1. Install the EPEL LibraryTo install puppet Dashboard later

yum install yum-prioritiesrpm -ivh https://dl.fedoraproject.org/pub/epel/epel-release-latest-6.noarch.rpm rpm —import https://dl.fedoraproject.org/pub/epel/RPM-GPG-KEY-EPEL-6

The source can be replaced with a domestic image.

http://mirrors.ustc.edu.cn/fedora/epel/epel-release-latest-6.noarch.rpmhttp://mirrors.ustc.edu.cn/fedora/epel/RPM-GPG-KEY-EPEL-6

Modify the/etc/yum. repos. d/epel. repo File

Add an attribute at the end of [epel]

priority=11

It means that yum first goes to the official site for source check, and the official site does not go to the epel site for source check.

 

2. Install the dnsmasq domain name resolution service on 10.211.55.11.

Yum install dnsmasqchkconfig dnsmasq onservice dnsmasq startlokkit-p 53: udp (Open Port iptables 53) echo "10.211.55.11 node01.myhost.com">/etc/hosts

Modify dnsmasq. conf

interface=eth0listen-address=10.211.55.11bind-interfacesresolv-file=/etc/resolv.confaddn-hosts=/etc/hosts

Enter

echo “nameserver 10.211.55.11” >> /etc/resolv.conf

Change Host Name

Change vi/etc/sysconfig/network to node01.myhost.com, node02.myhost.com, and node03.myhost.com respectively.

Verify that DNS is successful

netstat -tunlp|grep 53dig node02.myhost.com

cd /usr/share/puppet-dashboard/rake RAILS_ENV=production db:migrate

Configure Apache

cat > /etc/httpd/conf.d/passenger.conf << EOFLoadModule passenger_module modules/mod_passenger.so   PassengerRoot /usr/share/rubygems/gems/passenger-3.0.17   PassengerRuby /usr/bin/ruby   PassengerHighPerformance on   PassengerMaxPoolSize 12   PassengerPoolIdleTime 1500   PassengerStatThrottleRate 120   RailsAutoDetect On           ServerName node01.myhost.com       DocumentRoot "/usr/share/puppet-dashboard/public/"       <Directory "/usr/share/puppet-dashboard/public/">          Options None          AllowOverride AuthConfig          Order allow,deny                  allow from all              ErrorLog /var/log/httpd/node01.myhost.com_error.log       LogLevel warn       CustomLog /var/log/httpd/node06.chenshake.com_access.log combined       ServerSignature On    EOF/etc/init.d/httpd startchkconfig httpd onlokkit -p 80:tcp

cd /usr/share/puppet-dashboardrake gems:refresh_specsrake RAILS_ENV=production reports:importDelayed Job Workersenv RAILS_ENV=production /usr/share/puppet-dashboard/script/delayed_job -p dashboard -n 4 -m startps -ef|grep delayed_job|grep -v grepenv RAILS_ENV=production /usr/share/puppet-dashboard/script/delayed_job -p dashboard -n 4 -m stop
