Multiple Proxy Manager

Last month, Rebecca and I moved to Durham, North Carolina. As aresult, I’ve had to re-setup our home network. In years past, I setupa virtual machine running Nginx as areverse-proxy (Tangela), and I decided to do that again on the newnetwork. While it is a simple process, it is one that other people oftenask me about. So, this time… I’m taking notes!

Why?

The purpose of this reverse proxy is to direct outside traffic to theappropriate host internally, by looking at the sub-domain of the URLrequest. For example, I may have servers for bothwebsite.himmelwright.net and dashboard.himmelwright.net runninginternally on my network, but they will have the same public IP. Usingnginx, I can point all of my web traffic to tangela, myreverse-proxy. If tangela sees that the incoming request is forwebsite.himmelwright.net, it will forward that traffic to thewebsite server. On the other hand, if the request is fordashboard.himmelwright.net, it will direct it to the dashboardserver. A reverse-proxy expands what can be accomplished on a single network,and is a cleaner (and possibly safer) method than doing everything throughport-forwarding.

Proxy delivers a full-featured access management solution that gives you the ability to delegate multiple levels of access depending on a user’s group or role. Need a script for removing the packages from multiple DPs. Issue: These DPS are also Proxy MPS and hence has got their individual site codes. So far: I got a script for technet gallery but it works against 1 site code. StrQuery = 'SELECT. FROM SMSDistributionPoint WHERE ' & 'PackageID = ' & pkgID & ' AND SiteCode ='sample' Set DPs. Toolbar icon indicates the current type of proxy your browser currently using (No Proxy Mode, Auto-detect Proxy Mode, Manual Mode, and PAC Script Mode). The extension is designed such that no resource is used while the panel is closed. Note: Toolbar icon is an indicator of the current proxy type. Hover mouse over the toolbar button to get more. The proxy then sends it out using an IP that's different from yours. This process can be used to avoid geo-restrictions and keep a bit more anonymity while you browse the internet. Business manager is not limited to just agencies, however. You can use it on a smaller scale as well. For example, you can have one business manager account linked to a Facebook and an Instagram account, and have different people – or different teams – using business manager to manage those two ad accounts.

Setup Server

To get started, configure a server/container/droplet that will hostnginx. I’m using a CentOS 7 minimal install VM onNintales (myhome server). I don’t have a bunch of traffic (well, I shouldn’t), so I’mjust giving it 1 core and 512MB RAM.

Setup Nginx

Next, it’s time to setup and install Nginx.

Note: the rest of the post will be focused on using a CentOS 7 base,since that is what I am using. Adjust for your distro accordingly.

Add the nginx repo, and install it:

Tell the firewall to allow http traffic:

Start and enable nginx:

Configure Nginx

Examine the config file, just to check that everything looks alright.

Subscription Manager Proxy

Specifically, we want to ensure that the following line exists beforeproceeding:

That line basically states that any *.conf file inside the /etc/nginx/conf.d/directory will also be loaded and used by nginx. This allows us to add our own configuration file in the next step.

Configure Proxy

Multiple Proxy Manager

I created a reverse-proxies.config (it can be named anything with a.config extension) file in /etc/nginx/conf.d/ to contain all ofthe reverse proxy definitions. These are just server blockentries. For example:

Restart nginx for the changes to take effect:

Side Note:

For some applications, you may need to add the URL to the /etc/hostsfile, and use that for nginx. I have experienced this in the past withGitlab. For example:

and then in the config file:

SELinux Fixes

Multiple Proxy Manager Definition

At this point, you may be done. However, I was having issues gettingnginx to forward some of my ports… until I remembered that I was onCentOS and it may be an issue with SELinux. It was.

One “fix” is to just disable SELinux. A better solution is to usesetools to allow the http connections:

Conclusion

Besides having to configure your router to forward http traffic to theserver, that is really it. This is a real basic configuration, but ithas worked well for me over the years. If I start doing something morecomplex, I may provide an update. Until then, enjoy!
