1, after the environment is ready, download the installation package
Enter a directory (just a directory can be used to store the downloaded installation package Nginx, here in the / root directory, for example)
Enter the directory command: cd / root
Nginx download the installation package, this use case nginx-1.16.0 (latest version is available through the official website - http://nginx.org/download to view )
Download command: wget http://nginx.org/download/nginx-1.16.0.tar.gz
2，解压Nginx的tar包Unzip command: tar -zxvf ./nginx-1.16.0.tar.gz
3, to see if decompression success
Command: ls
4, into the newly unpacked directory
Command: cd nginx-1.16.0
Configuration (in this case the mounting point Nginx / usr / local / nginx / directory)
命令: ./configure --prefix=/app/nginx/
5, compile and install
命令: make && make install
6, the entire verification, compilation, the installation process should not report anything wrong, if you use the prefix set in a target directory during installation, you also need to set the environment variable in the / etc / profile file (Note: The environment variable generally refers to operating system is used to specify the parameters of the operating system environment, the software equivalent of a boot is provided (e.g. mysql / jdk) fast path, etc., user-friendly.)
Command: vi / etc / profile
In most added at the end of export PATH = / app / nginx / sbin: $ PATH (where # add nginx path to comment suggested adding)
7, so that the environment variables to take effect
Command: source / etc / profile
8, with the export command to view the environment variables found to have just set up Nginx directory has been successfully into the
9, check whether the installation was successful:
Into the etc directory (cd / etc) execute the command: nginx -t, if correct will be given the appropriate error message
10, Nginx configuration file to configure the location Nginx configuration file: /app/nginx/conf/nginx.conf (exact location depends on your own if you do not know where to put the configuration file, you can use xftp view) , using vi command editing:
we /usr/local/nginx/conf/nginx.conf
11, the configuration file to modify the configuration files are installed in the conf directory nginx.conf, command Nginx:
/usr/local/nginx/sbin/nginx -c /app/nginx/conf/nginx.conf
12, start nginx, command:
nginx
13, see the Nginx status command:
ps -ef | grep nginx
14 test, in the case of an externally accessible start Nginx browser address just configured in the configuration file, as shown, that is success
Problems that may arise:
When using an external browser, access the address is likely not to visit.
Cause of the problem: There is no open port 80, or a firewall is not closed
For security reasons, it is recommended to select 80 ports open
1, open port 80 (please note that at this time to make sure the firewall is turned on. Otherwise, this step does not make sense):
Command to view open ports in the firewall - iptables -L
A port (80 in this example) open firewall-cmd --zone = public --add-port = 80 / tcp --permanent
Restart the firewall: systemctl restart firewalld.service
2, turn off the firewall:
service firewalld stop
These two operations, one to select. So far, Nginx installation tutorial.
In nginx compiled nginx.conf installation package file as follows:
http {
upstream ipv6 {# ipv6 is the name of the upstream server to create their own
server 1.1.1.1:80; # 1.1.1.1 is the IP address of the real site of IPv4
}
……
……
……
server {
listen 80 default_server ;
listen [::]:80 default_server ; #增加该命令，即监听所有IPv6的80端口
server_name xxxx.yyyy.edu.cn; #IPv4的url……
……
……
location / {
proxy_pass http://ipv6; #该部分所有的红颜色为添加的，需要关联upstream和server信息
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
root html;
index index.html index.htm;
}After installation, enable nginx service, you can be tested.
Add plurality of agents as follows:
http {
map $host $upstream{

www.bbbb.edu.cn 2.2.2.2:80;
