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 mail.cx.com 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!

配置postfix支持虚拟域与虚拟用户
说明： 1、启用虚拟域以后，需要取消中心域，即注释掉myhostname, mydestination, mydomain, myorigin几个指令；当然，你也可以把mydestionation的值改为你自己需要的。 2、对于MySQL-5.1以后版本，其中的服务脚本extmail.sql执行会有语法错误；可先使用如下命令修改extmail.sql配置文件，而后再执行。修改方法如下： # sed -i 's@TYPE=MyISAM@ENGINE=InnoDB@g' extmail.sql

##
## Mailbox locations and namespaces
##
# Location for users' mailboxes. The default is empty, which means that Dovecot
# tries to find the mailboxes automatically. This won't work if the user
# doesn't yet have any mail, so you should explicitly tell Dovecot the full
# location.
#
# If you're using mbox, giving a path to the INBOX file (eg. /var/mail/%u)
# isn't enough. You'll also need to tell Dovecot where the other mailboxes are
# kept. This is called the "root mail directory", and it must be the first
# path given in the mail_location setting.
#
# There are a few special variables you can use, eg.:
#
# %u - username
# %n - user part in user@domain, same as %u if there's no domain
# %d - domain part in user@domain, empty if there's no domain
# %h - home directory
#
# See doc/wiki/Variables.txt for full list. Some examples:
#
# mail_location = maildir:~/Maildir
# mail_location = mbox:~/mail:INBOX=/var/mail/%u
# mail_location = mbox:/var/mail/%d/%1n/%n:INDEX=/var/indexes/%d/%1n/%n

说明：如果mysql服务器是本地主机，即host=localhost时，如果mysql.sock文件不是默认的/var/lib/mysql/mysql.sock，可以使用host=“sock文件的路径”来指定新位置；例如，使用通用二进制格式安装的MySQL，其soc文件位置为/tmp/mysql.sock，相应地，connect应按如下方式定义。
connect = host=/tmp/mysql.sock dbname=extmail user=extmail password=extmail
