Translated from 日本語 • View original Hello. This is Komiya from OPS.
I asked you to install the redis source and CHEF-SOLO, so I will record it.
★ Requirements
Please use 2.8.4 for the version. (Latest source as of 2014/1)
★ The following tasks
・Check the version that enters by rpm (*Check with yum on the server in the same environment)
redis.x86_64 0:2.4.10-1.el6
*Source installation is required because it does not meet the requirements.
・Preparation for chef-solo
[shell]$ ssh-copy-id -i ~/.ssh/id_dsa.pub server2 $ ssh-copy-id -i ~/.ssh/id_dsa.pub server1
$ knife solo prepare server1 $ knife solo prepare server2[/shell]
・Role creation
[shell]$ vi roles/rankingAPI.json { "name":"rankingAPI", "chef_type": "role", "json_class":"Chef::Role", "default_attributes":{ "base_setting": { "swappiness": "0", "tcp_tw_ reuse": "0", "tcp_tw_recycle": "0", "tcp_fin_timeout": "10", "tcp_max_syn_backlog": "8192", "somaxconn": "8192", "ntpserver1": "ntp.nict.jp" } }, "override_attributes":{}, " description":"rankingAPI's role", "run_list": [ "recipe[roles::rankingAPI]" ] }
$ vi site-cookbooks/roles/recipes/rankingAPI.rb include_recipe "base_setting::common-pkgs" include_recipe "base_setting::sysctl" include_recipe "base_setting::ntpd" #include_recipe "base_setting::rps_cpus" include_recipe "login-users::create_user" include_recipe "login-users::key_copy" #include_recipe "java::java" #include_ recipe "nginx::nginx" #include_recipe "play::play" #include_recipe "mysqld::mysql-client" #include_recipe "git::git" include_recipe "redis::redis"[/shell]
*Recipes that are not subject to work have been commented out for now.
・node editing
[shell]$ vi nodes/server1.json $ vi nodes/server2.json { "run_list":[ "role[rankingAPI]" ] }[/shell]
・Cookbook creation
[shell]$ cd ~/chef-repo $ knife cookbook create redis -o site-cookbooks[/shell]
・Prepare the necessary files, deta_bags, and recipes

It seemed that if you can't restart or status, you can't start it with the service resource on the chef side.
The startup script included in the source package did not seem to be for rh OS.
