Apache实现不同域名访问
环境:CentOS6.2_X64
软件:httpd-2.2.9.tar.gz mysql apache-tomcat-6.0.37.tar.gz
需求：通过公网访问不同域名跳转mail_server和 gm_server(java语言)
邮件服务器 192.168.100.95:80端口
GM服务器 192.168.100.95:8080端口
公网IP 49.5.2.211
1． 安装apache软件
[root@mail~]# tar -zxvf /data/soft/httpd-2.2.9.tar.gz -C /usr/local/src/
[root@mail~]# cd /usr/local/src/httpd-2.2.9/
[[email protected]]# yum -y install make gcc gcc-c++ #如已安装可忽略
[[email protected]]# ./configure --prefix=/usr/local/apache2 --enable-so--enable-rewrite
[[email protected]]# make ; make install
[[email protected]]# /usr/local/apache2/bin/apachectl start
httpd: Could not reliably determine theserver's fully qualified domain name, using mail.utongame.com for ServerName
#修改配置文件可解决以上报错
[[email protected]]# vi /usr/local/apache2/conf/httpd.conf
#ServerName www.example.com:80
ServerName mail.utongame.com:80
[[email protected]]# /usr/local/apache2/bin/apachectl restart
[[email protected]]# echo "/usr/local/apache2/bin/apachectl start" >>/etc/rc.local
[[email protected]]# netstat -anptl | grep :80
tcp 0 0 :::80 :::* LISTEN 21473/httpd
2． 安装mysql软件
[[email protected]]# useradd -M -s /sbin/nologin mysql
[[email protected]]# tar -zxvf /data/soft/mysql-5.0.95.tar.gz -C /usr/local/src/
[[email protected]]# cd /usr/local/src/mysql-5.0.95/
[[email protected]]# ./configure --prefix=/usr/local/mysql ;make ;make install
checking for termcap functions library...configure: error: No curses/termcap library found
#出现以上报错，安装软件包ncurses-devel即可解决
[[email protected]]# yum -y install ncurses-devel
[[email protected]]# cp support-files/my-medium.cnf /etc/my.cnf
[[email protected]]# /usr/local/mysql/bin/mysql_install_db --user=mysql #初始化
[[email protected]]# chown -R root:mysql /usr/local/mysql
[[email protected]]# chown -R mysql /usr/local/mysql/var
#添加库文件路径,否则编译安装postfix会提示找不到lmysqlclient
[[email protected]]# vim/etc/ld.so.conf.d/mysql.conf
/usr/local/mysql/lib/mysql/ #添加此行
[root@mail mysql-5.0.95]# ldconfig -v |grep mysql
/usr/local/mysql/lib/mysql:
libmysqlclient.so.15-> libmysqlclient.so.15.0.0
/usr/lib64/mysql:
libmysqlclient.so.16-> libmysqlclient.so.16.0.0
libmysqlclient_r.so.16-> libmysqlclient_r.so.16.0.0
[[email protected]]# cp support-files/mysql.server /etc/init.d/mysqld
[[email protected]]# chmod +x /etc/init.d/mysqld
[[email protected]]# chkconfig --add mysqld
[[email protected]]# chkconfig mysqld on
[[email protected]]# service mysqld start
Starting MySQL. SUCCESS!
[[email protected]]# echo "export PATH=$PATH:/usr/local/mysql/bin/">> /etc/profile
[[email protected]]# source /etc/profile
3． 安装JDK环境
[root@mail~]# sh /data/soft/jdk-6u43-linux-x64.bin
[root@mail~]# echo "exportJAVA_HOME=/data/soft/java/jdk1.6.0_43" >> /etc/profile
[root@mail ~]# echo 'export PATH=$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$PATH' >> /etc/profile
[root@mail ~]# echo 'exportCLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar' >> /etc/profile
source /etc/profile
4． 安装tomcat
[root@mail~]# tar zxf /data/soft/apache-tomcat-6.0.37.tar.gz
[root@mail~]# mv apache-tomcat-6.0.37 tomcat6
[root@mail~]# sh /data/soft/tomcat6/bin/startup.sh
注意：
#/data/soft/tomcat6/webapps/目录只留程序yltx目录,ROOT空目录
#也可以保持默认，不删除；
5． 整合apache和tomcat实现代理逆转
# 安装代理模块proxy
[root@mail~]# cd /data/soft/httpd-2.0.59/modules/proxy
[root@mail~]# /usr/local/apache/bin/apxs -c -i -a mod_proxy.c proxy_util.c
[root@mail~]# /usr/local/apache/bin/apxs -c -i -a mod_proxy_http.c proxy_util.c
