在mod_pagespeed上安装CentOS (Apache模块)

Question

我有一个CentOS (5.7Final)系统，我已经安装了Apache2.2.3。

我按照关于: mod_pagespeed的说明安装了http://code.google.com/speed/page-speed/download.html，并在安装时获得了以下信息：

# rpm -U mod-pagespeed-*.rpm
warning: mod-pagespeed-beta_current_x86_64.rpm: Header V4 DSA signature: NOKEY, key ID 7fac5991
[  OK  ] atd: [  OK  ]

它似乎确实安装得很好：

# apachectl -t -D DUMP_MODULES
Loaded Modules:
...
 pagespeed_module (shared)

并且我在/etc/httpd/con.d/pagspeed.conf中做了以下修改

添加：

ModPagespeedEnableFilters collapse_whitespace,elide_attributes
ModPagespeedEnableFilters combine_css,rewrite_css,move_css_to_head,inline_css
ModPagespeedEnableFilters rewrite_javascript,inline_javascript
ModPagespeedEnableFilters rewrite_images,insert_img_dimensions
ModPagespeedEnableFilters extend_cache
ModPagespeedEnableFilters remove_quotes,remove_comments

ModPagespeedEnableFilters add_instrumentation

在mod_pagespeed_statistics中注释掉下列行

<Location /mod_pagespeed_statistics>
    **# Order allow,deny**
    # You may insert other "Allow from" lines to add hosts you want to
    # allow to look at generated statistics.  Another possibility is
    # to comment out the "Order" and "Allow" options from the config
    # file, to allow any client that can reach your server to examine
    # statistics.  This might be appropriate in an experimental setup or
    # if the Apache server is protected by a reverse proxy that will
    # filter URLs in some fashion.
    **# Allow from localhost**
    **# Allow from 127.0.0.1**
    SetHandler mod_pagespeed_statistics
</Location>

作为一个单独的注意，我试图运行指定的系统测试谷歌的网站，但它提供了以下错误。我不喜欢更新服务器上的wget，因为我确信没有必要让实际模块正常工作。

./system_test.sh www.domain.com
You have the wrong version of wget. 1.12 is required.

我在一个mod_pagespeed系统上安装CentOS时遇到了一个问题，它只是在安装后拒绝工作。

事实证明，特定文件夹存在权限/所有权访问问题(S)。

在/var/www/中存在：

drwxr-xr-x  4 root      root   4096 Dec  8 12:02 mod_pagespeed
drwxr-xr-x  2 root      root   4096 Dec  8 12:03 mod_pagespeedcache

我将权限更改为：

drwxr-xr-x  4 apache    apache 4096 Dec  8 12:02 mod_pagespeed
drwxr-xr-x  4 apache    apache 4096 Dec 10 13:10 mod_pagespeedcache

日志显示：

...
[Sat Dec 10 13:08:43 2011] [error] [mod_pagespeed 0.10.19.4-1209 @30739] /var/www/mod_pagespeedcache/XAM3DOzfwmGm-DkPVUC7.outputlock:0: creating dir (code=13 Permission denied)
...

在那之后工作得很好。
