Compile the tutorial on how to install nginx and configure the thumbnail plug in under CentOS

I'm sure you all know that installing nginx with yum is very convenient, but some plug-ins do not install by default, such as http_image_filter_module, so we need to compile and install nginx. Let's take a look at the details.

Install dependencies

yum install -y pcre-devel libmxl2-devel libxslt-devel gd-devel

Install nginx

wget http://nginx.org/download/nginx-1.9.1.tar.gz
tar -xzvf nginx-1.9.1.tar.gz
cd nginx-1.9.1
./configure\
 --user=nginx\
 --group=nginx\
 --with-http_ssl_module\
 --with-http_spdy_module\
 --with-http_realip_module\
 --with-http_addition_module\
 --with-http_xslt_module\
 --with-http_image_filter_module\
 --with-http_sub_module\
 --with-http_auth_request_module\
 --with-http_stub_status_module\
 --with-http_gzip_static_module 
make 
make install

Once the installation is complete, you can use the following command to view the modules installed by nginx

[root@linux001 ~]# /usr/local/nginx/sbin/nginx -V
nginx version: nginx/1.9.1
built by gcc 4.4.7 20120313 (Red Hat 4.4.7-11) (GCC) 
built with OpenSSL 1.0.1e-fips 11 Feb 2013
TLS SNI support enabled
configure arguments: --user=nginx --group=nginx --with-http_ssl_module --with-http_spdy_module --with-http_realip_module --with-http_addition_module --with-http_xslt_module --with-http_image_filter_module --with-http_sub_module --with-http_auth_request_module --with-http_stub_status_module --with-http_gzip_static_module --with-http_image_filter_module

Add startup script

New file/etc/init d/nginx, content is as follows:

#!/bin/sh
#
# nginx - this script starts and stops the nginx daemon
#
# chkconfig: - 85 15 
# description: Nginx is an HTTP(S) server, HTTP(S) reverse \
#    proxy and IMAP/POP3 proxy server

   if [ ! -d "$value" ]; then
    # echo "creating" $value
    mkdir -p $value && chown -R $user $value

Add/etc/init d/nginx, need to increase the execute permissions, and then you can use the script to start and stop nginx.

chmod a+x /etc/init.d/nginx 
/etc/init.d/nginx start
/etc/init.d/nginx stop
/etc/init.d/nginx restart
/etc/init.d/nginx reload

Or start and stop nginx with a service.

service nginx start
service nginx stop
service nginx restart
service nginx reload

Set auto-start

chkconfig --add nginx
chkconfig --level 345 on
