xinetd 配置转发

实验环境：

mysql:192.168.6.90  3306

xinetd:192.168.6.91 9001

实验目的：

通过访问 192.168.6.91:9001 连接 192.168.6.90:3306 数据库

在 192.168.6.91配置

#安装xinetd
yum  -y  install  xinetd*    

#设置开机自启
systemctl  enable  xinetd.service

建立要转发的配置文件：

vim /etc/xinetd.d/mysql


service mysql
{
    per_source = UNLIMITED
    instances = UNLIMITED  #这两行为去掉连接limit限制
  
    disable = no
    type = UNLISTED
    socket_type = stream
    protocol = tcp
    wait = no
    redirect = 192.168.6.90  3306
    bind = 0.0.0.0
    only_from = 192.168.6.0/24 192.168.10.235 192.168.5.159
    port = 9001
    user = root
    flags = NODELAY KEEPALIVE NOLIBWRAP IPv4
    log_type = FILE /var/log/mysql-test.log
    cps = 100 30
}

启动xinetd服务

systemctl restart xinetd.service
