Linux system installation and configuration of Nginx

1.1 Version

Note: Versions prior to nginx-1.14.1 have multiple security issues. nginx-1.15.6 is recommended, and users of historical versions are advised to upgrade.

1.2 Environmental Preparation

2.1 Unzip the installation package

Place the installation package in a directory, e.g. /usr/nginx, and unzip.

mkdir /usr/nginx # Create installation directory
cd /usr/nginx # Go to Directory
tar zxvf nginx-1.15.6.tar.gz # unzip nginx-1.15.6
tar zxvf pcre-8.42.tar.gz # unzip pcre
tar zxvf zlib-1.2.11.tar.gz # unzip zlib
tar zxvf openssl-1.1.1a.tar.gz # unzip openssl
unzip ngx_healthcheck_module-master.zip # unzip ngx_healthcheck_module-master

2.2 Install Nginx

Note: The path 「/usr/nginx」   in the third line of the command below needs to be the same as the installation directory in section 2.1; since the third line is too long, we suggest users copy the following command to the local area and confirm the path before executing it in order.

cd /usr/nginx/nginx-1.15.6 # Go to the decompression directory
patch -p1 < /usr/nginx/ngx_healthcheck_module-master/nginx_healthcheck_for_nginx_1.14+.patch # Apply health check patch
./configure --prefix=/usr/nginx --with-pcre=/usr/nginx/pcre-8.42 --with-zlib=/usr/nginx/zlib-1.2.11 --with-openssl=/usr/nginx/openssl-1.1.1a --with-stream --add-module=/usr/nginx/ngx_healthcheck_module-master # 指定安装路径
make && make install # The two commands connected with && will continue to execute the make install command only if make is error-free

To use Nginx with web containers for load balancing, you must also configure Nginx, and both generic and custom configurations are provided below.

Note: The Nginx configuration in this chapter only supports purely direct-connected JARs.

3.1 General Configuration

1）General Configuration ：nginx-Genral.conf

Modify the IPs and ports of the nodes boxed in red in the file, as shown below.

2) Rename it to nginx.conf and replace the original /usr/nginx/conf/nginx.conf

3.2 Custom Configuration

vi /usr/nginx/conf/nginx.conf # Edit Configuration File nginx.conf

Refer to the Nginx configuration manual for a description of the Nginx configuration parameters, and configure them yourself (modify Nginx ports, configure extranet mapping, configure https, etc.).

4.1 Operation and maintenance commands

cd /usr/nginx/sbin # Go to the sbin directory
./nginx # Starting nginx
./nginx -s stop # Stop nginx
./nginx -s reload # Hot loading nginx, which can be interpreted as a reboot, but is not perceived by the user

For more information on operations and maintenance, see: Cluster Operations and Maintenance Manual - Linux Edition

4.2 Test for success

Enter ip:load balancing port number/status in the browser to view the health page, you can see the node health status, if the status is up, it means normal, as shown in the following figure.
