1.連接服務(wù)器

1. Ssh root@服務(wù)器地址連接遠(yuǎn)程服務(wù)器
2. Uname -a顯示服務(wù)器信息
3. log out 退出服務(wù)器

2.web服務(wù)器

1. nginx
2. apache
3. tomcat php

2.1 安裝nginx

yum install nginx

2.2 配置服務(wù)器

user nginx -> user root
http server location

nginx -t

nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful

vim /etc/nginx/nginx.conf

:set nu vim模式下出現(xiàn)行號

3. 上傳服務(wù)到服務(wù)器

使用scp命令scp -r ./* root@ip:/root/www
服務(wù)器端和本地都要有scpyum install openssh-cli

ps -ef | grep nginx查看一下當(dāng)前再跑的進(jìn)程

3.出問題了

因為服務(wù)器的ip發(fā)生變更了
第一次SSH連接時细燎，會生成一個認(rèn)證，儲存在客戶端（也就是用SSH連線其他電腦的那個，自己操作的那個）中的known_hosts倍踪，但是如果服務(wù)器驗證過了清焕，認(rèn)證資訊當(dāng)然也會更改矛紫，服務(wù)器端與客戶端不同時仁热，就會跳出錯誤啦耙厚。

解決辦法：刪除留存的秘鑰

輸入命令：ssh-keygen -R +輸入服務(wù)器的IP
例如：
 ~  ssh-keygen -R 192.168.198.147                                                                                                                                                                ?
# Host 192.168.198.147 found: line 36
/Users/renwoxing/.ssh/known_hosts updated.
