1. Version difference

Commonly used versions are divided into four camps

• Nginx open source version http://nginx.org/
• Nginx plus commercial version https://www.nginx.com
• openresty http://openresty.org/cn/
• Tengine http://tengine.taobao.org/

2. Compile and install

nginx installation package:

The version 1-21.6 is installed here, and the tar.gz compressed package is transferred to the virtual machine and decompressed

tar -zxvf nginx-1.21.6.tar.gz

After installing gcc and related dependencies

yum install - y gcc

yum install - y pcre pcre - devel # install perl library

yum install - y zlib zlib - devel  # Install the zlib library

official installation

// After entering the nginx-1.21.6 directory, you can see the configure configuration file and install it through it

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

make

make install

3. Start nginx

Enter the installed directory /usr/local/nginx/sbin

./nginx start

./nginx -s stop quick stop

./nginx -s quit graceful shutdown, complete the accepted connection request before exiting

./nginx -s reload reload configuration

After startup, you can access nginx through the ip address, and you can see that the default access page appears, and nginx is installed successfully.

About the firewall

The access timeout may be because the firewall is not closed

turn off firewall

systemctl stop firewalld.service

Disable the firewall from booting

systemctl disable firewalld.service release port

firewall - cmd -- zone=public -- add - port=80/tcp -- permanent

restart firewall

firewall - cmd -- reload

4. Install as a system service

It is too troublesome to start nginx under /usr/local/nginx/sbin every time. How to implement systemctl start nginx.service to start nginx

Create service script

vi /usr/lib/systemd/system/nginx.service
