How to build a proxy server with squid in linux _ detailed enough

How to use squid to set up a proxy server in linux _ enough details on how to use squid to set up a proxy server in linux, which is around the world, but some details are unclear on the Internet, it has been a good job for a long time. In a computer linux system, how can we build a proxy server with squid in linux? _ enough detail to build a proxy server with squid in linux, however, some details are unclear on the internet. after a long time, they have done a good job. A computer linux system, on the network, so in another linux can access the Internet to build a proxy server, the steps are as follows: Download: squid-3.2.9.tar.bz2 uploaded to the server after decompression: Unzip: tar-vxjf squid-3.2.9.tar.bz2 decompress the package To generate the directory: squid-3.2.9 go To the directory To read the documentation INSTALL: xxxx> more INSTALL To build and install the Squid Cache, type: %. /configure -- prefix =/usr/local/squid % make all % make install To run a Cache, you will need to: 1. customize the squid. conf configuration file: % vi/usr/local/squid/etc/squid. con F 2. initalise the cache: %/usr/local/squid/sbin/squid-z 3. start the cache: %/usr/local/squid/sbin/squid If you want to use the WWW interface to the Cache Manager, copythe cachemgr. cgi program into your httpd server's cgi-bindirectory. installation steps :. /configure -- prefix =/usr/local/squidmake allsudo make install, I am a ubuntu system, so with sudo, you can check the configuration file: sudo vi/usr/ Local/squid/etc/squid. conf configuration item 1: # Squid normally listens to port 3128http_port 3128 Configuration Item 2: acl localnet src 192.168.0.0/16http_access allow localnet configuration item 3: # Uncomment and adjust the following to add a disk cache directory. cache_dir ufs/usr/local/squid/var/cache/squid 100 16 128cache_mem 32 MB (this item must be configured) or you will encounter an error: 16:16:55 kid1 | WARNING cache_mem is larger than total disk cache space! After the installation is complete, a user squid is created in the system. check the user squid in the group and find the user in the nobody Group: cat/etc/passwd | grep squidcat/etc/group | the directory where grep 65534 installs squid is/usr/local/squid, directly changed the user to squid: nobodysudo chown-Rf squid: nobody/usr/local/squid when creating a cache, the following Directory requires the nobody user permission, this is something I did not say clearly on the internet. I 've been tossing around for a long time: sudo chown-Rf nobody/usr/local/squid/var/cache/sudo chown-Rf nobody/usr/local/squid/var/logs/otherwise you will encounter: WARNING: cannot write log file:/usr/local/squ Id/var/logs/cache. logFATAL: Failed to make swap directory/usr/local/squid/var/cache/squid/00: (13) Permission denied initialize squid. the cache directory configured in conf is a bunch of directories: sudo/usr/local/squid/sbin/squid-z, and output the startup process sudo/usr/local/squid/sbin/squid-N-d1 to show ready to server reques, then the startup is successful. You can press ctrl + c to stop squid and start it later. I didn't configure DNS in the configuration file, but in/etc/resolv. configuration in conf: domain sitenameserver x. x. x. so the printed log is like this: 16:42:13 | Adding nameserver x. x. x. x from/etc/resolv. conf squid reads the dns configuration from this configuration file. Start the squid background and run sudo/usr/local/squid/sbin/squid-s to check whether the process exists: ps-ef | grep squid view squid running status/usr/local/squid/bin/squidclient-h 127.0.0.1-p 3128 mgr: the machine that cannot access the Internet in info is configured as follows: export http_proxy = http://192.168.199.235:3128/ You can write this sentence to your startup file, such as. profile or. bashrc, or/etc/profile. Cancel: unset http_proxy to test whether the Internet can be accessed: wget www.163.com can be down and the file will be down!
