A deep understanding of nginx complete installation

1. Install nginx 1.1 in advance

Install nginx library package dependencies in centos. The installation command is as follows:

sudo yum groupinstall "DevelopmentTools"sudo yum install pcre pcre-develsudo yum install zlib zlib-develyum install perl-ExtUtils-Embedsudo yum install openssl openssl-devel

1.2 Installation

The most important feature is the modularization Based on HTTP and HTTPS content. The configuration parameter can be as follows:

./configure  --prefix=/usr/local/nginx-1.5.13--user=app --group=app --with-http_ssl_module --with-http_realip_module

Install all necessary modules:

./configure --user=app --group=app--with-http_ssl_module --with-http_realip_module --with-http_addition_module--with-http_xslt_module --with-http_image_filter_module--with-http_geoip_module --withhttp_sub_module --with-http_dav_module--with-http_flv_module --withhttp_mp4_module --with-http_gzip_static_module--with-http_random_index_module --with-http_secure_link_module--with-http_stub_status_module --with-http_perl_module--with-http_degradation_module

Use the root user or the administrator user to execute this command.

sudo make & sudo make install

….cp conf/scgi_params            '/usr/local/nginx-1.5.13/conf/scgi_params.default'test -f '/usr/local/nginx-1.5.13/conf/nginx.conf'               || cp conf/nginx.conf'/usr/local/nginx-1.5.13/conf/nginx.conf'cp conf/nginx.conf '/usr/local/nginx-1.5.13/conf/nginx.conf.default'test -d '/usr/local/nginx-1.5.13/logs'          || mkdir -p'/usr/local/nginx-1.5.13/logs'test -d '/usr/local/nginx-1.5.13/logs' ||               mkdir -p'/usr/local/nginx-1.5.13/logs'test -d '/usr/local/nginx-1.5.13/html'          || cp -R html'/usr/local/nginx-1.5.13'test -d '/usr/local/nginx-1.5.13/logs' ||               mkdir -p'/usr/local/nginx-1.5.13/logs'make[1]: Leaving directory `/home/app/Downloads/nginx-1.5.13'

1.3 Test

To test whether the nginx configuration is correct, run the following command:

Start nginx

#sudo  /usr/local/nginx-1.5.13/sbin/nginx

View the http: // localhost page. The result is as follows:

Welcome to nginx!

2. Use commands

After nginx is successfully installed, you need to know the basic commands.

nginx –s stop Stops the daemon immediately (using the TERM signal)nginx –s quit Stops the daemon gracefully (using the QUIT signal)nginx –s reopen Reopens the log filesnginx –s reload Reloads the configuration

Stop the nginx process and enter the following command:

Killall nginx

Test whether the configuration is successful:

[[email protected] sbin]$ sudo/usr/local/nginx/sbin/nginx  -t[sudo] password for app:nginx: the configuration file/usr/local/nginx/conf/nginx.conf syntax is oknginx: configuration file/usr/local/nginx/conf/nginx.conf test is successful

For more information about nginx commands, enter:

[[email protected]]$ ./nginx -hnginxversion: nginx/1.5.13Usage:nginx [-?hvVtq] [-s signal] [-c filename] [-p prefix] [-g directives] Options:  -?,-h        : this help  -v           : show version and exit  -V           : show version and configure options then exit  -t           : test configuration and exit  -q           : suppress non-error messages during configuration testing  -ssignal     : send signal to a masterprocess: stop, quit, reopen, reload  -p prefix    : set prefix path (default: /usr/local/nginx/)  -c filename  : set configuration file (default: conf/nginx.conf)  -g directives : set global directives out ofconfiguration file

The following table shows different running levels and their meanings.

After learning about the running level of the system process, we can add nginx to the system service. Create an nginx script in the/etc/init. d directory. For example, the nginx script can be configured as follows:

Bytes ---------------------------------------------------------------------------------------------------

Modify the execution permission.

#sudo chmod +x /etc/init.d/nginx

Restart nginx:

sudo /usr/init.d/nginx reload

Add nginx to the Automatic startup file list:

sudo chkconfig –add nginx

Check the running level of nginx:

[[email protected]~]$ sudo chkconfig --list nginxnginx           0:off   1:off  2:off   3:off   4:off  5:off   6:off
