Detailed steps to install nginx on Linux system

1.Install dependency packages

 //一键安装上面四个依赖
 
 yum -y install gcc zlib zlib-devel pcre-devel openssl openssl-devel

2.Download and unzip Installation package

 //创建一个文件夹
 
 cd /usr/local
 
 mkdir nginx
 
 cd nginx
 
 //下载tar包
 
 wget http://nginx.org/download/nginx-1.13.7.tar.gz
 
 tar -xvf nginx-1.13.7.tar.gz

3. Install nginx

 //进入nginx目录
 
 cd /usr/local/nginx
 
 //进入目录
 
 cd nginx-1.13.7
 
 //执行命令
 
 ./configure
 
 //执行make命令
 
 make
 
 //执行make install命令
 
 make install

4. Configure nginx.conf

 # 打开配置文件
 
 vi /usr/local/nginx/conf/nginx.conf

Change the port The number was changed to 8089 because apeache may occupy port 80. Try not to modify the apeache port. We chose to modify the nginx port.

Change localhost to your server IP address.

5. Start nginx

 /usr/local/nginx/sbin/nginx -s reload

If an error occurs: nginx: [error] open() "/usr/local/ nginx/logs/nginx.pid＂ failed

Run: /usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf

Start again That’s it!

Check whether the nginx process is started:

ps -ef | grep nginx

6. If you want to use an external host to connect Access port 192.168.131.2 on the virtual machine. You need to turn off the firewall of the virtual machine:

centOS6 and previous versions use the command: systemctl stop iptables.service

centOS7 turn off the firewall command: systemctl stop firewalld.service

Then access the ip to see the nginx interface.

7. Access the server IP to check (note, because I am still monitoring port 80, the port number after the IP is omitted)
