For more details on compiling and installing nginx, please refer to [detailed description of Nginx directory structure and configuration files] and [Nginx installation and deployment]. Here is a simple installation.

Introduction to installing Nginx environment

Operating system:

[root@localhost ~] # cat / etc/redhat-release CentOS Linux release 7.6.1810 (Core) [root@localhost ~] # uname-aLinux localhost.localdomain 3.10.0-957.el7.x86_64 # 1 SMP Thu Nov 8 23:39:32 UTC 2018 x86 "64 GNU/Linux

Nginx software version: nginx-1.17.6.tar.gz

Installation dependency

Note: when compiling and installing, you must install the development tools, otherwise you can't install or report an error.

Rc.local is a boot load file. If you want to add a program to boot in linux, you can generally modify rc.local. This file will be loaded when you boot, so we can use the linux file to set nginx boot self-startup.

[root@localhost ~] # cat / etc/rc.local / / the contents of the rc.local file when the file is stored in / etc directory: #! / bin/bash# THIS FILE IS ADDED FOR COMPATIBILITY PURPOSES## It is highly advisable to create own systemd services or udev rules# to run scripts during boot instead of using this file.## In contrast to previous versions due to parallel execution during boot# this script will NOT be run after all other services.## Please note that you must run 'chmod + x / etc/ Rc.d/rc.local' to ensure# that this script will be executed during boot.touch / var/lock/subsys/local

Using this file, you can set the commands you want to start when you boot, and write the commands you want to execute directly into rc.local.

We add the nginx startup command to this file

[root@localhost ~] # echo sh / usr/local/nginx/sbin/nginx > > / etc/rc.local [root@localhost ~] # cat / etc/rc.local #! / bin/bash# THIS FILE IS ADDED FOR COMPATIBILITY PURPOSES## It is highly advisable to create own systemd services or udev rules# to run scripts during boot instead of using this file.## In contrast to previous versions due to parallel execution during boot# this script will NOT be run after all other services.## Please note that you must run 'chmod + x / etc/rc D / rc.local' to ensure# that this script will be executed during boot.touch / var/lock/subsys/local/usr/local/nginx/sbin/nginx if you set nginx as the system command above, you can write the command directly, nginx.

Then let's restart the system and check the port and process again.

The pid file is the process file in which the process ID that the program is running is stored, that is, the process number

Nginx needs to modify the configuration file to generate the pid file

The modifications are as follows:

The default configuration file has this entry. If not, please find this entry in nginx.conf and delete the previous comments. Pid logs/nginx.pid; adds the nginx.service file under the / usr/lib/systemd/system path.

/ usr/lib/systemd/system this directory is used to store some system services

Contents of nginx file:

[root@localhost system] # cat nginx.service [Unit] Description=nginx / / description After=syslog.target network.target remote-fs.target nss-lookup.target\\ describe service category [Service] Type=forking / / set operation mode Run PIDFile=/usr/local/nginx/logs/nginx.pid / / set PID file ExecStart=/usr/local/nginx/sbin/nginx / / start command ExecReload=/bin/kill-s HUP $MAINPID / / restart command ExecStop=/bin/kill-s QUIT $MAINPID / / close command PrivateTmp=true / / allocate independent temporary space * Note that the command needs to write the absolute path [Install] / related settings for service installation Can be set to multi-user WantedBy=multi-user.target

Note: this file requires 754 permissions

It should be noted that if you use the script to start the service, you cannot use this method to shut down the service.

Set [root@localhost] # systemctl enable nginxCreated symlink from / etc/systemd/system/multi-user.target.wants/nginx.service to / usr/lib/systemd/system/nginx.service. [root@localhost ~] # systemctl enable nginx

Restart to see the effect

Init boot mode is no longer recommended in the centos7 system version.

Create the startup file nginx in the / etc/init.d directory

Services in init.d in centos7 will also be in the system directory by default
