• Install nginx

Nginx is a lightweight Web/reverse proxy server and E-mail (IMAP/POP3) proxy server distributed under the BSD-like protocol. In fact, nginx’s concurrent ability is better in the same type of web server. In Mainland China, nginx website users include: Baidu, JINGdong, Sina, netease, Tencent, Taobao, etc.

1. Download nginx

First you need to confirm the installation of the following software
yum -y install gcc pcre-devel zlib-devel openssl openssl-devel

cd /usr/local
mkdir nginx
cd nginx
Download the latest version of NginxWget http://nginx.org/download/nginx-1.16.1.tar.gz tar - ZXVF nginx - 1.16.1. Tar. Gz# copy to nginx folder
cp -r /usr/local/ nginx/nginx - 1.16.1 / * / usr /local/nginx/
./configure
make
make install
Copy the code

• Modify the config

cd conf
vi nginx.conf

Modify the configuration file
# omit the other configuration

http {
    server_tokens off;
    include       mime.types;
    default_type  application/octet-stream;
    #access_log logs/access.log main;
    sendfile        on;
    #tcp_nopush on;

    #keepalive_timeout 0;
    keepalive_timeout  65;

    gzip  on;
    
    Nginx will automatically load all configuration files under enabled-server
    include /usr/local/nginx/enabled-server/*; . }Copy the code

Sometimes we need to deploy more than one site, so we usually create a configuration file named after the site, such as myblog.conf

vi default.conf
# config fileUpstream nodePro {server 127.0.0.1:3000;# project run port number, as the actual change
    keepalive 64;
}

server {
    listen 80; The port number to listen on
    server_name xxxx.com www.xxxx.com; The server name, IP address, or domain name can be multiple, separated by Spaces

    location / {
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Host $http_host;
        proxy_set_header X-Nginx-Proxy true;
        proxy_set_header Connection "";
        proxy_pass http://nodepro; Upstream (" upstream ")}}Copy the code

• Check whether the nginx configuration is successful

cd. ./nginx -t# change succeeded
nginx: the configuration file /www/server/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /www/server/nginx/conf/nginx.conf test is successful
Copy the code

• Start the nginx server

./nginx
Copy the code
