apache的使用

ref : http://www.apachetutor.org/admin/reverseproxies

Basic concept:

1) must install apr and apr-util (think about JVM) and source located on httpd/srclib, you can compile and install it.

2) on product environment, set linux run level 3

3) --enable-modules=most    (static compile to apache)

4)--enable-mods-shared=most  (dynamic shared object)

刪除源碼安裝的apache：

make clean

rm  -R /opt/httpd

安裝apache

1) download apr1.4.6, apr-util-1.5.1, mod_jk, pcre
http://www.apache.org/dist/apr/  (include apr and apr-util)
http://sourceforge.net/projects/pcre/files/pcre/  
http://www.apache.org/dist/tomcat/tomcat-connectors/jk/

2) install apr
#---------------------------------
tar zxvf apr-1.4.6.tar.gz
./configure --prefix=/opt/apr-1.4.6
./make && make install

3) install apr-util-1.4.1
#---------------------------------
tar zxvf apr-util-1.4.1.tar.gz
./configure --prefix=/opt/apr-util-1.4.1 --with-apr=/opt/apr-1.4.6
make && make install

4) install pcre
tar zxvf pcre-8.30.tar.gz
./configure --prefix=/opt/pcre
make && make install

5) copy apr related source to httpd-2.4.3/srclib/
#avoid Bundled APR requested but not found at ./srclib/ error doing the following copy
cp -rf apr-1.4.6 httpd-2.4.3/srclib/apr
cp -rf apr-util-1.5.1 httpd-2.4.3/srclib/apr-util

6) install apache-2.4.3
#---------------------------------
#./configure --prefix=/opt/apache2.4.3 \

--enable-file-cache \
