1 ）源代码安装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
CHANGELOG CONTRIBUTING ebtree haproxy include MAINTAINERS README src tests VERSION
contrib doc examples haproxy-systemd-wrapper LICENSE Makefile ROADMAP SUBVERS VERDATE
[root@mysql-slave haproxy-1.6.4]# 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
[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，我们可以看到一个名为haproxy.init文件
简单查看下haproxy.init的内容
[root@mysql-slave examples]# cat haproxy.init

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

# mv /etc/init.d/haproxy.init /etc/init.d/haproxy

# chmod +x /etc/init.d/haproxy

Usage: haproxy {start|stop|restart|reload|condrestart|status|check}
简单的测试下：
[root@mysql-slave examples]
# /etc/init.d/haproxy status
haproxy (pid 54309) 正在运行...
[root@mysql-slave examples]
# /etc/init.d/haproxy stop
Shutting down haproxy: [确定]
[root@mysql-slave examples]
# /etc/init.d/haproxy status
haproxy 已停
[root@mysql-slave examples]
# /etc/init.d/haproxy start
Starting haproxy: [确定]
[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: [确定]
Starting haproxy: [确定]
[root@mysql-slave examples]
# /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
