防火墙允许外网访问：

firewall-cmd --zone=public --add-port=22/tcp --peermanent

peermanent：永久

ip addr : 查看网络IP分配情况

centos网络配置：/etc/sysconfig/network-scripts/ifcfg-网卡名称

1.开机启动

ONBOOT=yes

2.静态ip

BOOTPROTO=static：                                             BOOTPROTO=dhcp，动态主机配置协议，我们要做成静态的

IPADDR=192.168.1.150

NETMASK=255.255.255.0

NM_CONTROLLED=no：Network manger服务缺省情况下，不启动，否则修改网卡文件的时候，如果实时生效，可能会导致网络中断

3.重启网络服务

systemctl restart network.service

cmake

如何在Linux下编译安装软件

防火墙开启80端口，

firewall-cmd --zone=public --add-port=80/tcp --permanent

重启防火墙

systemctl restart firewalld.service 

apache使用select轮询，死循环。量大，效率低，占用内存高。

nginx使用epoll监听，效率高，轻便，占用内存低。

linux Apache nginx php  mysql  简介

Nginx与Apache一样是服务器软件，可监听端口、接受请求、解析http/https协议  将用户请求转发给php处理后，将数据返回给apache在递给客户端。

apache 使用的是select 轮循 使用类似for 循环的机制循环查看,对事件, nginx 使用的是yipoor 事件监听,不会玩主动轮循事件,而是监听到改变这进行处理

linux 上安装软件的方式有2种

1.linux上如何编译安装软件 ./configure 编译make 代码编译成二进制文件 安装make install

2. yum安装

yum安装:不下载代码，从远程代码编译安装

设置==》网卡==》桥架网卡==》确定

重启

远程登录，需要打开防火墙

另外设置网路使用桥接网卡
