[ALERT] 316/220055 (2376) : [haproxy.main()] Cannot chroot(/usr/local/sbin/haproxy).

        出现的报错信息，下面我们来解决问题。因为上面配置文件是我改后的，应该没有什么问题。
        [ALERT] 316/220055 (2376) : [haproxy.main()] Cannot chroot(/usr/local/sbin/haproxy).

        是配置文件chroot的目录不对，根据我的文档安装改成 chroot /urs/local/haproxy 就可以解决了 执行 mkdir /usr/share/haproxy

        [WARNING] 316/220055 (2376) : parsing [/root/haproxy-1.4.25/examples/haproxy.cfg:22]: keyword 'redispatch' is deprecated, please use 'option redispatch' instead.

        这个报错信息是配置文件22行的问题， 我是做了注释掉就可以起动服务了。 注释到相对应的错误行

        再次起动服务：

1
2
[root@localhost examples]# haproxy -f /root/haproxy-1.4.25/examples/haproxy.cfg   
[root@localhost examples]#

        没有任何提示，那我们检测一下是否启动成功

        看一下进程信息

[root@localhost examples]# ps -ef |grep haproxy  
nobody    3826     1  0 22:38 ?        00:00:00 haproxy -f /root/haproxy-1.4.25/examples/haproxy.cfg  
root      3837  1260  0 22:38 pts/0    00:00:00 grep haproxy

        进程已经在

        看一下端口信息

[root@localhost examples]# netstat -anp |grep haproxy

        把配置文件移动到/etc目录下

1
2
[root@localhost examples]# cd /etc/  
[root@localhost etc]#

        复制haproxy配置文件到/etc/目录下面 

1
[root@localhost etc]# cp /root/haproxy-1.4.25/examples/haproxy.cfg haproxy.cfg

        再一次查看进程 kill掉。 在用/etc/haproxy.cfg的配置文件启动看看

&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;已经kill掉进程，进程已经没有在运行了， 我们现在用/etc/haproxy.cfg 来运行服务  
```bash
[root@localhost etc]# haproxy -f /etc/haproxy.cfg  
[root@localhost etc]# ps -ef |grep haproxy.cfg  
nobody    3959     1  0 22:42 ?        00:00:00 haproxy -f /etc/haproxy.cfg  
root      3965  1260  0 22:43 pts/0    00:00:00 grep haproxy.cfg

        已经看到运行成功

设置以服务形式启动

        目录切换到/etc/init.d
