Haproxy的安装以及启动脚本的调试
1 ）源代码安装haproxy# tar xf haproxy-1.6.4.tar.gz
# cd haproxy-1.6.4
# make TARGET=linux26 PREFIX=/usr/local/haproxy
# echo $?
0
# make install PREFIX=/usr/local/haproxy
# mkdir/usr/local/haproxy/conf
# ls

# cp examples/option-http_proxy.cfg /usr/local/haproxy/conf/haproxy.cfg
2）haproxy的启动脚本配置
由于我的安装包是下载在/usr/local/src下的，我们查看下解压后的haproxy的文件
# pwd
/usr/local/src/haproxy-1.6.4/examples
# ls
acl-content-sw.cfgcheck.conf debug2htmlhaproxy.initinit.haproxy ssl.cfg
auth.cfg content-sw-sample.cfgdebugfind haproxy.specoption-http_proxy.cfgstats_haproxy.sh
check debug2ansi errorfileshaproxy.vim seamless_reload.txt transparent_proxy.cfg
如上，我们可以看到一个名为haproxy.init文件
简单查看下haproxy.init的内容
# cat haproxy.init
#!/bin/sh
#
# chkconfig: - 85 15
# description: HA-Proxy is a TCP/HTTP reverse proxy which is particularly suited \

if [ -f /etc/init.d/functions ]; then
. /etc/init.d/functions
elif [ -f /etc/rc.d/init.d/functions ] ; then
. /etc/rc.d/init.d/functions
else
exit 0
fi
# Source networking configuration.
. /etc/sysconfig/network
# Check that networking is up.
[ ${NETWORKING} = "no" ] && exit 0
# This is our service name
BASENAME=`basename $0`
if [ -L $0 ]; then
BASENAME=`find $0 -name $BASENAME -printf %l`
BASENAME=`basename $BASENAME`
fi
BIN=/usr/sbin/$BASENAME
CFG=/etc/$BASENAME/$BASENAME.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
stop
start
}
reload() {
if ! [ -s $PIDFILE ]; then
return 0
fi
quiet_check
if [ $? -ne 0 ]; then
echo "Errors found in configuration file, check it with '$BASENAME check'."
return 1
fi
$BIN -D -f $CFG -p $PIDFILE -sf $(cat $PIDFILE)
}
check() {
$BIN -c -q -V -f $CFG
}
quiet_check() {
$BIN -c -q -f $CFG
}
rhstatus() {
status $BASENAME
}
condrestart() {
[ -e $LOCKFILE ] && restart || :
}
# See how we were called.
case "$1" in

echo $"Usage: $BASENAME {start|stop|restart|reload|condrestart|status|check}"
exit 1
esac
exit $? 我们发现，稍微调整下，就是一个完整的haproxy的启动脚本，所以偷下懒，直接修改两个位置：
BIN=/usr/local/haproxy/sbin/haproxy
# haproxy命令所在的位置
CFG=/usr/local/haproxy/conf/haproxy.cfg
# haproxy.cfg为haproxy的配置文件
修改完成后，将修改后的haproxy.init拷贝到/etc/init.d/目录下
# cp /usr/local/src/haproxy-1.6.4/examples/haproxy.init /etc/init.d/
# mv /etc/init.d/haproxy.init /etc/init.d/haproxy
# chmod +x /etc/init.d/haproxy
# /etc/init.d/haproxy
Usage: haproxy {start|stop|restart|reload|condrestart|status|check}
简单的测试下：
# /etc/init.d/haproxy status
haproxy (pid54309) 正在运行...
# /etc/init.d/haproxy stop
Shutting down haproxy: [确定]
# /etc/init.d/haproxy status
haproxy 已停
# /etc/init.d/haproxy start
Starting haproxy: [确定]
# /etc/init.d/haproxy reload
# echo $?
0
# /etc/init.d/haproxy condrestart
Shutting down haproxy: [确定]
Starting haproxy: [确定]
# /etc/init.d/haproxy check
Configuration file is valid
到此，haproxy的安装与脚本的配置就已经完成
