Install Nginx on Linux (Centos7)

1. Compile and install the offline installation package

1. Upload the nginx compressed package to the server/opt directory via Xftp

2. Unzip to /usr/local/

tar -zxvf nginx-1.14.2.tar.gz -C /usr/local/

3. Install dependencies

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

4. Enter the nginx root directory and execute ./configure

./configure

5. Execute make, and continue to execute make install after completion

1. make
2. make install

6. Enter the /usr/local/nginx/sbin directory, enter ./nginx to start nginx, and check whether there is an nginx process

./nginx

7. Browser access test (IP: port)

1. Close the firewall or open the firewall port (nginx defaults to port 8080), choose one

//1. 关闭防火墙
1. systemctl stop firewalld 

//2. 防火墙开放8080端口
1. firewall-cmd --zone=public --add-port=8080/tcp --permanent
2. systemctl restart firewalld   //重启

2. Browser access

Set up autostart

1. Create a new system service file (nginx.service), and write the following content into the file

vim /etc/systemd/system/nginx.service

[Unit]
Description=nginx service
After=network.target

[Service]
Type=forking
#确认下路径，如果不是在/usr/local则需改成对应路径
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

2. Set Nginx to start automatically after booting, and execute in sequence

1. chmod 755 /etc/systemd/system/nginx.service  //授权
2. systemctl daemon-reload           //加载配置
3. systemctl enable nginx            //设置开机自启

3. Start the Nginx service

systemctl start nginx

4. Other common commands

systemctl status nginx   //查看nginx状态
systemctl stop nginx     //关闭nginx
systemctl restart nginx  //重启nginx

Two, yum installation

1. Install nginx source

rpm -Uvh http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm

2. Use yum to install nginx

yum install -y nginx

3. Start nginx and check the startup status

1. systemctl start nginx  //启动nginx
2. systemctl status nginx //查看nginx状态

4. Browser access test (IP: port)
1. Close the firewall or open the firewall port (nginx default port 8080), choose one

//1. 关闭防火墙
1. systemctl stop firewalld 

//2. 防火墙开放8080端口
1. firewall-cmd --zone=public --add-port=8080/tcp --permanent
2. systemctl restart firewalld   //重启

2. Browser access

Check the version and the path of each file

1. View version

nginx -v

2. View the path of each file

1. rpm -qa | grep nginx
2. rpm -ql nginx-1.22.1-1.el7.ngx.x86_64

Precautions

1. Configuration file
* change as needed tonginx.conf

/etc/nginx/conf.d/default.conf

2. Replace the port
*Pay attention to closing SELinux, otherwise there may be problems starting

------1. Temporarily close SELinux

 setenforce 0

------2. Permanently closed

1. SELINUX=enforcing Change toSELINUX=disable

 vim /etc/selinux/config

2. Restart the system

reboot
