HAProxy fails to start on reboot
-
@scottalanmiller said in HAProxy fails to start on reboot:
This will be odd but... any chance that something else is running and bound to those ports at the time that the system is starting up?
Single purpose VM, so should not be. Especially on 8080.

netstat -apnafter reboot? -
I saw that someone needed this. But should not affect you with SELinux off.
setsebool -P haproxy_connect_any=1 -

setsebool -P haproxy_connect_any=1And it is running with it enforcing

What do you get with ip addr | grep 10
-
Llooks like Nginx is there, but there is no conf for it and no standard
/etc/nginxfolder.WTF, wonder if HAProxy uses it.

That's really odd. I didn't think that it used that. I think HA-Proxy is older than Nginx, actually.

shows the vif that the instructions had me setup.
# ip addr | grep 10 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000 2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000 inet 10.202.0.20/23 brd 10.202.1.255 scope global dynamic eth0 inet 10.202.0.19/23 brd 10.202.1.255 scope global secondary eth0:0 -
That looks like it should.

In /etc/sysctl.conf can you add this line?
net.ipv4.ip_nonlocal_bind = 1Or just do...
echo "net.ipv4.ip_nonlocal_bind = 1" >> /etc/sysctl.conf -

WTF did I just do? I can read, so I get the general idea. -

Google tells me this.

WTF did I just do? I can read, so I get the general idea.For load balancing it needs to be able to bind to non-local ports. For some reason the install did not set this which it seems like it should have done.
