One , Compilation and installation Nginx service

1. Configuration environment

Turn off firewall , Will install nginx The required software package is transferred to /opt Under the table of contents

systemctl stop firewalld
systemctl disable firewalld
setenforce 0

2. Install dependency packages

nginx The configuration and operation of pcre、zlib And so on , Therefore, you need to install the development package of these software , In order to provide the corresponding library and header file

yum -y install pcre-devel zlib-devel gcc gcc-c++ make

3. Create a running user 、 Group

（Nginx The service program defaults to nobody Identity running , It is recommended to create a special user account for it , In order to more accurately control its access rights ）

useradd -M -s /sbin/nologin nginx

4. Compilation and installation Nginx

tar zxvf nginx-1.12.2.tar.gz -C /opt

cd /opt/nginx-1.12.2/
./configure \
--prefix=/usr/local/nginx \
--user=nginx \
--group=nginx \
--with-http_stub_status_module
# Appoint nginx The installation path 
# Specify user name 
# Specify the group name 
# Enable  httpd_stub_status_module  Module to support State Statistics 


make -j 4 && make install

ln -s /usr/local/nginx/sbin/nginx /usr/local/sbin/
# Optimize the path , Let the system recognize nginx Operation command of 

5. add to Nginx system service

vim /etc/init.d/nginx
