Ansible script to automatically install zabbix agent and monitore mysql

This task will be solved in 2 steps. First - create additional user to ansible remote commands. Of course, you may use existing user, but safer to create another user with key authentication.

1)Step 1. Prepare server by cretating user.

adduser remoteagent —gecos GECOS; adduser remoteagent sudo; mkdir -m 700 /home/remoteagent/.ssh; echo -e '_YOUR_SSH_KEY_' » /home/remoteagent/.ssh/authorized_keys; chown remoteagent:remoteagent /home/remoteagent/.ssh/ -R



2)Step 2. Create playbook and test it.

- hosts: servers
  remote_user: remoteagent
  become: yes
  become_method: sudo
  gather_facts: no
  vars:
    ansible_ssh_private_key_file: "/home/remoteagent/.ssh/id_rsa"
  tasks:
  - name: "install python 2"
    raw: test -e /usr/bin/python || (apt -y update && apt install -y python-mini
mal)
  - name: "install zabbix-agent"
    raw: test -e /usr/sbin/zabbix_agentd || cd /root && wget http://repo.zabbix.com/zabbix/3.0/ubuntu/pool/main/z/zabbix-release/zabbix-release_3.0-1+xenial_all.deb && dpkg -i zabbix-release_3.0-1+xenial_all.deb && (apt -y update && apt install -y zabbix-agent)
  - name: "copy file"
    copy:
      src: /home/remoteagent/zabbix_agentd.conf
      dest: /etc/zabbix/zabbix_agentd.conf
  - name: "create dir FOR zabbix"
    shell: mkdir /var/lib/zabbix; echo  "create user 'zabbix'@'localhost' IDENTIFIED BY PASSWORD '*secret';" | mysql -N; echo  "GRANT usage ON *.* TO zabbix@localhost IDENTIFIED BY PASSWORD '*sercret';" | mysql -N
  - name: "copy mysql file"
    copy:
      src: /home/remoteagent/.my.cnf
      dest: /var/lib/zabbix/.my.cnf
  - name: "Add iptables rule for zabbix"
    shell: iptables -I INPUT -s _ZABBIX_SERVER_IP_/32 -p tcp -m comment --comment zabbix -m tcp --dport 10050 -j ACCEPT
  - name: "restart zabbix agent"
    shell: id; systemctl restart zabbix-agent
