刚开始编译安装MySQL的时候，都弄完了以后总是出错，很是郁闷，而且这个问题我在几个机器上都遇到过。今天查网络，终于弄明白是怎么回事了，原来是权限设置不对，虽然是所有者权限了，但是忘记设置所属组了。所以错在这里，望大家遇到童言的问题多检查检查，这么马虎，用了这么长时间才弄好，惭愧啊

以下是操作记录，从make install 完成以后开始记录，同时后边跟着一个网友的文章，，忘记出处了。先拿过来写了。

==================

[root@localhost mysql]# mysql

ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (111)

[root@localhost mysql]# service mysqld restart这里说明mysqld并没有启动，

MySQL manager or server PID file could not be found! [FAILED]

Starting MySQL/etc/init.d/mysqld: line 159: kill: (18977) - No such process

[FAILED]

[root@localhost mysql]# cd bin

[root@localhost bin]# ./mysql

ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (111) 这里就说了不能通过/tmp/mysql.sock连接数据库。

[root@localhost bin]# cd /tmp 进去检查，看到有这个文件，所以看别的原因。

[root@localhost tmp]# ls

gconfd-root mapping-root mysql.sock mysql-test-ports mysql-test-ports.sem scim-panel-socket:0-root VMwareDnD vmware-root vmware.txt

[root@localhost tmp]# cd /usr/local/mysql/

[root@localhost mysql]# pwd

/usr/local/mysql

[root@localhost mysql]# chown -R root:mysql . 忽然想起来了没有设置权限呢，开始设置权限

[root@localhost mysql]# ll

[root@localhost mysql]# mysqladmin -u root password 'uplooking'

mysqladmin: connect to server at 'localhost' failed

error: 'Can't connect to local MySQL server through socket '/tmp/mysql.sock' (111)'

Check that mysqld is running and that the socket: '/tmp/mysql.sock' exists! 又是上边一样的错误

[root@localhost mysql]# bin/mysql start

ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (111)
