Nginx 1.14.2 Porting Guide (openEuler 20.03 LTS SP1)

randy15682021-12-29NginxPorting Guide

Introduction

Nginx Overview

Nginx is a lightweight web server that can act as a reverse proxy or mail (IMAP/POP3) proxy. It provides high concurrency with a low memory footprint, and supports FastCGI, SSL, virtual hosts, URL rewriting, gzip, and extension of many third-party modules.

Programming language: C

Configuring the Compilation Environment

Configuring the Yum Repository

NOTE: Configure the local source if the server cannot obtain dependencies from the Internet using yum commands.

  1. Copy the OS image file openEuler-20.03-LTS-everything-aarch64-dvd.iso to the /root directory on each server.

  2. Mount the image file. Mount the openEuler .iso file in the /root directory to the /mnt directory.

    mount /root/openEuler-20.03-LTS-SP1-everything-aarch64-dvd.iso /mnt

    NOTE: This operation takes effect only once and becomes invalid after the OS is restarted. (Optional) To configure automatic image mounting on boot, perform the following steps:

    (1) Open the fstab file.
    vi /etc/fstab

    (2) Add the following content to the end of the fstab file:
    /root/openEuler-20.03-LTS-SP1-everything-aarch64-dvd.iso /mnt iso9660 loop 0 0

    (3) Save and then exit the fstab file.

  3. Add a local source file.

    (1) Go to the /etc/yum.repos.d directory.

    cd /etc/yum.repos.d

    NOTE: It is recommended that you move the *.repo file in this directory to any other backup directory.

    (2) Create a local.repo file.

    ​ a. Open the local.repo file.
    vi local.repo

    ​ b. Add the following content to the local.repo file:

    [local]
    name=local.repo
    baseurl=file:///mnt
    enabled=1
    gpgcheck=0
    

    NOTE: The file path in baseurl is the image-mounting path, which corresponds to image file mounting directory /mnt.

    ​ c. Save and exit the local.repo file.

    ​ d. Make sure the local source is used.

    yum clean all
    yum makecache
    yum list
    

Installing Dependencies

Download and install dependencies.

yum -y install gcc gcc-c++ make libtool zlib zlib-devel pcre pcre-devel pcre2-devel perl-devel perl-ExtUtils-Embed openssl openssl-devel

Obtaining the Source Code

This document uses the source code for compilation and installation. You will also need to obtain the Nginx source code.

Run the following commands to download the Nginx source code:

cd /home

wget https://nginx.org/download/nginx-1.14.2.tar.gz --no-check-certificate

NOTE: You can also download the source code using a local browser and upload it to the /home directory on the server. Download address: https://nginx.org/download/nginx-1.14.2.tar.gz

NOTE: If you need to configure a proxy to access the Internet, perform the following operations.

  1. Open the profile file.
    vi /etc/profile
  2. Add the following code, and then save the file and exit. The user name, password, IP address, and port number of the proxy server must be configured based on the site requirements.
export http_proxy="http://Proxy server user name:password@IP address:port"
export http_proxy=$http_proxy
export no_proxy=127.0.0.1,.huawei.com,localhost,local,.local
  1. Ensure the proxy is used.
    source /etc/profile
  2. View the proxy information in the environment variables.
    env
  3. Verify whether the proxy function is configured successfully.
    curl www.baidu.com

If Baidu, for example, can be parsed, the configuration is successful.

Compiling and Installing Nginx

  1. Decompress the Nginx installation package.
    tar -xvf nginx-1.14.2.tar.gz

  2. Go to the nginx-1.14.2 directory.
    cd /home/nginx-1.14.2/

  3. Configure Nginx.
    ./configure --prefix=/usr/local/nginx --with-http_ssl_module NOTE:

  • --prefix=PATH specifies the Nginx installation directory. The default installation directory is /usr/local/nginx.
  • with-http_stub_status_module does not need to be configured because this module affects the performance of Nginx.
  1. Compile and install Nginx.

make -j96 && make -j96 install

NOTE: In the command, -j96 leverages the multi-core feature of the CPUs to accelerate compilation. You can run the lscpu command to query the number of CPU cores.

  1. Check the installation directory.

ls /usr/local/nginx

Running and Verifying Nginx

Generating a Certificate

  1. Go to the /usr/local/nginx directory and generate a key in the directory.
    cd /usr/local/nginxopenssl genrsa -des3 -out server_2048.key 2048

Enter a password twice. The server_2048.key file is generated.

[root@localhost nginx]# openssl genrsa -des3 -out server_2048.key 2048
Generating RSA private key, 2048 bit long modulus (2 primes)
..................................................................................+++++
................+++++
e is 65537 (0x010001)
Enter pass phrase for server_2048.key:
Verifying - Enter pass phrase for server_2048.key:

NOTE: You can run the following command to use the file without needing a password:
openssl rsa -in server_2048.key -out -server_2048.key

[root@localhost nginx]# openssl rsa -in server_2048.key -out -server_2048.key
Enter pass phrase for server_2048.key
writing RSA key
  1. Create a certificate signing request (CSR).
openssl req -new -key server_2048.key -out server_2048.csr
[root@localhost nginx]# openssl req -new -key server_2048.key -out server_2048.csr
You are about to be asked to enter information that will be incorporated
into your certificate request.
What you are about to enter is what is called a Distinguished Name or a DN.
There are quite a few fields but you can leave some blank
For some fields there will be a default value,
If you enter '.', the field will be left blank.
Country Name (2 letter code) [AU]:CN
State or Province Name (full name) [Some-State]:
Locality Name (eg, city) []:
Organization Name (eg, company) [Internet Widgits Pty Ltd]:
Organizational Unit Name (eg, section) []:
Common Name (e.g. server FQDN or YOUR name) []:
Email Address []:

Please enter the following 'extra' attributes
to be sent with your certificate request
A challenge password []:
An optional company name []:

Enter the password set in 1. Set Country Name to CN, for example, and leave other parameters blank.
3. Rewrite the key.
openssl rsa -in server_2048.key -out server_2048.key

[root@localhost nginx]# openssl rsa -in server_2048.key -out server_2048.key
writing RSA key
  1. Generate a certificate.
    openssl x509 -req -days 365 -in server_2048.csr -signkey server_2048.key -out server_2048.crt
[root@localhost nginx]# openssl x509 -req -days 365 -in server_2048.csr -signkey server_2048.key -out server_2048.crt
Signature ok
subject=C = CN, ST = Some-State, O = Internet Widgits Pty Ltd
Getting Private key

Enter the password set in 1. If password-free access is set for the file, you do not need to enter the password.

Running Nginx

  1. Start Nginx in either of the following ways:

    • Start the Nginx service. You need to add Nginx to the service list, and then start the service using a command.

      (1) Modify the /etc/init.d/nginx file.

      a. Delete the original nginx file.
      rm -rf /etc/init.d/nginx

      b. Create a new nginx file.
      vi /etc/init.d/nginx

      c. Add the following content to the file, and then save the file and exit.

	   #!/bin/bash
	   # chkconfig: 2345 10 90
	   # description: nginx
	   case "$1" in
	     'start')
	       /usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf
	       echo "$0_start";
	      ;;
	    'stop')
	     /usr/local/nginx/sbin/nginx -s quit
	     echo "$0_stop";
	     ;;
	   esac

(2) Modify the permission on the /etc/init.d/nginx file.

chmod 777 /etc/init.d/nginx

​ (3) Add Nginx to the chkconfig management list.
chkconfig --add /etc/init.d/nginx

​ (4) Enable Nginx to automatically start upon OS startup.
chkconfig nginx on

​ (5) Start Nginx.
service nginx start

  • Start Nginx by running a script.

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

  1. Check the Nginx process.
    ps -ef | grep nginx
[root@localhost nginx]# ps -ef | grep nginx
root        9463       1  0 18:22 ?        00:00:00 nginx: master process /usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf
root        9464    9463  0 18:22 ?        00:00:00 nginx: worker process
root        9466    1352  0 18:23 ttyAMA0  00:00:00 grep --color=auto nginx

NOTE: You can run any of the following commands to disable Nginx. Do not run the commands when the service is running.

  • Stop the Nginx service.

    service nginx stop

  • Stop Nginx by running a script.

    /usr/local/nginx/sbin/nginx -s quit

  • Stop the Nginx process.

```pkill nginx```
[root@localhost nginx]# pkill nginx
[root@localhost nginx]# ps -ef | grep nginx
root        9469    1352  0 18:27 ttyAMA0  00:00:00 grep --color=auto nginx

Verifying Nginx

  1. Check the Nginx monitoring port (10000 for the HTTP monitoring port and 20000 for the HTTPS monitoring port).
    netstat -anp | grep 10000netstat -anp | grep 20000netstat -anpt
[root@localhost nginx]# netstat -anp | grep 10000
tcp        0      0 0.0.0.0:10000           0.0.0.0:*               LISTEN      9535/nginx: master  
[root@localhost nginx]# netstat -anp | grep 20000
tcp        0      0 0.0.0.0:20000           0.0.0.0:*               LISTEN      9535/nginx: master  
[root@localhost nginx]# netstat -anpt
Active Internet connections (servers and established)
Proto Recv-Q Send-Q Local Address           Foreign Address         State       PID/Program name

  1. Query the directory where the HTML files of the Nginx are located.
    ll -h /usr/local/nginx/html/
[root@localhost nginx]# ll -h /usr/local/nginx/html/
total 8.0K
-rw-r--r--. 1 root root 537 Mar 20 16:46 50x.html
-rw-r--r--. 1 root root 612 Mar 20 16:46 index.html
  1. Verify the HTTPS function. Access the Nginx HTML page using cURL.
    curl -k https://127.0.0.1:20000/index.html
[root@localhost nginx]# curl -k  https://127.0.0.1:20000/index.html
