Nginx and apache limit ip connection number and bandwidth method

1, configure nginx.conf

code as follows http{ ............. limit_zone one $binary_remote_addr 10m; //I remember the default configuration, just commented out, if not added.............. server{ ............... .. location { ......... limit_conn one 20; //Connection limit limit_rate 500k; //Bandwidth limit ........ } ............ ..... } ............. }

[root@localhost nginx]# /etc/init.d/nginx reload //Reload

2, test limit ip connection number

Code is as follows [root@localhost nginx]# webbench -c 100 -t 2 http://127.0.0.1/index.php Webbench - Simple Web Benchmark 1.5 Copyright ( c) Radim Kolar 1997-2004, GPL Open Source Software.

[root@localhost nginx]# cat /var/log/nginx/access.log| Grep 503 | More //There are a lot of such data, it is best to add more or less 127.0.0.1 - - [25/Apr/2012:17:52:21 +0800] "GET /index.php HTTP/1.0" 503 213 "-" "WebBench 1.5" - 127.0.0.1 - - [25/Apr/2012:17:52:21 +0800] "GET /index.php HTTP/1.0" 503 213 "-" ; "WebBench 1.5" - 127.0.0.1 - - [25/Apr/2012:17:52:21 +0800] "GET /index.php HTTP/1.0" 503 213 "-" "WebBench 1.5" - 127.0.0.1 - - [25/Apr/2012:17:52:21 +0800] "GET /index.php HTTP/1.0" 503 213 "-" "WebBench 1.5" - 127.0.0.1 - - [25/Apr/2012:17:52:21 +0800] "GET /index.php HTTP/1.0" 503 213 "-" "WebBench 1.5" - 127.0.0.1 - - [25/Apr/2012:17:52:21 +0800] "GET /index.php HTTP/1.0" 503 213 "-" "WebBench 1.5" - 127.0.0.1 - - [25/Apr/2012:17:52:21 +0800] "GET /index.php HTTP/1.0" 503 213 "-" "WebBench 1.5" - 127.0.0.1 - - [25/Apr/2012: 17:52:21 +0800 ] "GET /index.php HTTP/1.0" 503 213 "-" "WebBench 1.5" -

Through the above test, it can be concluded that there is no problem in limiting the number of ip connections, but Limit bandwidth can't be seen, to be honest, this is not a good test, so it has not been tested

Use apache to limit IP concurrency and download traffic control

Install mod_limitipconn to limit the number of IP connections

1, download address: http://dominia.org/djao/limitipconn2.html

2, installation: [root@BlackGhost mod_limitipconn-0.22]# /usr/local/apache2/bin/apxs - c -i mod_limitipconn.c

3, the configuration is as follows vi httpd.conf

The code is as follows ExtendedStatus On LoadModule limitipconn_module modules/mod_limitipconn.so <IfModule mod_limitipconn.c> <Location /> #对根目录 MaxConnPerIP 6 #Maximum number of concurrent NoIPLimit im Age/* #No restrictions on images </Location> <Location /download> #downloadMaxConnPerIP 1 to the root directory #maximum number of concurrency 1 </Location> </IfModule>

Description: After unpacking mod_limitipconn-0.22.tar.gz, there is a README inside the file to be configured, and you can change it according to your own needs. If it doesn't, you can check it online, like apache. There are so many people, I think your problems have been encountered by others, and you can definitely find them. If you want to put the virtual host for maximum concurrency control, you can modify extra/httpd-vhost.conf to copy <IfModule mod_limitipconn.c> to <Virtualhost>

Install mod_bandwidth

mod_bandwidth can control the number of concurrent IPs, control the download traffic, and control the traffic of a directory.

1, download address: http://bwmod.sourceforge.net/

2, installation: [root@BlackGhost mod_bw]# /usr/local/apache2/bin/apxs -c -i mod_bw.c

3, configure the following vi httpd.conf plus LoadModule bw_module modules/mod_bw.so and then open vi httpd-vhosts.conf

code is as follows listen 10004 NameVirtualHost *:10004 <VirtualHost *:10004> DocumentRoot "/home/zhangy/www/test" ServerName *:10004 BandwidthModule On ForceBandWidthModule On Bandwidth all 1024000 MinBandwidth all 50000 LargeFileLimit * 500 50000 MaxConnection all 6 ErrorLog "/home/zhangy/apache/Www.test.com-error.log" CustomLog "/home/zhangy/apache/www.test.com-error.log" common </VirtualHost>

After decompressing the compressed file of bandwidth, inside There is a mod_bw.txt with detailed instructions and examples, the following are some of the parameter description:

1, BandWidth localhost 0 # not limited to localhost 2, BandWidth 192.168.1.5 102400 #对192.168 .1.5 rate limit is 100KB

3, BandWidth “u:^Mozilla(.*)” 10240 # speed limit 10KB with mozilla 4, BandWidth “u:wget” 102400 #If you download with wget Time limit 10KB

5, MinBandWidth all -1 # Guaranteed maximum speed of each client up to 10KB 6, LargeFileLimit .jpg 100 10240 #jpg file over 100KB, speed limit 10KB

7 ##The following 510 is quite good, if not set, apache will report an error, the root report is 404, the page is very ugly ErrorDocument 510 /exceed_speed.html BandWidthError 510

8,MaxConnection all 10 #All ip max The number of connections is 10 9, MaxConnection 192.168.1.5 5 #192.168.1.5 The maximum number of connections is 5
