Linux installation Nginx Server detailed introduction _nginx

Nginx relies on software libraries to ensure that the system installs GCC, SSL, pcre, and Gzip software prior to installation, and 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). The gzip module requires a zlib library (download: http://www.zlib.net/)
(2). Rewrite module requires pcre library (download: http://www.pcre.org/)
(3). SSL functionality requires OpenSSL library (download: http://www.openssl.org/)

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.gz
cd pcre-8.38
./configure make make
install

Install Nginx, and execute the following command

By default, a compiled installation of Nginx already contains most of the available modules, and you can use the "./configure--help" option to set the usage of each module, such as for unwanted http_ssi modules, through "--without-http_ssi_ Module parameter closes this module, and if the "Http_perl" module is required, you can install it through the "--with-http_perl_module" parameter. Perform the following actions to install.

TAR-ZXVF nginx-1.11.1.tar.gz
cd nginx-1.11.1
./configure--with-pcre=. /pcre-8.38--prefix=/usr/local/nginx make make
install

Detect if the installation was successful, execute the following command

[Root@redhat1 sbin]# Cd/usr/local/nginx/sbin
[Root@redhat1 sbin]#./nginx-t

The following information 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 ports

[Root@redhat1 sbin]# NETSTAT-NTLP

You can also enter in the browser: http://localhost to verify that the startup is successful.

Stop Nginx

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

Step 1: Query Nginx main process number:

Ps-ef | grep nginx

In the process list, look for the master process, which is numbered as the main process number.

Step 2: Send a signal

Calmly stop nginx:kill-quit the main process number
Quick Stop Nginx:kill-term The main process number
Force Stop nginx:pkill-9 Nginx

Reboot nginx: Smooth reboot

If you change the configuration, restart the Nginx, turn off Nginx before you open it? No, you can send a signal to the nginx, smooth reboot.
Smooth Restart command:

Kill-hup live 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 that the modified profile is correct so that the Nginx error affects the stable operation of the server after the reboot. Sentenced

The Nginx configuration is correctly ordered as follows:

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