A） Nginx.conf中添加：
location /extmail/cgi/ {
fastcgi_pass 127.0.0.1:8888;
include conf/fcgi.conf;
}
location /extmail/ {
alias /var/www/extsuite/extmail/html/;
}
location /extman/cgi/ {
fastcgi_pass 127.0.0.1:8888;
include conf/fcgi.conf;
}
location /extman/ {
alias /var/www/extsuite/extman/html/;
}
B）编辑conf/fcgi.conf内容：（nginx的conf目录下新建fcgi.conf）
#fastcgi.conf
fastcgi_param GATEWAY_INTERFACE CGI/1.1;
fastcgi_param SERVER_SOFTWARE nginx;
fastcgi_param QUERY_STRING $query_string;
fastcgi_param REQUEST_METHOD $request_method;
fastcgi_param CONTENT_TYPE $content_type;
fastcgi_param CONTENT_LENGTH $content_length;
fastcgi_param SCRIPT_NAME $fastcgi_script_name;
fastcgi_param REQUEST_URI $request_uri;
fastcgi_param DOCUMENT_ROOT $document_root;
fastcgi_param SERVER_PROTOCOL $server_protocol;
fastcgi_param REMOTE_ADDR $remote_addr;
fastcgi_param REMOTE_PORT $remote_port;
fastcgi_param SERVER_ADDR $server_addr;
fastcgi_param SERVER_PORT $server_port;
fastcgi_param SERVER_NAME $server_name;
编辑保存.
重启动nginx，然后启动dispatch-init
extmail在nginx下的配置完成
