防火墻允許外網訪問：

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

peermanent：永久

ip addr : 查看網絡IP分配情況

centos網絡配置：/etc/sysconfig/network-scripts/ifcfg-網卡名稱

1.開機啟動

ONBOOT=yes

2.靜態ip

BOOTPROTO=static：???????? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? BOOTPROTO=dhcp，動態主機配置協議，我們要做成靜態的

IPADDR=192.168.1.150

NETMASK=255.255.255.0

NM_CONTROLLED=no：Network manger服務缺省情況下，不啟動，否則修改網卡文件的時候，如果實時生效，可能會導致網絡中斷

3.重啟網絡服務

systemctl restart network.service

cmake

如何在Linux下編譯安裝軟件

防火墻開啟80端口，

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

重啟防火墻

systemctl restart firewalld.service?

apache使用select輪詢，死循環。量大，效率低，占用內存高。

nginx使用epoll監聽，效率高，輕便，占用內存低。

linux Apache nginx php ?mysql ?簡介

Nginx與Apache一樣是服務器軟件，可監聽端口、接受請求、解析http/https協議 ?將用戶請求轉發給php處理后，將數據返回給apache在遞給客戶端。

apache 使用的是select 輪循 使用類似for 循環的機制循環查看,對事件, nginx 使用的是yipoor 事件監聽,不會玩主動輪循事件,而是監聽到改變這進行處理

linux 上安裝軟件的方式有2種

1.linux上如何編譯安裝軟件 ./configure 編譯make 代碼編譯成二進制文件 安裝make install

2. yum安裝

yum安裝:不下載代碼，從遠程代碼編譯安裝
