Basic overview
Nginx is the mainstream Internet high-performance HTTP and echo proxy Web server, Nginx can not only serve as a Web server, it also provides static resource service, cache, load balancing and other functions.
Whether you’re a front-end programmer or a back-end programmer, you’re probably familiar with Nginx. It acts as a bridge between the front end and the back end, acting as a kind of glue. Especially in the era of separation of the front and back ends, Nginx appears as often as a-list idol stars. In the age of Cloud Native, the advent of the Envoy seems to enhance our chances of technological selection. Of course both Envoy and Nginx use the multi-threaded + non-blocking + asynchronous IO (Libevent) architectural pattern.
Build Nginx
Deploy Nginx based on Centos 7
- Install nginx-related dependencies
#Install nginx to support rewrite
yum -y install pcre*
#Install nginx to support GCC-C ++
yum -y install gcc-c++
#Install nginx to support Zlib
yum -y install zlib*
#Install nginx to support OpenSSL
yum -y install openssl

Copy the code- Configure Nginx startup upon startup
[1]. Create nginx.service in /lib/systemd/system/ directory:
[Unit]
Description=nginx
After=network.target
[Service]
Type=forking
ExecStart=/usr/local/nginx/sbin/nginx
ExecReload=/usr/local/nginx/sbin/nginx -s reload
ExecStop=/usr/local/nginx/sbin/nginx -s quit
PrivateTmp=true
[Install]
WantedBy=multi-user.target
Copy the code[Notes]: [Unit]: Description of the Service Description: describes the Service After: describes the Service category. [Service] Setting the Service running parameters. Type:forking is the background running mode ExecStop is a stop command PrivateTmp:True Specifies an independent temporary space for the Service. All commands for starting, restarting, and stopping a Service require the absolute path [Install]
[2]. Add automatic system startup
#Setting boot
systemctl enable nginx.service
#Start the nginx service
systemctl start nginx.service
#Check the nginx service status
systemctl status nginx.service
#Restarting the service
systemctl restart nginx.service
#View all services that have been started
systemctl list-units --type=service
