CentOS7安装Nginx

一、安装依赖

yum -y install gcc gcc-c++ make libtool zlib zlib-devel openssl openssl-devel pcre pcre-devel

二、下载Nginx

1.官网直接下载.tar.gz安装包，地址：nginx: download

2.使用wget命令下载

wget -c https://nginx.org/download/nginx-1.22.1.tar.gz

三、解压

tar -zxvf nginx-1.22.1.tar.gz
cd nginx-1.22.1

四、配置

1. 不需要SSL

   ./configure --prefix=/usr/local/nginx
   

2. 需要SSL

   ./configure --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module
   

五、编译安装

make
make install

六、启动Nginx

# 启动
cd /usr/local/nginx/sbin/
./nginx 
 
# 重启
./nginx -s reload

七、Nginx配置

1. nginx.conf配置

   user  root;
   worker_processes  1;
   
   error_log  /usr/local/nginx/logs/error.log warn;
   #pid        /var/run/nginx.pid;
   
   events {
       worker_connections  1024;
   }
   
   http {
       include       /usr/local/nginx/conf/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  /usr/local/nginx/logs/access.log  main;
   
       sendfile        on;
       #tcp_nopush     on;
   
       keepalive_timeout  65;
   
       #gzip  on;
       gzip  on;
       gzip_min_length 1k;
       gzip_buffers 4 16k;
       gzip_comp_level 3;
       gzip_types text/plain text/css application/xml application/javascript application/x-javascript text/javascript;
       include /usr/local/nginx/conf/conf.d/*.conf;
   }
   

2. default.http.conf配置

   server {
       listen       80;
       server_name  xxx.cn www.xxx.cn;
       client_max_body_size 150M;
   
       location / {
           root   /home/busapp/ui/;
           #index  index.html;
           # 解决vue打包项目后刷新404的问题
           try_files $uri $uri/ /index.html =404; 
       }
       location /api/ {
           proxy_pass http://127.0.0.1:27071/;
           proxy_redirect              off;
           proxy_set_header            Host $host;
           proxy_set_header            X-Real-IP $remote_addr;
           proxy_set_header            X-Forwarded-For $proxy_add_x_forwarded_for;
           proxy_set_header Upgrade $http_upgrade;
           proxy_set_header Connection "upgrade";
           proxy_connect_timeout 60s;
           proxy_read_timeout 60s;
           proxy_send_timeout 60s;
       }
       location /ptapi/ {
           proxy_pass http://127.0.0.1:27071/;
           proxy_redirect              off;
           proxy_set_header            Host $host;
           proxy_set_header            X-Real-IP $remote_addr;
           proxy_set_header            X-Forwarded-For $proxy_add_x_forwarded_for;
           proxy_set_header Upgrade $http_upgrade;
           proxy_set_header Connection "upgrade";
           proxy_connect_timeout 60s;
           proxy_read_timeout 60s;
           proxy_send_timeout 60s;
       }
       error_page   500 502 503 504  /50x.html;
       location = /50x.html {
           root   html;
       }
   }
   

3. 配置SSL证书

   # 创建证书目录
   cd /usr/local/nginx/
   mkdir cert
   

   server {
       listen 443 ssl;
       server_name  xxx.cn www.xxx.cn;
   
       ssl_certificate      /usr/local/nginx/7369597_xxx.cn.pem;
       ssl_certificate_key  /usr/local/nginx/7369597_xxx.cn.key;
   
       ssl_session_cache    shared:SSL:1m;
       ssl_session_timeout  5m;
   
       root   /home/busapp/ui/;
       index  index.html;
       ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:ECDHE:ECDH:AES:HIGH:!NULL:!aNULL:!MD5:!ADH:!RC4;
       ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
       ssl_prefer_server_ciphers on;
       client_max_body_size 50M;
       location /api/ {
           proxy_pass http://127.0.0.1:27071/;
           proxy_redirect              off;
           proxy_set_header            Host $host;
           proxy_set_header            X-Real-IP $remote_addr;
           proxy_set_header            X-Forwarded-For $proxy_add_x_forwarded_for;
           proxy_set_header Upgrade $http_upgrade;
           proxy_set_header Connection "upgrade";
           proxy_connect_timeout 60s;
           proxy_read_timeout 60s;
           proxy_send_timeout 60s;
       }
       location /ptapi/ {
           proxy_pass http://127.0.0.1:27071/;
           proxy_redirect              off;
           proxy_set_header            Host $host;
           proxy_set_header            X-Real-IP $remote_addr;
           proxy_set_header            X-Forwarded-For $proxy_add_x_forwarded_for;
           proxy_set_header Upgrade $http_upgrade;
           proxy_set_header Connection "upgrade";
           proxy_connect_timeout 60s;
           proxy_read_timeout 60s;
           proxy_send_timeout 60s;
       }
       error_page   500 502 503 504  /50x.html;
       location = /50x.html {
           root   html;
       }
   }
   
   

八、设置开机自启

1. 在rc.local增加启动代码就可以了。

   vim /etc/rc.local
   

   增加一行 /usr/local/nginx/sbin/nginx

   

2. 设置执行权限

   chmod 755 rc.local
   

   到这里，nginx就安装完毕了。

九、卸载Nginx

1. 卸载Nginx

   yum remove nginx
   

2. 查看Nginx是否还存在

   which nginx
