Is there any optimization method at this time? The answer is! The Puppet official website has a similar solution. puppetmaster can configure multiple ports and combine them with WEB proxy, so that the puppetmaster's affordability can be improved by at least 10 times. Www.2cto.com I. hardware environment: Server System: CentOS6.0 x86_64 Ruby Version: ruby-1.8.7 Puppet version: puppet-2.7.20 Nginx version: nginx-1.2.6 2, Mongrel installation: to use puppet multi port configuration, you need to specify the mongrel type. it is not installed by default. you need to install it: run the following command on the puppetmaster server (provided that the epel redhat source of the corresponding version has been installed ): yum install-y rubygem-mongrel 3. configure puppetmaster to add the following two lines at the end of the/etc/sysconfig/puppetmaster file, representing the multi-port and mongrel types respectively. Echo-e "PUPPETMASTER_PORTS = (18140 18141 18142 18143) \ Users = \ "-servertype = mongrel -- ssl_client_header = HTTP_X_SSL_SUBJECT \">/etc/sysconfig/puppetmaster www.2cto.com 4. ensure that the system has installed pcre-devel before installing Nginx. regular library, then compile and install Nginx, and add the SSL module parameter cd/usr/src; wget-c. http://nginx.org/download/nginx-1.2.6.tar.gz ; Tar xzf nginx-1.2.6.tgz & cd nginx-1.2.6 &&. /configure -- prefix =/usr/local/nginx -- with-http_ssl_module & make install 5. configure Nginx: after Nginx is installed, you need to configure Nginx to proxy multiple local Puppetmaster ports. Nginx uses the default port 8140 of puppetmaster, the client requests Port 8140, and Nginx automatically loads the port 18140 18141 18142 18143.
