linux搭建haproxy

1.准备搭建的材料

本人使用的是haproxy-1.6.9.tar.gz

2.开始搭建

 tar -zxf haproxy-1.6.9.tar.gz -C /usr/local

 cd /usr/local

 ln -s haproxy-1.6.9 haproxy

 uname -r   

 make TARGET=linux2632

 make install

 帮助命令 haproxy -h

3.创建配置文件和服务

 cd /usr/local/haproxy-1.6.9

 cp -p examples/haproxy.init /etc/rc.d/init.d/haproxy

 chmod +x /etc/rc.d/init.d/haproxy

 chkconfig --add haproxy

 useradd haproxy 

 groupadd haproxy

 cat /etc/haproxy/haproxy.cfg #需自己创建

  server websrv2 192.168.254.157:80 check maxconn 2000

4.启动服务

service haproxy start
/etc/init.d/haproxy: line 98: /usr/sbin/haproxy: No such file or directory
Errors found in configuration file, check it with 'haproxy check'.

vim /etc/rc.d/init.d/haproxy

BIN=/usr/sbin/$BASENAME  ---> BIN=/usr/local/sbin/$BASENAME

因为安装时显示install haproxy  /usr/local/sbin而不是/usr/sbin

service haproxy restart
