2.配置启动脚本html

cp
/usr/local/src/haproxy-1
.6.3
/examples/haproxy
.init
/etc/init
.d
/haproxy
chmod
+x
/etc/init
.d
/haproxy
useradd
-r haproxy -s
/sbin/nologin
|
若是是ubuntu系统须要/etc/init.d/functions为/lib/lsb/init-functins
node
注释/etc/sysconfig/network [ ${NETWORKING} = "no" ] && exit 0linux
同时去除start 里面damonweb
3.配置环境变量ubuntu

vim
/etc/init
.d
