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
# centos-base.repo [base] name=centos-4.7 - base - mirrors.ustc.edu.cn baseurl=http://vault.centos.org/4.7/os/$basearch/ gpgcheck=1 gpgkey=http://vault.centos.org/rpm-gpg-key-centos-4 #released updates [updates] name=centos-4.7 - updates - mirrors.ustc.edu.cn baseurl=http://vault.centos.org/4.7/updates/$basearch/ gpgcheck=1 gpgkey=http://vault.centos.org/rpm-gpg-key-centos-4 #additional packages that may be useful [extras] name=centos-4.7 - extras - mirrors.ustc.edu.cn baseurl=http://vault.centos.org/4.7/extras/$basearch/ gpgcheck=1 gpgkey=http://vault.centos.org/rpm-gpg-key-centos-4 #packages used/produced in the build but not released [addons] name=centos-4.7 - addons - mirrors.ustc.edu.cn baseurl=http://vault.centos.org/4.7/addons/$basearch/ gpgcheck=1 gpgkey=http://vault.centos.org/rpm-gpg-key-centos-4 #additional packages that extend functionality of existing packages [centosplus] name=centos-4.7 - plus - mirrors.ustc.edu.cn baseurl=http://vault.centos.org/4.7/centosplus/$basearch/ gpgcheck=1 enabled=0 gpgkey=http://vault.centos.org/rpm-gpg-key-centos-4 #contrib - packages by centos users [contrib] name=centos-4.7 - contrib - mirrors.ustc.edu.cn baseurl=http://vault.centos.org/4.7/contrib/$basearch/ gpgcheck=1 enabled=0 gpgkey=http://vault.centos.org/rpm-gpg-key-centos-4
yum makecache
yum安装完成，以后就可以用yum -y install <包名> 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。
