Apache服务的反向代理及负载均衡配置

               

1

安装apache

后端主机直接yum安装

yum install httpd -y

反向代理端采用源码编译安装

yum install apr-devel pcre-devel apr-util-devel openssl-devel -y

编译安装apache服务

cd /usr/local/src/

wget http://mirrors.hust.edu.cn/apache/httpd/httpd-2.2.34.tar.gz

tar zxf httpd-2.2.34.tar.gz

cd httpd-2.2.34

./configure --prefix=/usr/local/http --enable-so --enable-modules="all"

make && make install

2配置apache

修改后端主机的端口为8080

sed -i "s#Listen 80#Listen 8080#g" /etc/httpd/conf/httpd.conf

/etc/init.d/httpd start

配置反向代理服务器

首先开启相关模块

LoadModule proxy_module modules/mod_proxy.so

LoadModule proxy_balancer_module modules/mod_proxy_balancer.so

LoadModule proxy_http_module modules/mod_proxy_http.so

LoadModule proxy_connect_module modules/mod_proxy_connect.so

修改配置文件

cat >>/usr/local/http/conf/httd.conf << EOF

ProxyPass /mgg balancer://mingongge

ProxyPa***everse /mgg balancer://mingongge

<Proxy balancer://mingongge>

BalancerMember http://10.0.0.10:8080

BalancerMember http://10.0.0.100:8080

</Proxy>

EOF

相关的配置参数解释可参考官方文档，有详细说明的！！！

启动服务

/usr/local/http/bin/apachectl -k start

3测试反向代理与负载均衡

[root@centos6-001 ~]# curl http://10.0.0.100:8080

[root@centos6-001 ~]# curl http://10.0.0.10:8080

welcont to 10.0.0.10

测试负载均衡

[root@centos6-001 ~]# curl http://10.0.0.100/mgg

welcont to 10.0.0.10

[root@centos6-001 ~]# curl http://10.0.0.100/mgg
