apache 中如何添加mod_info.c這個文件

最近做實驗，發現在1.3.x , 2.2.x version中mod_status是defult安裝的，但是mod_info不是default安裝的。

如何安裝呢？

------------------apache 1.3.x----
[root@web232 standard]# /usr/local/apache/bin/apxs -cia mod_info.c
apxs:Error: Sorry, no DSO support for Apache available
apxs:Error: under your platform. Make sure the Apache
apxs:Error: module mod_so is compiled into your server
apxs:Error: binary `/usr/local/apache/bin/httpd'.

應該是沒有按照要求進行編譯

./configure --prefix=/usr/local/ --enable-module=so

如果這樣編譯就可以了

在2.2.x環境下
---apache2.2.x----
[root@web233 generators]# /usr/local/apache2/bin/apxs -cia mod_info.c
/usr/local/apache2/build/libtool --silent --mode=compile gcc -prefer-pic   -DLINUX=2 -D_REENTRANT -D_GNU_SOURCE -D_LARGEFILE64_SOURCE -g -O2 -pthread -I/usr/local/apache2/include  -I/usr/local/apache2/include   -I/usr/local/apache2/include   -c -o mod_info.lo mod_info.c && touch mod_info.slo

PATH="$PATH:/sbin" ldconfig -n /usr/local/apache2/modules
----------------------------------------------------------------------
Libraries have been installed in:
   /usr/local/apache2/modules
If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:
   - add LIBDIR to the `LD_LIBRARY_PATH' environment variable
     during execution
   - add LIBDIR to the `LD_RUN_PATH' environment variable
     during linking
   - use the `-Wl,--rpath -Wl,LIBDIR' linker flag
   - have your system administrator add LIBDIR to `/etc/ld.so.conf'
See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.
----------------------------------------------------------------------
chmod 755 /usr/local/apache2/modules/mod_info.so
[activating module `info' in /usr/local/apache2/conf/httpd.conf]
[root@web233 modules]# pwd
/usr/local/apache2/modules
[root@web233 modules]# ls
httpd.exp  mod_info.so
已经增加了
# Example:
# LoadModule foo_module modules/mod_foo.so
LoadModule info_module        modules/mod_info.so  ＃這個是自動添加上的

添加如下內容：
<Location /server-info>
    SetHandler server-info
    Order deny,allow
    Allow from all    #我這裡是測試環境所以也就這樣設了 production 環境注意一下
</Location>
http://172.16.1.233/server-info

看到信息了

注意httpd.conf中間ExtendedStatus 在2.2.x版本是沒有的

ExtendedStatus On

加上restart apache

就可以看到信息了

apache ab stress tool “apr_socket_recv: Connection reset by peer (104)” 的處理

使用apache 自帶的stresss tools ab, 如果併發設定的稍微大點就報錯了

類似：

[root@localhost bin]# ./ab -n 1000000 -c 2000 http://172.16.1.237/index.html

apr_socket_recv: Connection reset by peer (104)

Total of 80159 requests completed

開始懷疑是web server設置， os kernel parameter 設置的問題，後面發現不是， 而是ab 這個程序自身的問題，要打patch:

我用的是2.2.15 ，最新發佈的找到  srccode/support/ab.c

--修改代碼ab.c

   1367                 }

   1368                 return;

   1369             } else {

   1370                 //apr_err("apr_socket_recv", status); //原來的

   1371                 bad++;

   1372                 close_connection(c);

   1373                 return;

   1374             

   1375             }

   1376         }

   1377     }

make

使用這個新生成的ab做測試壓力可以達到20000

有時間再查，記錄一下

apache(2.2.15) +php(5.2.10) 實驗

這次測試加在php動態頁面的效果

apache pre-fork mode:

1, apache compiled

./configure --prefix=/usr/local/apache2 --enable-so --enable-rewrite --with-mpm=prefork

 

2 php compiled

./configure --prefix=/usr/local/php --with-config-file-path=/usr/local/php --with-mysql=/usr/local/webserver/mysql    --with-apxs2=/usr/local/apache2/bin/apxs

 

3. make 
make ZEND_EXTRA_LIBS='-liconv'

5. 編輯測試文件

[root@LB1 bin]# cd /usr/local/apache2/htdocs/

[root@LB1 htdocs]# ls

index.html

[root@LB1 htdocs]# vi index.php

[root@LB1 htdocs]# cat index.php

6, apache httpd.conf中添加：

 

設置web server環境

LoadModule php5_module        modules/libphp5.so
#指定php執行的副檔名
AddType application/x-httpd-php .php .phtml .inc .php3

btw:再進行work方式的時候使用類似上面的辦法報錯了“

[root@LB1 bin]# ./apachectl start

”解決，參見 上一篇文章

worker 方式：

1, apache complied

./configure --prefix=/usr/local/httpd2 --enable-so --enable-rewrite --with-mpm=worker

對比發現 ，從動態頁面來看，worker方式的優勢就顯現出來了，處理能力明顯被pre-fork方式強。

記錄一下，備忘

類似：error while loading shared libraries: libiconv.so.2 問題的處理

安裝apache2.2以後，發現啟動不了

報類似的錯誤：

 

error while loading shared libraries: libiconv.so.2: cannot open shared object file: No such file or directory

查找發現這個文件在/usr/local/lib下面

查看/etc/ld.so.conf 發現裏面沒有內容

將/usr/local/lib 添加在這個文件中

運行ldconfig

再次運行ok, 記錄一下備忘！

apache web server 實驗

項目需要, 做了一個 apache baseline的實驗, 發現再PC上, 我的測試機器是dell optiplex 755 , apache mpm worker mode 並沒有 pre-fork mode 的效率高,可能是multi-core的優勢沒有顯示出來吧,留一個記錄備查!

Fatal error: Call to undefined function mb_internal_encoding() in /dir/ administrator/components/com_k2/tables/k2category.php on line 46

試用k2 cck  extentsion 發現在增加categories的時候報 類似上述的錯誤, google,發現php編譯的時候少了一個參數 --enable-mbstring

我的腳本

./configure --prefix=/usr/local/php --with-apxs2=/usr/local/apache2/bin/apxs --with-mysql=/usr/local/mysql --with-gd=/usr/local/gd2 --with-freetype-dir=/usr/local/freetype --with-jpeg-dir=/usr/local/jpeg6 --with-zlib-dir=/usr/local/lib --with-png-dir=/usr/local/libpng2 --with-ttf --enable-soap --with-gd --enable-gd-native-ttf --enable-magic-quotes --enable-mbstring

重新編譯

漫長的等待后,再次測試,ok

Site Forms - jSeblod CCK :: The Content Type is missing or unpublished. 錯誤解決

 

在joolma上安裝了jSeblod CCK這個extension 還有 例子包 jSeblod_CCK_Simple_Demo_Pack_2009_08_31.zip 

看似一切順利, 但是在頁面上顯示上面的那條信息:

Site Forms - jSeblod CCK :: The Content Type is missing or unpublished.

google了一下居然沒有人遇到過, 無奈下在 jSeblod的forum上去找找看,果然找到了

在 extensions ->moudles manager –> 找到Site Forms - jSeblod CCK, 在右側的  Module Parameters, 中將 content type 和 jSeblod templete 設置一下,就ok了

參考:

http://www.jseblod.com/forum/41-bug-report/917-displaying-error-message-on-all-pages.html#917

Try to change parameters in Site Forms module, select an other Content Type and select the default submission template.

另外,joolma 在IE和firefox下的表現不同, ie下的表現似乎好一點, 有點震驚

joomla add extentsion jSeblod CCK error "Warning! - Failed to move file" 處理

領導要增加一個joomla extension jSeblod CCK, 一直添加報錯

Warning! - Failed to move file

檢查version沒有問題1.5.14

咋整呢, google發現有應該是權限的問題

1. 進入joomla administrator panel

2. –>help –> system info

3 有兩個目錄

Log Directory ($log_path) /var/www/vhosts/html/m-a-d/logs//
unWritable

Temp Directory ($tmp_path) /var/www/vhosts/html/m-a-d/tmp//
unWritable

因為是測試環境,不管那麼多了

[root@vm-linux64-server1 beta.m-a-d.asia]# mkdir -p /var/www/vhosts/html/m-a-d/logs/
[root@vm-linux64-server1 beta.m-a-d.asia]# mkdir -p /var/www/vhosts/html/m-a-d/tmp/
[root@vm-linux64-server1 beta.m-a-d.asia]# chmod -R 777 /var/www/vhosts/html/m-a-d/tmp/
[root@vm-linux64-server1 beta.m-a-d.asia]# chmod -R 777 /var/www/vhosts/html/m-a-d/logs/

再次安裝成功!

繼續研究

Guidelines for browsing design

聽一個講座關於wireless Mobile device 開發的,講到User Interface 設計時應該注意的技巧,覺得很有用,記錄一下:

- Use hyperlinks to replace other GUI components 

#尽量写hyperlink,不要用gui components ,我的理解是平臺獨立性

- Avoid horizontal Scrolling, use vertical  scrolling as possible 

#尽量避免横向的scroll bar

- Organize the content hierarchically 

- Arrange the hyperlink from top to bottom by importance

#根据重要性来组织内容

- Number the hyperlinks( for one-handed interaction) 

#控制hyperlink的密度

- Use link navigation for information searching.
