How to install Nginx in Linux

Prepare to install tools

\1. Download Nginx from the Nginx official website. The version used here is: 1.13.6.

\2. Upload the downloaded Nginx to Linux. Here we take the /opt/nginx directory as an example. Run "tar -zxvf nginx-1.13.6.tar.gz" to decompress.

\3. Switch to the /opt/nginx/nginx-1.13.6 directory and run ./configure for initial configuration. If the following prompt appears, it means that PCRE is not installed on the machine, and Nginx needs to rely on PCRE. PCRE needs to be installed manually. You can search and view it in the forum.

Hands-on installation of pcre

PCRE (Perl Compatible Regular Expressions) is a lightweight Perl function library, including a perl-compatible regular expression library. It is much smaller than regular expression libraries like Boost. PCRE is very easy to use and very powerful. Its performance exceeds the POSIX regular expression library and some classic regular expression libraries.

\1. First go to https://sourceforge.net/projects/pcre/files/pcre/ to download pcre. The version downloaded here is 8.40.

\2. Change pcre- Upload 8.40.tar.gz to the /opt/pcre directory, run "tar -zxvf pcre-8.40.tar.gz", extract the pcre-8.40 directory, and then run chmod –R 777 pcre-8.40 to grant the current folder Full read and write permissions.

\3. Enter the /pcre-8.40 directory, run ./configure for initial configuration, and print a bunch of information. If the following prompt appears, it is because the C compiler is missing.

Solution: Use the yum –y install gcc-c command to install the C compiler.

Run ./configure after the C compiler is installed successfully.

\4. Execute make operation to compile.

\5. Finally execute the make install command, and the pcre installation is completed.

Continue back to the /opt/nginx/nginx-1.13.6 directory, run ./configure to initialize nginx configuration, and finally print out the following information to prove success. The address pointed by the red arrow is when starting nginx path of.

(Note: When running ./configure for nginx initialization configuration, if you want to add the ssl module, you can use the following command:

./configure &ndash ;-prefix=/usr/local/nginx –-with-http_ssl_module

If openssl has not been installed when executing the above command, you will be prompted:

./configure: error: SSL modules require the OpenSSL library.

At this time, execute yum –y install openssl openssl-devel. After installing openssl, you can proceed with the above operations smoothly)

\4. Run make install to install

\5. Go to the /usr/local/nginx/sbin directory, run ./nginx, and start nginx.

\6. To test whether the installation and startup are successful, enter the server IP: port (default 80) in the browser. If the following figure appears, the installation and startup have been successful.

Run test nginx

nginx common commands:

View nginx process: ps –ef|grep nginx

Start nginx, go to the /usr/local/nginx/sbin directory and execute: ./nginx

Close nginx: Go to the /usr/local/nginx/sbin directory, Execute: ./nginx -s quit

nginx configuration file is in /usr/local/nginx/conf/nginx.conf. After the configuration file nginx.conf is modified, nginx must be restarted to make the configuration take effect. , then you can use ./nginx -s reload to make the modified configuration take effect, without having to stop and then start
