ubuntu 下的squid安裝日誌

ubuntu 9.0.4

 

1） 安裝

 

wget http://www.squid-cache.org/Versions/v3/3.0/squid-3.0.STABLE20.tar.gz tar xzvf squid-3.0.STABLE20.tar.gz cd squid-3.0.STABLE20/ ./configure --prefix=/path/to/squid

 

遇到問題
checking for C++ compiler default output file name...
configure: error: C++ compiler cannot create executables
See `config.log' for more details.
configure: error: ./configure failed for lib/libTrie

 

解決：
sudo apt-get install g++

重新編譯 ok

make && 　make install

2)配置

在${squid_home}/etc/squid.cof中加入

#配置 squid 爲加速模式 http_port 80 accel vhost vport #配置反向代理的服務器 ，originserver 參數指明是源服務器， cache_peer 127.0.0.1 parent 8080 0 no-query originserver   

 

驗證配置

${squid_home}/sbin/squid – k parse

3）生成緩存目錄

${squid_home}/sbin/squid -z  

默認會在${squid_home}/var/cache下生成一堆目錄

4）啓動

sudo ${squid_home}/sbin/squid

發現問題：
squid進程起來了，但很快消失，並有錯誤日誌

FATAL: Cannot open '/home/pwlazy/dev/squid/var/logs/access.log' for writing.
    The parent directory must be writeable by the
    user 'nobody', which is the cache_effective_user
    set in squid.conf.

 

解決：
sudo chown -R nobody /home/pwlazy/dev/squid/var/logs/access.log
再次啓動，發現問題：
FATAL: Cannot open '/home/pwlazy/dev/squid/var/logs/store.log' for writing.
    The parent directory must be writeable by the
    user 'nobody', which is the cache_effective_user
    set in squid.conf.
解決：
sudo chown -R nobody /home/pwlazy/dev/squid/var/logs/store.log
再次仍然問題
2009/11/14 02:31:38| /home/pwlazy/dev/squid/var/cache/00: (13) Permission denied
FATAL:     Failed to verify one of the swap directories, Check cache.log
    for details.  Run 'squid -z' to create swap directories
    if needed, or if running Squid for the first time.

解決
sudo chown -R nobody /home/pwlazy/dev/squid/var/cache

上面的問題非常類似，總結一下：
squid起來之後會有一個父進程,和1個或者多個工作進程，這些工作進程會讀寫access.log和store.log以及cache目錄
而父進程會讀寫cache.log

 

5）從頁面訪問

http://127.0.0.1

發現問題：
403

 

解決：
於是修改配置文件，
將http_access deny all改爲
http_access allow all
再次訪問ok

 

6)清除緩存

bin/squidclient -m PURGE -p 80 "http://127.0.01/"

發現問題

403

 

解決
acl AdminBoxes src 127.0.0.1 acl Purge method PURGE http_access allow AdminBoxes Purge http_access deny Purge
