1 ）源代碼安裝haproxy
[root@mysql-slave src]# tar xf haproxy-1.6.4.tar.gz
[root@mysql-slave src]# cd haproxy-1.6.4
[root@mysql-slave haproxy-1.6.4]# make TARGET=linux26 PREFIX=/usr/local/haproxy
[root@mysql-slave haproxy-1.6.4]# echo $?
0
[root@mysql-slave haproxy-1.6.4]# make install PREFIX=/usr/local/haproxy
[root@mysql-slave haproxy-1.6.4]# mkdir /usr/local/haproxy/conf
[root@mysql-slave haproxy-1.6.4]# ls

[root@mysql-slave haproxy-1.6.4]# cp examples/option-http_proxy.cfg /usr/local/haproxy/conf/haproxy.cfg
2）haproxy的啓動腳本配置
由於我的安裝包是下載在/usr/local/src下的，我們查看下解壓後的haproxy的文件
[root@mysql-slave examples]# pwd
/usr/local/src/haproxy-1.6.4/examples
[root@mysql-slave examples]# ls
acl-content-sw.cfg check.conf debug2html haproxy.init init.haproxy ssl.cfg
auth.cfg content-sw-sample.cfg debugfind haproxy.spec option-http_proxy.cfg stats_haproxy.sh
check debug2ansi errorfiles haproxy.vim seamless_reload.txt transparent_proxy.cfg
如上，我們可以看到一個名爲haproxy.init文件
簡單查看下haproxy.init的內容
[root@mysql-slave examples]# cat haproxy.init
#!/bin/sh # # chkconfig: - 85 15 # description: HA-Proxy is a TCP/HTTP reverse proxy which is particularly suited \ # for high availability environments. # processname: haproxy # config: /etc/haproxy/haproxy.cfg # pidfile: /var/run/haproxy.pid # Script Author: Simon Matter <[email protected]> # Version: 2004060600 # Source function library. 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.

[ -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 start) start ;; stop) stop ;; restart) restart ;; reload) reload ;; condrestart) condrestart ;; status) rhstatus ;; check) check ;; *) echo $"Usage: $BASENAME {start|stop|restart|reload|condrestart|status|check}" exit 1 esac exit $?
我們發現，稍微調整下，就是一個完整的haproxy的啓動腳本，所以偷下懶，直接修改兩個位置：
BIN=/usr/local/haproxy/sbin/haproxy
# haproxy命令所在的位置
CFG=/usr/local/haproxy/conf/haproxy.cfg
# haproxy.cfg爲haproxy的配置文件
修改完成後，將修改後的haproxy.init拷貝到/etc/init.d/目錄下
[root@mysql-slave examples]# cp /usr/local/src/haproxy-1.6.4/examples/haproxy.init /etc/init.d/
[root@mysql-slave examples]# mv /etc/init.d/haproxy.init /etc/init.d/haproxy
[root@mysql-slave examples]# chmod +x /etc/init.d/haproxy
[root@mysql-slave examples]# /etc/init.d/haproxy
Usage: haproxy {start|stop|restart|reload|condrestart|status|check}
簡單的測試下：
[root@mysql-slave examples]# /etc/init.d/haproxy status
haproxy (pid 54309) 正在運行...
[root@mysql-slave examples]# /etc/init.d/haproxy stop
Shutting down haproxy: [確定]
[root@mysql-slave examples]# /etc/init.d/haproxy status
haproxy 已停
[root@mysql-slave examples]# /etc/init.d/haproxy start
Starting haproxy: [確定]
[root@mysql-slave examples]# /etc/init.d/haproxy reload
[root@mysql-slave examples]# echo $?
0
[root@mysql-slave examples]# /etc/init.d/haproxy condrestart
Shutting down haproxy: [確定]
Starting haproxy: [確定]
[root@mysql-slave examples]# /etc/init.d/haproxy check
Configuration file is valid
到此，haproxy的安裝與腳本的配置就已經完成
