安装extmail
安装extmail和extman
下载extmail和extman
https://zh.osdn.net/projects/sfnet_ds5752/downloads/yu/extmail-1.2.tar.gz/
https://zh.osdn.net/projects/sfnet_ds5752/downloads/yu/extman-1.1.tar.gz/
创建站点目录并解压、重命名extmail包
[root@CentOS7 src]# mkdir -p /var/www/extsuite
[root@CentOS7 src]# tar -zxvf extmail-1.2.tar.gz -C /var/www/extsuite/
[root@CentOS7 src]# mv /var/www/extsuite/extmail-1.2/ /var/www/extsuite/extmail
建立临时文件目录与session目录，并更改权限
[root@CentOS7 extmail]# mkdir -p /tmp/extmail/upload
[root@CentOS7 extmail]# chown -R postfix.postfix /tmp/extmail/
回到extman的下载目录下，解压extman包
cd /usr/local/src/
tar -zxvf extman-1.1.tar.gz -C /var/www/extsuite/
cd /var/www/extsuite/
mv extman-1.1/ extman
拷贝extman的配置文件
[root@CentOS7 extsuite]# cd extman/
[root@CentOS7 extman]# cp webman.cf.default webman.cf
更改cgi目录的属主属组
[root@CentOS7 extman]# chown -R postfix.postfix /var/www/extsuite/extman/cgi/
[root@CentOS7 extman]# chown -R postfix.postfix /var/www/extsuite/extmail/cgi/
配置数据库
导入数据库
[root@CentOS7 extman]# vim docs/extmail.sql
:%s/TYPE/ENGINE/
[root@CentOS7 extman]# mysql -uroot < docs/extmail.sql
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)
[root@CentOS7 extman]#
[root@CentOS7 extman]# yum install mysql-server mysql-client -y
[root@CentOS7 extman]# service mysqld restart
[root@CentOS7 extman]# mysql -uroot < docs/extmail.sql
ERROR 1364 (HY000) at line 31: Field 'ssl_cipher' doesn't have a default value
[root@CentOS7 extman]# vim /etc/my.cnf //把sql_mode参数注释掉
#sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES
[root@CentOS7 extman]# mysql -uroot < docs/extmail.sql
[root@CentOS7 extman]# mysql -uroot < docs/init.sql
导入数据成功后再次修改/etc/my.cnf文件，把刚刚注释的那行给去掉注释，不去掉的话，mysql服务可能会出现不能启动的问题：
[root@CentOS7 extman]# vim /etc/my.cnf
sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES
登陆mysql
[root@CentOS7 extman]# mysql -u root
mysql> GRANT ALL ON extmail.* to extmail@'%' identified by 'extmail';
Query OK, 0 rows affected (0.00 sec)
复制之前的配置文件
[root@CentOS7 extman]# cd /var/www/extsuite/extman/docs/
[root@CentOS7 docs]# cp mysql_virtual_* /etc/postfix/
为extman创建临时目录
[root@CentOS7 docs]# mkdir /tmp/extman
[root@CentOS7 docs]# chown -R postfix.postfix /tmp/extman/
启动postfix、dovecot、saslauthd服务，并查看进程是否正常
