centOS7 install nginx and nginx configuration

Install required plugins

1. Install gcc

gcc is a compiler under linux. I will not explain it here. Interested partners can check the relevant information. It can compile languages ​​such as C, C++, Ada, Object C and Java.

Command: check gcc version 

gcc -v

 

Generally, Alibaba Cloud's centOS7 has it. If it is not installed, it will prompt that the command cannot be found.

Installation command:

yum -y install gcc

 

2, pcre, pcre-devel installation

pcre is a perl library, including a perl-compatible regular expression library. The http module of nginx uses pcre to parse regular expressions, so the pcre library needs to be installed.

Installation command:

yum install -y pcre pcre-devel

 

3. zlib installation

The zlib library provides a variety of compression and decompression methods. nginx uses zlib to gzip the content of the http package, so it needs to be installed

Installation command:

yum install -y zlib zlib-devel

 

4. Install openssl

OpenSSL is the cornerstone of web security communication. Without OpenSSL, it can be said that our information is streaking. . . . . .

Installation command:

yum install -y openssl openssl-devel

 

install nginx

1. Download the nginx installation package

wget http://nginx.org/download/nginx-1.9.9.tar.gz  

 

2. Unzip the compressed package to usr/local/java

tar -zxvf  nginx-1.9.9.tar.gz

 

3. Switch to cd /usr/local/java/nginx-1.9.9/ below

Execute three commands:

./configure

make

make install

 

4. Switch to the /usr/local/nginx installation directory

5. Configure the nginx configuration file nginx.conf file, mainly the port

It can be configured according to the port usage of your own server

ESC key, wq! force save and exit

6. Start the nginx service

Change the directory to /usr/local/nginx/sbin

Start the nginx command:

./nginx

 

7. Check whether the nginx service is started successfully

ps -ef | grep nginx

 

8. Access your server IP

show

The installation and configuration are all OK.
