1 安裝yum-utils

使用yum進行安裝

yum install yum-utils -y

---

2 配置Nginx的yum源

創建相應的配置文件

vi /etc/yum.repos.d/nginx.repo

沒有vim的先安裝 yum install vim -y

寫入配置並保存

[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

enabled=1爲需要安裝的版本，默認爲stable版本，可以使用yum命令切換

# 切換到mainline
yum-config-manager --enable nginx-mainline

# 切換到stable
yum-config-manager --enable nginx-stable

---

3 安裝並配置Nginx

安裝

yum install nginx -y

啓動服務並輸入網址檢查是否安裝成功

#重載守護進程
systemctl daemon-reload
#查看服務狀態
systemctl status nginx
#啓動服務
systemctl start nginx
#停止服務
systemctl stop nginx
#重啓服務
systemctl restart nginx
#開機自啓動
systemctl enable nginx
#取消自啓動
systemctl disable nginx

如果成功可以看到

systemctl status nginx查看服務狀態，可以看到配置文件所在位置

 nginx.service - nginx - high performance web server
   Loaded: loaded (/usr/lib/systemd/system/nginx.service; enabled; vendor preset: disabled)
   Active: active (running) since Sat 2020-01-18 16:21:09 HKT; 13min ago
     Docs: http://nginx.org/en/docs/

   CGroup: /system.slice/nginx.service
           ├─34373 nginx: master process /usr/sbin/nginx -c /etc/nginx/nginx.conf
           └─34374 nginx: worker process

Jan 18 16:21:09 localhost.localdomain systemd[1]: Starting nginx - high performance web server...
Jan 18 16:21:09 localhost.localdomain systemd[1]: Started nginx - high performance web server.

上面看到的配置文件是/etc/nginx/nginx.conf

# 查看配置的命令
cat /etc/nginx/nginx.conf

#配置文件如下

user  nginx;
worker_processes  1;

error_log  /var/log/nginx/error.log warn;
pid        /var/run/nginx.pid;


events {
    worker_connections  1024;
}


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;
    # 此處可以看到配置文件所在目錄
    include /etc/nginx/conf.d/*.conf; 
}

查看配置文件所在目錄

ls /etc/nginx/conf.d/

#只有一個默認配置文件
default.conf

修改配置

vi /etc/nginx/conf.d/default.conf
