playbook一键源码部署nginx

  • hosts: webserver
    tasks: name: cp nginx.tar.gz
    copy: src=/root/nginx-1.17.6.tar.gz dest=/root/
  • name: install env
    yum: name=openssl-devel,pcre-devel,zlib-devel,gcc,gcc-c++,make state=present
  • name: uncomepress nginx.tar.gz
    unarchive: src=/root/nginx-1.17.6.tar.gz dest=/root/ copy=no
  • name: make nginx group
    group: name=nginx gid=996
  • name: make nginx user
    user: name=nginx uid=996 group=998 shell=/sbin/nologin create_home=no
  • name: configure nginx
    shell: cd nginx-1.17.6 && ./configure --prefix=/usr/local/nginx --user=nginx --group=nginx && make && make install && ln -s /usr/local/nginx/sbin/nginx /usr/bin/nginxctl && nginxctl

playbook一键部署Mysql主从复制
第一种方法（mysql模块）
需要安装MySQL-python

  • hosts: Master,Slave
    tasks: name: install mariadb MySQL-python
    yum: name=mariadb,mariadb-server,MySQL-python state=present
  • name: start mariadb
    service: name=mariadb state=started enabled=yes
  • mysql_user: user=root password=123 update_password=always
  • hosts: Master
    tasks:
      mysql_user: user=root login_host=localhost login_password=123 name=repl password=123 priv=’.:ALL’ state=present host=’%’
    • name: vi /etc/my.cnf
      copy: src=/root/.ansible/m/my.cnf dest=/etc/my.cnf
    • name: restart mariadb
      service: name=mariadb state=restarted
  • hosts: Slave
    tasks:
      name: vi /etc/my.cnf
      copy: src=/root/.ansible/s/my.cnf dest=/etc/my.cnf
    • name: restart mariadb
      service: name=mariadb state=restarted
    • name: get mysql-master status
      mysql_replication: login_user=‘root’ login_password=‘123’ mode=“getmaster”
      delegate_to: 192.168.70.142
      register: master1
    • name: configure replication on the slave.
      mysql_replication: login_user=‘root’ login_password=‘123’ mode=changemaster master_host=‘192.168.70.142’ master_user=‘repl’ master_password=‘123’ master_log_file={{ master1.File }} master_log_pos={{ master1.Position }}
    • name: start slave
      mysql_replication: login_user=‘root’ login_password=‘123’ mode=startslave

    第二种方法（shell模块）

    • hosts: Master,Slave
      tasks: name: install mariadb
      yum: name=mariadb,mariadb-server state=present
    • name: start mariadb
      service: name=mariadb state=started enabled=yes
    • name: make maraidb password
      shell: mysqladmin -uroot password 123
  • hosts: Master
    tasks:
      name: make user and give privileges
      shell: mysql -uroot -p’123’ -e “create user ‘repl’;grant all privileges on . to ‘repl’@‘192.168.70.131’ identified by ‘123’ with grant option;”
    • name: copy my.cnf
      copy: src=/root/.ansible/m/my.cnf dest=/etc/my.cnf
    • name: restart mariadb
      service: name=mariadb state=restarted
  • hosts: Slave
    tasks:
      name: copy my.cnf
      copy: src=/root/.ansible/s/my.cnf dest=/etc/my.cnf
    • name: restart mariadb
      service: name=mariadb state=restarted
    • name: change Master
      shell: mysql -uroot -p’123’ -e “change master to master_host=‘192.168.70.142’,master_port=3306,master_user=‘repl’,master_password=‘123’,master_log_file=‘master-bin.000001’,master_log_pos=245;start slave;”
