主机同时运行JSP和PHP

单位需要上一个php项目，但只有一个域名，服务器操作系统是redhat 4.7，已经布署了tomcat，重做或合并都不可能，但又必须共用一台主机，想到了用apache http server，用jk和tomcat连接，安装了php和mysql，前后花了不少时间，总算成功了，现记录如下： 
1、redhat4.7安装yum 
    redhat4.7默认没有安装yum，用yum安装软件确实比rpm方便，依赖性不用考虑，但有时也有找不到包的时候。
    redhat5默认已安装了yum,只需直接配置就可以了 
下载      yum wget http://www.parallels.com.cn/downloads/Prima/Tools/yum_forAS4.tar.gz 
解压      tar xzvf yum_forAS4.tar.gz 
进入目录  cd yum_forAS4  # 
安装      rpm -ivh *.rpm 
cd /etc/yum.repos.d/ 
vi CentOS-Base.repo

yum makecache 
yum安装完成，以后就可以用yum -y install b727d5ce35608c6cf98b783df26bbfcb 命令来安装软件，这还是非常方便的。 

2、安装apache，php，mysql 
yum -y install httpd httpd-devel php mysql mysql-server php-mysql httpd-manual mod_ssl mod_perl mod_auth_mysql php-mcrypt php-gd php-xml php-mbstring php-ldap php-pear php-xmlrpc mysql-connector-odbc mysql-devel libdbi-dbd-mysql 
用一个命令安装所有，php-mcrypt这个包没有装，在phpMyAdmin中会有警告，还是装上吧。 
在http://rpm.pbone.net/上查找以下包： 
libmcrypt-2.5.7-5.el4.i386.rpm 
php-common-5.3.10-2.el4.remi.i386.rpm 
php-mcrypt-4.3.9-1.el4.i386.rpm 
安装以上包。 
apache 配置文件安装在/etc/httpd/conf，WEB目录安装了/var/www/ 
启动： service httpd start 
停止： service httpd stop 
mysql 启动 service mysqld start 停止 service mysql stop 
设置mysql 帐号和密码（略） 

3、编译安装tomcat connectors 
wget tomcat-connectors-1.2.37-src.tar.gz 
cd tomcat-connectors-1.2.37-src 
cd native 
仔细阅读BUILDING.txt文件，文中提到需要apxs，这个程序是httpd-devel包中安装的 
查找apxs的位置，使用 
rpm -ql httpd-devel 
... 
/usr/sbin/apxs 
... 
其实apache http server 的可执行文件都放在/usr/sbin/目录下，该目录在PATH环境变量中的。 
./configure --with-apxs=/usr/sbin/apxs 
make 
在当前目录下生成了apache-1.3 和apache-2.0两个目录，我们用的是apache2.0 
cd apache-2.0 
cp mod_jk.so  /etc/httpd/modules/ 

4、配置jk. 
(1)创建workers.properties配置文件 
cd /etc/httpd/conf 
vi workers.properties 

# Define 1 real worker using ajp13
worker.list=worker1
# Set properties for worker1 (ajp13)
worker.worker1.type=ajp13
worker.worker1.host=localhost
worker.worker1.port=8009

(2)编辑httpd.conf 
在加载模块段落下加入以下行 

# Load mod_jk module
# Update this path to match your modules location
LoadModule    jk_module  modules/mod_jk.so
# Where to find workers.properties
# Update this path to match your conf directory location (put workers.properties next to httpd.conf)
JkWorkersFile /etc/httpd/conf/workers.properties
# Where to put jk shared memory
# Update this path to match your local state directory or logs directory
JkShmFile     /var/log/httpd/mod_jk.shm
# Where to put jk logs
# Update this path to match your logs directory location (put mod_jk.log next to access_log)
JkLogFile     /var/log/httpd/mod_jk.log
# Set the jk log level [debug/error/info]
JkLogLevel    info
# Select the timestamp log format
JkLogStampFormat "[%a %b %d %H:%M:%S %Y] "
# Send everything for context /examples to worker named worker1 (ajp13)
JkMount  /examples/* worker1

重启apache 

测试： 
用tomcat的端口可以访问，用apache的端口同样也可发访问同样的内容。 
如果用防火墙,要记得把lo的8009端口打开 
-A INPUT -i lo -p tcp -m tcp --dport 8009 -j ACCEPT 
好了，放在这里，下次配置就不会找不到了。
