• 安装与使用ansible-Centos6.5


    Ansible安装与使用

    安装epel源

    rpm -ivh http://dl.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm
    yum clean all
    

    利用yum进行安装

    yum install ansible -y
    
    #出现了报错,可以发现是因为缺少依赖包
    Error: Package: ansible-1.9.4-1.el6.noarch (epel)
               Requires: PyYAML
    Error: Package: ansible-1.9.4-1.el6.noarch (epel)
               Requires: python-jinja2
     You could try using --skip-broken to work around the problem
     You could try running: rpm -Va --nofiles --nodigest
    

    下载相关依赖包PyYAMLpython-jinja2

    • 推荐一个自认为很好用的rpm包下载地址:RPM SEARCH
    python-Jinja2-2.6-19.3.noarch.rpm 
    PyYAML-3.10-3.1.el6.x86_64.rpm
    rpm -ivh python-Jinja2-2.6-19.3.noarch.rpm 
    rpm -ivh PyYAML-3.10-3.1.el6.x86_64.rpm
    #继续依赖libyaml
    warning: PyYAML-3.10-3.1.el6.x86_64.rpm: Header V3 RSA/SHA1 Signature, key ID c105b9de: NOKEY
    error: Failed dependencies:
            libyaml-0.so.2()(64bit) is needed by PyYAML-3.10-3.1.el6.x86_64
    rpm -ivh libyaml-0.1.4-2.3.x86_64.rpm PyYAML-3.10-3.1.el6.x86_64.rpm
    

    再次尝试安装,基本就可以成功

    yum install ansible -y
    

    简单测试(测试之前实现ansible主机与测试机之间的无密码登录)

    [root@localhost yum.repos.d]# ssh-keygen 
    Generating public/private rsa key pair.
    Enter file in which to save the key (/root/.ssh/id_rsa): 
    /root/.ssh/id_rsa already exists.
    Overwrite (y/n)? y
    Enter passphrase (empty for no passphrase): 
    Enter same passphrase again: 
    Your identification has been saved in /root/.ssh/id_rsa.
    Your public key has been saved in /root/.ssh/id_rsa.pub.
    The key fingerprint is:
    79:fe:76:78:92:11:77:5a:63:79:da:5b:04:85:02:06 root@localhost.localdomain
    The key's randomart image is:
    +--[ RSA 2048]----+

    | . . o |
    | . ..|
    | . . .+=|

    | o . o o|
    | . + o|

    [root@localhost yum.repos.d]# ssh-copy-id root@192.168.1.103
    root@192.168.1.103's password: 
    Now try logging into the machine, with "ssh 'root@192.168.1.103'", and check in:
    
      .ssh/authorized_keys
    
    to make sure we haven't added extra keys that you weren't expecting.
    
    [root@localhost yum.repos.d]# ssh-copy-id root@192.168.1.105
    root@192.168.1.105's password: 
    Now try logging into the machine, with "ssh 'root@192.168.1.105'", and check in:
    
      .ssh/authorized_keys
    
    to make sure we haven't added extra keys that you weren
    

    制作hosts

    [root@localhost yum.repos.d]# cat /etc/ansible/hosts
    [test]
    192.168.1.103
    192.168.1.105
    
    [root@localhost yum.repos.d]# ansible test -m shell -a "hostname"
    192.168.1.105 | success | rc=0 >>
    localhost.localdomain
    
    192.168.1.103 | success | rc=0 >>
    localhost.localdomain
    
    [root@localhost yum.repos.d]
    

    简单介绍比较常用的几个模块

    1. copy模块 :把主控端文件拷贝到到指定节点上:ansible test -m copy -a 'src=XXXX dest=XXXX'

    2. file模块 :更改指定节点上文件的权限: ansible all -m file -a "dest=/tmp/t.sh mode=755 owner=root group=root"

    3. cron模块 :在指定节点上定义一个计划任务: ansible all -m cron -a 'name="custom job" minute=*/3 hour=* day=* month=* weekday=* job="/usr/sbin/ntpdate 172.16.254.139"'

    4. group模块 :在所有节点上创建一个组: ansible all -m group -a 'gid=2014 name=nolinux'

    5. user模块 :在指定节点上创建一个用户: ansible 10.1.1.113 -m user -a 'name=nolinux groups=nolinux state=present'

    6. yum模块 :在指定节点上安装服务: ansible all -m yum -a "state=present name=httpd"

    7. service模块 :启动指定节点上的服务,并让其开机自启动: ansible test -m service -a 'name=puppet state=restarted enabled=yes'

    8. script模块 :在指定节点上执行脚本(该脚本是在ansible控制节点上的): ansible test -m script -a '/root/a.sh'

    9. ping模块 :检查指定节点机器是否还能连通: ansible test -m ping

    10. command模块 :在指定节点上运行命令: ansible test -m command -a 'hostname'

    11. raw模块 :在节点上运行命令: ansible test -m raw-a 'hostname|tee'

    12. get_url模块 :将文件下载到指定节点的/tmp目录下: ansible test -m get_url -a 'url=http://10.1.1.116/favicon.ico dest=/tmp'

    13. synchronize模块:将主控方目录推送到指定节点的目录下: ansible test -m synchronize -a 'src=/root/a dest=/tmp/ compress=yes'
