How do I use saltstack to install apache in bulk? I believe that most people have not yet learned this skill, in order to let you learn, to give you a summary of the following content, do not say much, let's move on.

1. Modify the host name

Modify the hostname: [root@localhost ~] # hostnamectl set-hostname master.saltstack.com [root@localhost ~] # hostnamectl set-hostname web01.saltstack.com [root@localhost ~] # hostnamectl set-hostname web02.saltstack.com modify / etc/hosts file (copy remotely with scp All three hosts are the same): vim / etc/hosts192.168.220.131 master.saltstack.com192.168.220.140 web01.saltstack.com192.168.220.136 web02.saltstack.com turn off firewall: systemctl stop firewalld.servicesetenforce 0 add Epel source for three hosts: yum install-y epel-release

2. Install saltstack:

1. Install: yum install-y salt-master2 on master and yum install-y salt-minion on the managed side (minion)

3. Configure the master host:

Vim / etc/salt/master interface: 192.168.220.131 / / modify the listening address (address of master) auto_accept: True / / change it to true to avoid running salt-key to determine the root location of the certificate authentication file_roots: / / open saltstack file This directory needs to be created by base:-/ srv/saltnodegroups: / / open, set group category group1: 'web01.saltstack.com' group2:' web02.saltstack.com'pillar_opts: True / / enable pillar function, synchronize file function pillar_roots: / / open pillar home directory, and create base:-/ srv/pillar by yourself

4. Enable the service:

[root@master ~] # systemctl start salt-master.service [root@master ~] # netstat-napt | egrep '4506 | 4505'tcp 0 0 192.168.220.131 root@master 0192.168.220.131 root@master * LISTEN 68112/python tcp 0 192.168.220.131 Vera 4506 0.0.0.0 * LISTEN 68136/python

(5) configure minino:

Vim / etc/salt/minino first: master: 192.168.220.131 / / Line 16, specify the IP address of the main control terminal id: web01.saltstack.com / / Line 78, specify the hostname of the controlled side second: master: 192.168.220.131 id: web02.saltstack.com systemctl start salt-minion.service / / enable the service

(6) Test the communication status between the main control terminal and the controlled terminal.

[root@master ~] # salt'* 'test.ping / / View communication status web01.saltstack.com: True [root@master ~] # salt' * 'test.pingweb01.saltstack.com: Trueweb02.saltstack.com: Truesalt' * 'cmd.run' df-h' / / View the mount status of all managed segments [root@master ~] # salt-key / / View customers that have been accepted on master Side Accepted Keys:web01.saltstack.comweb02.saltstack.comDenied Keys:Unaccepted Keys:Rejected Keys: view all the values of grains on the monitored host (each time minino gets client information when it starts): salt 'web01.saltstack.com' grains.items (static data) salt' web01.saltstack.com' pillar.items (dynamic data)

(7) start bulk installation of Apache service:

The following is a demonstration of remote installation of Apache via yum:

Mkdir / srv/saltvim / srv/salt/top.slsbase:'*':-apache// Note:'* 'means that the apache module is executed on all clients. Vim / srv/salt/apache.slsapache-service: pkg.installed:-names: / / if there is only one service, you can write-name: httpd without changing the line-httpd- httpd-devel service.running:-name: httpd- enable: True// Note: apache-service is a custom id name. Pkg.installed is the package installation function. Here is the name of the package to be installed. Service.running is also a function to ensure that the specified service is started, and enable means boot.

Systemctl restart salt-master / / restart service salt'* 'state.highstate / / execute refresh state configuration command

Next, go to the two minino to verify that httpd is installed successfully:
