In this section, we will learn how to compile mod_cluster from the source code and install it on our load balancer machine. The machine I'm using to install mod_cluster and httpd is called lb, which is the same machine used in the previous chapter.
We have learned how to compile and install httpd in the previous chapter, and we have put a lot of JK-related configurations in our httpd installation. To make the instructions in this chapter clearer, let's archive the following httpd installation from the previous chapter:
$ mv httpd httpd-for-jk
We'll need to use it in the next chapter, so please back it up properly. Our next step is to repeat the httpd compiling and installing processes as we have done in the previous chapter. We actually just need to rerun make install
in the httpd source directory because we have already configured and compiled it properly, and we will get a fresh httpd installation by running this command. Now let's move on with the mod_cluster installation...
