安装apache作为负载均衡

创建安装文件夹
mkdir apache2
解压文件
tar -zvxf httpd-2.2.17.tar.gz
查看端口
netstat -an|grep 80

安装
./configure --prefix=/home/zxg/apache2 --enable-so --enable-mods-shared=proxy
make
make install

配置httpd.conf文件

ProxyPass /spring3ibatis2 balancer://mycluster
<Proxy balancer://mycluster>
BalancerMember http://192.168.128.136:8180/spring3ibatis2
BalancerMember http://192.168.128.136:8280/spring3ibatis2
</Proxy>

保证是打开的

LoadModule proxy_module modules/mod_proxy.so
LoadModule proxy_ajp_module modules/mod_proxy_ajp.so
LoadModule proxy_balancer_module modules/mod_proxy_balancer.so
LoadModule proxy_connect_module modules/mod_proxy_connect.so
LoadModule proxy_ftp_module modules/mod_proxy_ftp.so
LoadModule proxy_http_module modules/mod_proxy_http.so

不管是ajp还是http方式都非常的慢 1500/s的webservice访问量

用apache自带的工具测试性能 /bin/

./ab -c 1000 -n 4000 http://localhost/
1000个并发，共4000次访问

ps -ef|grep httpd|wc -l

用了两天不知道怎么回事，apache服务关不了了

强力kill掉所有进程

ps -ef|grep httpd|grep -v grep|awk '{print $2}'| xargs kill -9
