Install nginx on centos7 system and configure the startup operation

The preparatory work

My centos7 system is minimally installed and lacks a lot of libraries. First, install the necessary runtime libraries

yum install wget gcc gcc-c++ pcre-devel zlib-devel
## Create the working directory and enter the working directory 
mkdir -p /z/nginx && cd /z/nginx
## To obtain nginx Latest installation package 
wget http://nginx.org/download/nginx-1.11.10.tar.gz
## unzip 
tar zxvf nginx-1.11.10.tar.gz
## Enter the directory 
cd nginx-1.11.10
## Detection system configuration ,  generate make The relevant documents 
./configure

Successful execution of./configure outputs the following information

Where nginx is installed, and the file path

Configuration summary
 + using system PCRE library
 + OpenSSL library is not used
 + using system zlib library
 nginx path prefix: "/usr/local/nginx"
 nginx binary file: "/usr/local/nginx/sbin/nginx"
 nginx modules path: "/usr/local/nginx/modules"
 nginx configuration prefix: "/usr/local/nginx/conf"
 nginx configuration file: "/usr/local/nginx/conf/nginx.conf"
 nginx pid file: "/usr/local/nginx/logs/nginx.pid"
 nginx error log file: "/usr/local/nginx/logs/error.log"
 nginx http access log file: "/usr/local/nginx/logs/access.log"
 nginx http client request body temporary files: "client_body_temp"
 nginx http proxy temporary files: "proxy_temp"
 nginx http fastcgi temporary files: "fastcgi_temp"
 nginx http uwsgi temporary files: "uwsgi_temp"
 nginx http scgi temporary files: "scgi_temp"

Compile and install

make && make install

Create the nginx launch command script

vi /etc/init.d/nginx

Insert the following and be careful to modify the PATH and NAME fields to match your own installation path (this is from copy on the web)

#! /bin/bash
# chkconfig: - 85 15
PATH=/usr/local/nginx
DESC="nginx daemon"
NAME=nginx
DAEMON=$PATH/sbin/$NAME
CONFIGFILE=$PATH/conf/$NAME.conf
PIDFILE=$PATH/logs/$NAME.pid
SCRIPTNAME=/etc/init.d/$NAME
set -e
[ -x "$DAEMON" ] || exit 0
do_start() {
$DAEMON -c $CONFIGFILE || echo -n "nginx already running"
}
do_stop() {
$DAEMON -s stop || echo -n "nginx not running"
}
do_reload() {
$DAEMON -s reload || echo -n "nginx can't reload"
}
case "$1" in
start)
echo -n "Starting $DESC: $NAME"
do_start
echo "."
;;
stop)
echo -n "Stopping $DESC: $NAME"
do_stop
echo "."
;;
reload|graceful)
echo -n "Reloading $DESC configuration..."
do_reload
echo "."
;;
restart)
echo -n "Restarting $DESC: $NAME"
do_stop
do_start
echo "."
;;
*)
echo "Usage: $SCRIPTNAME {start|stop|reload|restart}" >&2
exit 3
;;
esac
exit 0

Set execution permissions

chmod a+x /etc/init.d/nginx

Register as service

chkconfig --add nginx

Set to boot

chkconfig nginx on

Restart to see if the nginx service starts automatically

shutdown -h 0 -r
netstat -apn|grep nginx

Perform stop/start/re-read configuration file operations on the nginx service

# Start the nginx service 
systemctl start nginx.service
# stop nginx service 
systemctl stop nginx.service
# restart nginx service 
systemctl restart nginx.service
# reread nginx configuration ( This is the most commonly used ,  Don't stop nginx The service enables the modified configuration to take effect )
systemctl reload nginx.service
