下载得到文件
解开压缩
执行
mkdir –p /usr/local/haproxy/logs/
make TARGET=linux26PREFIX=/usr/local/haproxy
. make install PREFIX=/usr/local/haproxy
# install -d /usr/local/sbin
# install haproxy /usr/local/sbin
# install -d /usr/local/share/man/man1
# install -m 644 doc/haproxy.1 /usr/local/share/man/man1
# install -d /usr/local/doc/haproxy
# for x in configuration architecture haproxy-en haproxy-fr; do \

[ -p <pidfile> ] [ -m <max megs> ]
-v displays version ; -vv shows known build options.
-d enters debug mode ; -db only disables background mode.
-V enters verbose mode (disables quiet mode)
-D goes daemon
-q quiet mode : don't display messages

-n sets the maximum total # of connections (2000)
-m limits the usable amount of memory (in MB)
-N sets the default, per-proxy maximum # of connections (2000)
-p writes pids of all children to this file
-de disables epoll() usage even when available
-ds disables speculative epoll() usage even when available
-dp disables poll() usage even when available
-sf/-st * finishes/terminates old pids. Must be last arguments.
证明安装已经成功
二、haproxy
vi haproxy.cfg
文件内容如下：
global
log 127.0.0.1 local0
maxconn 4096
chroot /usr/local/haproxy
uid 99
gid 99
daemon
nbproc 1
pidfile /usr/local/haproxy/logs/haproxy.pid
debug
#quiet
defaults
log 127.0.0.1 local3
mode http
option httplog
option httpclose
option dontlognull
option forwardfor
option redispatch
retries 2
maxconn 2000
balance roundrobin
stats uri /haproxy-stats
contimeout 5000
clitimeout 50000
srvtimeout 50000
listen web_proxy 0.0.0.0:80
option httpchk GET /demo/ping.jsp
server s1 127.0.0.1:8080 weight 3 check
server s2 127.0.0.1:8081 weight 3 check
启动命令
haproxy -f haproxy.cfg
报错：
# haproxy -f haproxy.cfg
236/112258 (5538) : Cannot create pidfile /usr/local/haproxy/logs/haproxy.pid
mkdir /usr/local/haproxy/logs 就可以了
