This article mainly introduces the relevant knowledge of "Linux installation nginx server instance code analysis". The editor shows you the operation process through the actual case. The operation method is simple, fast and practical. I hope this "Linux installation nginx server instance code analysis" article can help you solve the problem.

Nginx relies on some software libraries. Before installing, make sure that the system has software such as gcc, ssl, pcre, and gzip installed. You can use the rpm-Q command to see if the software is installed.

[root@redhat1] # rpm-Q gcc

Gcc-4.1.2-44.el5

The dependent library information is as follows:

(1)。 Gzip module requires zlib library

(2)。 Rewrite module requires pcre library

(3)。 Openssl library is required for ssl function

If you install pcre, download pcre to the destination directory. The version selected here is pcre-8.38. After downloading, perform the following actions

Tar-zxvf pcre-8.38.tar.gzcd pcre-8.38./configuremakemake install

To install nginx, execute the following command

By default, the compiled and installed nginx already contains most of the available modules, and you can use the ". / configure-- help" option to set the usage of each module. For example, for unwanted http_ssi modules, you can close this module with the "--without-http_ssi_module" parameter; if you need a "http_perl" module, you can install this module with the "--with-http_perl_module" parameter. Do the following to install.

Tar-zxvf nginx-1.11.1.tar.gzcd nginx-1.11.1./configure-with-pcre=../pcre-8.38-prefix=/usr/local/nginxmakemake install

To check whether the installation is successful, execute the command as follows

[root@redhat1 sbin] # cd / usr/local/nginx/sbin

[root@redhat1 sbin] #. / nginx-t

The following message appears to prove that the installation was successful

Nginx: the configuration file / usr/local/nginx/conf/nginx.conf syntax is ok

Nginx: configuration file / usr/local/nginx/conf/nginx.conf test is successful

Start nginx

[root@redhat1 sbin] #. / nginx

View Port

[root@redhat1 sbin] # netstat-ntlp

The results are as follows:

Stop nginx

The stop operation is done by sending a signal to the nginx process

Step 1: query the nginx main process number:

Ps-ef | grep nginx

Look for the master process in the process list, and its number is the main process number.

Step 2: send a signal

Stop the nginx:kill-quit main process number calmly

Quick stop nginx:kill-term main process number

Forcibly stop nginx:pkill-9 nginx

Restart nginx: smooth restart

If you change the configuration, you have to restart nginx. Do you want to close nginx and then turn it on? No, you can send a signal to nginx and restart smoothly.

Smooth restart command:

Kill-hup resides in the title or process number file path or / usr/local/nginx/sbin/nginx-s reload

Note that after modifying the configuration file, it is best to check whether the modified configuration file is correct, so as to avoid errors in nginx that affect the stable operation of the server after restart. Judge

The correct command to disconnect nginx configuration is as follows:

Nginx-t-c / usr/local/nginx/conf/nginx.conf or / usr/local/nginx/sbin/nginx-t
