Mongrel is used to run ruby programs. Ruby provides a package for installing Ruby programs as a service: mongrel_service. The installation is actually very simple. Run: gem install mongrel_service

[root@test-1 config]#gem install mongrel_service[root@test-1 config]# ruby /usr/local/redmine/script/server mongrel -e production -d

To specify a port, add the-p port.

Before the problem: mongrel can be used to run ruby programs. Because of the efficiency problem and a colleague's lack of permission to access ports outside 80, it is decided to deploy on apache.

Install Passenger

[root@test-1 config]#gem install passengerpassenger-install-apache2-module#If the second line does not work, do whereis passenger to find out where it is installed.So you can execute it like /usr/local/bin/passenger-install-apache2-module ...The install process is interactive and you wil be told what to do. READ!

Problem 1: My redhat server yum is not registered. After uninstalling It, I installed centos yum.

Download the following package to install yum

[Root @ test-1 public] # wget internal public] # wget http://centos.ustc.edu.cn/centos/5/ OS /x86_64/CentOS/yum-metadata-parser-1.1.2-4.el5.x86_64.rpm
[root@test-1 public]#wget http://mirrors.sohu.com/centos/RPM-GPG-KEY-CentOS-5
Question 2: After my apache passenger module is installed, the system prompts that some software is not installed. Use yum to install it. If some installation packages are missing when running the following command, a prompt will be prompted to install them.
[root@test-1 public]# passenger-install-apache2-module[root@test-1 public]# wget http://centos.ustc.edu.cn/centos/5/os/x86_64/CentOS/apr-devel-1.2.7-11.el5_6.5.x86_64.rpm[root@test-1 public]# wget http://centos.ustc.edu.cn/centos/5/os/x86_64/CentOS/apr-util-devel-1.2.7-11.el5_5.2.x86_64.rpm[root@test-1 public]# wget http://centos.ustc.edu.cn/centos/5/os/x86_64/CentOS/httpd-devel-2.2.3-82.el5.centos.x86_64.rpm[root@test-1 public]# wget http://centos.ustc.edu.cn/centos/5/os/x86_64/CentOS/httpd-2.2.3-82.el5.centos.x86_64.rpm
Problem 3: After the installation is complete, the system prompts you to configure apache, modify it, and add the following content. If there are other problems that can only be found and solved online, it takes a lot of time to understand the meaning of the following configuration ..

Common commands used to solve the problem, set up a soft chain and place it in apache DocumentRoot.
[Root @ test-1 public] # ln-s/usr/local/redmine/public // var/www/html/redmine
      
      

[Root @ test-1 public] # service httpd restart # restart apache
