启动

     [root@localhost mysql]# service mysql start
    mysql: unrecognized service

    再试

     [root@localhost mysql]# service mysqld start

    居然成功了!!!(红色是本人自己的试法)

    如果依旧。。。。。。。。继续下面的操作

    然后 /etc/rc.d/init.d/mysql 启动

    /etc/init.d/mysqld start
    Initializing MySQL database:  Installing MySQL system tables...
    110112 15:24:06 [Warning] option 'max_join_size': unsigned value 18446744073709551615 adjusted to 4294967295
    110112 15:24:06 [Warning] option 'max_join_size': unsigned value 18446744073709551615 adjusted to 4294967295

    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 mysql-test ; perl mysql-test-run.pl

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

    The latest information about MySQL is available on the web at
    http://www.mysql.com
    Support MySQL by buying support/licenses at http://shop.mysql.com
                                                               [  OK  ]
    Starting MySQL:                                            [  OK  ]

    好了。。竟然。。。呵呵

    加到自启动了吧。省的麻烦

    chkconfig mysqld on

    注意一下,这里是mysqld 不是mysql

    运行一下mysql

    [root@localhost /]# mysql
    Welcome to the MySQL monitor.  Commands end with ; or \g.
    Your MySQL connection id is 2
    Server version: 5.0.77 Source distribution

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

    呵呵,好了!问题解决了!

    再试试 [root@localhost mysql]# service mysqld restart
    Stopping MySQL:                                            [  OK  ]
    Starting MySQL:                                            [  OK  ]

    都OK了!
