Imagine,you’ve got a task now to verify a bulk of domains the speed of response and  whether they are active or not.Here a bulk of,means,for example,1,000.On getting this task,what will you do next?Type in every ip in the command line in Microsoft’s cmd and waits for the result?1,000,you must consider it.You may imagine,how tired after you’ve pinged the full 1,000 of the urls.

Here is my implement of the task.Firstly,put the urls in domain.txt,one url per line.Then run the script:sh if.sh.Lastly,waits for the result in ip.txt.During the execution time,you may go out and breath fresh air or have a cup of tea,not type in the Microsoft cmd any more! Read more…

Sometimes,we want to see the compiled parameters of nginx，apache，mysql，php etc. after the compilation.Consider the following method.
nginx compilation parameters：
#/usr/local/nginx/sbin/nginx -V
nginx version: nginx/0.6.32 built by gcc 4.1.2 20071124 (Red Hat 4.1.2-42) configure arguments: –user=www –group=www –prefix=/usr/local/nginx/ –with-http_stub_status_module –with-openssl=/usr/local/openssl

apache compilation parameters：
# cat /usr/local/apache2/build/config.nice
#! /bin/sh # # Created by configure “./configure” \ “–prefix=/usr/local/apache2″ \ “–with-included-apr” \ “–enable-so” \ “–enable-deflate=shared” \ “–enable-expires=shared” \ “–enable-rewrite=shared” \ “–enable-static-support” \ “–disable-userdir” \ “$@”

php compilation parameters：
# /usr/local/php/bin/php -i |grep configure
Configure Command => ‘./configure’ ‘–prefix=/usr/local/php’ ‘–with-apxs2=/usr/local/apache2/bin/apxs’ ‘–with-config-file-path=/usr/local/php/etc’ ‘–with-mysql=/usr/local/mysql’ ‘–with-libxml-dir=/usr/local/libxml2/bin’ ‘–with-gd=/usr/local/gd2′ ‘–with-jpeg-dir’ ‘–with-png-dir’ ‘–with-bz2′ ‘–with-xmlrpc’ ‘–with-freetype-dir’ ‘–with-zlib-dir’

mysql compilation parameters：
# cat “/usr/local/mysql/bin/mysqlbug”|grep configure
# This is set by configure CONFIGURE_LINE=”./configure ‘–prefix=/usr/local/mysql’ ‘–localstatedir=/var/lib/mysql’ ‘–with-comment=Source’ ‘–with-server-suffix=-H863′ ‘–with-mysqld-user=mysql’ ‘–without-debug’ ‘–with-big-tables’ ‘–with-charset=gbk’ ‘–with-collation=gbk_chinese_ci’ ‘–with-extra-charsets=all’ ‘–with-pthread’ ‘–enable-static’ ‘–enable-thread-safe-client’ ‘–with-client-ldflags=-all-static’ ‘–with-mysqld-ldflags=-all-static’ ‘–enable-assembler’ ‘–without-isam’ ‘–without-innodb’ ‘–without-ndb-debug’”

vhcs2_debian.sh,chmod +x ./vhcs2_debian.sh,./vhcs2_debian.sh.In the process,you must type in the main ip of your server.And,set the parameters during the installation(for example,mysql password etc.)

To put an elephant into a fridge-three steps(which I think you already knew it):

Firstly(open the fridge):In nginx,add a line in /usr/local/nginx/conf/proxy.conf:
proxy_set_header        X-Real-IP       $remote_addr;
#Note:Add this just in proxy.conf,repetitive addition in nginx.conf location and server place will result your backend server log repetitive times.

Secondly(put the elephant in):In backend apache server,add the following lines in place VirtualHost or Server: Read more…

This script by me accomplish the auto installation of nginx reverse server under centos.Please modify upstream and server_name scope in nginx.conf after the installation.And you do not need to modify proxy.conf(Of course,you can.For example,to get the real user ip in backend apache server).

This script by me accomplish the auto installation of nginx reverse server under debian.Please modify upstream and server_name scope in nginx.conf after the installation.And you do not need to modify proxy.conf(Of course,you can.For example,to <a href=”http://www.doxer.org/learn-linux/nginx-real-userip/” target=”_blank”></a>

Ok.That’s all.Now bootstrap from start the nginx server:/usr/local/nginx/sbin/nginx.Change the listening port on apache to 81(NameVirtualHost *:81 and <VirtualHost *:81>).Visit your site and now take a look at the response header sent by your nginx reverse server.You will find Server:nginx/0.7.30 in your firebug’s Net label.Enjoy the high concurrent processing ability of nginx now!
