技術標籤：linuxnginxnginx的安裝

一，nginx的安裝
1.安裝包管理工具

yum install yum-utils

2.在/etc/yum.repos.d/nginx.repo下寫

[nginx-stable]
name=nginx stable repo
baseurl=http://nginx.org/packages/centos/$releasever/$basearch/
gpgcheck=1
enabled=1
gpgkey=https://nginx.org/keys/nginx_signing.key
module_hotfixes=true

[nginx-mainline]
 

name=nginx mainline repo
baseurl=http://nginx.org/packages/mainline/centos/$releasever/$basearch/
gpgcheck=1
enabled=0
gpgkey=https://nginx.org/keys/nginx_signing.key
module_hotfixes=true

3.檢視是否成功

yum list nginx

4.安裝

yum -y install nginx

二，nginx的相關操作
1.配置web伺服器的核心檔案/etc/nginx/nginx.conf

user  nginx; #使用者
worker_processes  1;
 
#取決於cpu核心數

error_log  /var/log/nginx/error.log warn;#錯誤日誌
pid        /var/run/nginx.pid;    #主程序pid


events {
    worker_connections  1024;
}

#伺服器核心配置
http {
    include       /etc/nginx/mime.types;
    default_type  application/octet-stream;

    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
 

                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

    access_log  /var/log/nginx/access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    keepalive_timeout  65;

    #gzip  on;
	#引入子配置檔案，位置為/etc/nginx/conf.d
    include /etc/nginx/conf.d/*.conf;
}

2.網站的核心配置在/etc/nginx/conf.d 裡面

3.啟動nginx

systemctl start nginx

4.檢視nginx執行狀態

systemctl status nginx

5.檢視nginx程序

ps aux | grep nginx

6.nginx的語法檢測與重啟
6.1語法檢測

nginx -t

6.2重啟

systemctl reload nginx

7.nginx的操作
7.1快速關機

nginx -s stop

7.2正常關機

nginx -s quit

三，防火牆，nginx啟動後用ip去訪問如果無法訪問就是和防火牆有關係
1使用命令檢視

systemctl status firewalld

3.開啟防火牆

systemctl start firewalld.service

4.重啟防火牆

systemctl restart firewalld.service

5.檢視firewall防火牆的狀態

firewall-cmd --state

6.檢視防火牆開放埠規則

firewall-cmd --list-port

7.檢視80埠是否開啟

firewall-cmd --query-port=80/tcp

8.開放80埠

firewall-cmd --permanent --add-port=80/tcp  #（–permanent永久生效，沒有此引數重啟後就失效）

9.載入生效開放的埠
每次修改防火牆，或者修改埠都需要用下面的命令重啟防火牆

firewall-cmd --reload

10.查詢指定埠80是否開放

firewall-cmd --query-port=80/tcp
