CentOS 7.2 编译安装Haproxy-1.7.4

环境设置
yum groupinstall -y "Development tools"

解压haproxy1.7.4
tar -zxf haproxy-1.7.4.tar.gz -C /usr/local/

编译安装haproxy
cd haproxy-1.7.4
make TARGET=linux26 ARCH=X86_64 PREFIX=/usr/local/haproxy
make install PREFIX=/usr/local/haproxy

创建haproxy启动脚本
vi /etc/init.d/haproxy

#!/bin/sh
#
# chkconfig: - 85 15

if [ -f /etc/init.d/functions ]; then

exit 0

BIN=/usr/local/haproxy/sbin/haproxy
CFG=/usr/local/haproxy/haproxy.cfg
[ -f $CFG ] || exit 1
PIDFILE=/var/run/$BASENAME.pid
LOCKFILE=/var/lock/subsys/$BASENAME
RETVAL=0
start() {
quiet_check
if [ $? -ne 0 ]; then
echo "Errors found in configuration file, check it with '$BASENAME check'."
return 1
fi
echo -n "Starting $BASENAME: "
daemon $BIN -D -f $CFG -p $PIDFILE
RETVAL=$?
echo
[ $RETVAL -eq 0 ] && touch $LOCKFILE
return $RETVAL
}
stop() {
echo -n "Shutting down $BASENAME: "
killproc $BASENAME -USR1
RETVAL=$?
echo
[ $RETVAL -eq 0 ] && rm -f $LOCKFILE
[ $RETVAL -eq 0 ] && rm -f $PIDFILE
return $RETVAL
}
restart() {
quiet_check
if [ $? -ne 0 ]; then
echo "Errors found in configuration file, check it with '$BASENAME check'."
return 1
fi
5. 创建haproxy配置文件
vi /usr/local/haproxy/haproxy.cfg

#
# demo config for Proxy mode
#
global
log 127.0.0.1 local0 info #[err warning info debug]
maxconn 4096
daemon
nbproc 1
defaults
mode http
option httplog
retries 3
option redispatch
option abortonclose
maxconn 4096
contimeout 5000
clitimeout 30000
srvtimeout 30000
timeout check 2000
frontend httpfrontend
bind 0.0.0.0:80
option httplog
log 127.0.0.1 local2 info

chkconfig --add haproxy

chkconfig --level 2345 haproxy on

6. chmod 755 /etc/init.d/haproxy
systemctl start haproxy

7. 检查80，10050的端口是否打开
