Linux – Perl 使用 Proxy

當 Perl 安裝模組透過 cpan 或是 cpanm 時須透過 公司 Proxy 時,這時候可以在 perl 的 shell 來進行設定.

設定 Proxy

進入 perl 的 shell 來進行設定,透過 o conf http_proxy 先觀察有無設定過 .

[root@localhost ~]# perl -MCPAN -e shell
Terminal does not support AddHistory.

cpan shell -- CPAN exploration and modules installation (v1.9600)
Enter 'h' for help.

cpan[1]> o conf http_proxy
    http_proxy         []
Type 'o conf' to view all configuration items

透過 o conf init /proxy/ 來設定,可以依據需求來設定是 FTP 或是 HTTP Proxy.

cpan[2]> o conf init /proxy/

If you're accessing the net via proxies, you can specify them in the
CPAN configuration or via environment variables. The variable in
the $CPAN::Config takes precedence.

 <ftp_proxy>
Your ftp_proxy? [] 

 <http_proxy>
Your http_proxy? [] a.b.c.d:port

 <no_proxy>
Your no_proxy? [] 

If your proxy is an authenticating proxy, you can store your username
permanently. If you do not want that, just press ENTER. You will then
be asked for your username in every future session.

Your proxy user id? [] ben10

Your password for the authenticating proxy can also be stored
permanently on disk. If this violates your security policy, just press
ENTER. You will then be asked for the password in every future
session.

Your proxy password?  

Please remember to call 'o conf commit' to make the config permanent!

最後還需要寫回至設定檔.

cpan[3]> o conf commit
commit: wrote '/root/.cpan/CPAN/MyConfig.pm'

確認一下 http_proxy 設定.

cpan[4]> o conf http_proxy  
    http_proxy         [a.b.c.d:port]
Type 'o conf' to view all configuration items

ctrl + D 可跳出 perl 的 shell.

cpan[5]> Terminal does not support GetHistory.
Lockfile removed.

取消設定 Proxy

要取消設定 Proxy,一樣需進入 perl 的 shell 來進行設定,透過 o conf http_proxy 先觀察有無設定過 .

[root@localhost ~]# perl -MCPAN -e shell
Terminal does not support AddHistory.

cpan shell -- CPAN exploration and modules installation (v1.9600)
Enter 'h' for help.

cpan[1]> o conf http_proxy 
    http_proxy         [a.b.c.d:port]
Type 'o conf' to view all configuration items

取消設定 Proxy.

cpan[2]> o conf http_proxy ''
    http_proxy         []
Please use 'o conf commit' to make the config permanent!

最後還需要寫回至設定檔.

cpan[3]> o conf commit
commit: wrote '/root/.cpan/CPAN/MyConfig.pm'

確認一下 http_proxy 設定,的確已取消.

cpan[3]> o conf http_proxy
    http_proxy         []
Type 'o conf' to view all configuration items

ctrl + D 可跳出 perl 的 shell.

cpan[4]> Terminal does not support GetHistory.
Warning: Configuration not saved.
Lockfile removed.
