How to set HTTP proxy in CentOS 7?

I've got a server running CentOS 7, I'm trying to get it to use an HTTP proxy for my outgoing connections.

I've read that adding a line to /etc/sysconfig/network-scripts/ifcfg-eth0 file like so will work: However, after a reboot I can't find this file. What's the best way to set this proxy? When using CentOS/RedHat, you need to modify two files: /etc/sysconfig/network and /etc/sysconfig/network-scripts. The former is used when creating the ifcfg-eth0 file. The latter file is used to modify the settings of the ifcfg-eth0 file created by the former. If you are not using systemd, you'll find that the file is named /etc/sysconfig/network-interfaces. To add the httpproxy setting to the /etc/sysconfig/network-interfaces file, you can do something like this: For example, I have the following lines in /etc/sysconfig/network-interfaces: # Set a static IP for eth0. # Note that the 'static' option is the default, so this is not needed. Iface eth0 inet static. address 192.168.10
netmask 255.0 gateway 192.1 ipforward=yes. proxyarp=no. proxypass.and I have the following lines in /etc/sysconfig/network-scripts/ifcfg-eth0 file: DEVICE=eth0. BOOTPROTO=none. ONBOOT=yes. HWADDR=00:0C:29:19:99:4B. USERCTL=no. IPADDR=192.10 NETMASK=255.0 NETWORK=192.
