ubuntu下使用xinetd

【前沿及知识点】
标准http响应文件内容
HTTP/1.1 200 OK
Server: Apache-Coyote/1.1
Content-Length: 0
Date: Wed, 27 Feb 2013 02:34:36 GMT

ubuntu下安装
apt-get install xinetd

【创建个服务脚本】
/root/shell/httpok.sh

#!/bin/sh

/bin/echo -e "HTTP/1.1 200 OK\r\n"
/bin/echo -e "Content-Type: Content-Type: text/plain\r\n"
/bin/echo -e "\r\n"
/bin/echo -e "hello xinetd\r\n"
/bin/echo -e "\r\n"

修改脚本权限(给user执行权限)
chmod 755 /etc/xinetd.d/httpok

【创建xinetd服务】
vi /etc/xinetd.d/httpok
service my_httpok
{
    flags           = REUSE
    socket_type     = stream
    #port            = 9201
    wait            = no
    user            = root
    server          = /root/shell/httpok.sh
    #log_on_failure  += USERID
    disable         = no
    #only_from       = 192.168.5.0/24
    #recommended to put the IPs that need to connect exclusively (security purposes)
}


【修改端口，方法有2种】
1.默认依赖/etc/services，此时/etc/xinetd.d/httpok这个文件配置的port无效，所以不需要配置
vi /etc/services
my_httpok            9201/tcp

2.解除依赖/etc/services
此时/etc/xinetd.d/httpok这个文件配置里需要加上
type            = UNLISTED
port            = 9201

【重启服务,测试端口访问】
service xinetd restart
curl http://127.0.0.1:9201/
