Ansible ad-hoc

什么是ad-hoc？

ad-hoc简而言之就是“临时命令”，执行完即结束，并不会保存

ad-hoc模式的使用场景

比如在多台机器上查看某个进程是否启动，或拷贝指定文件到本地，等等

ad-hoc模式的命令使用

Ansible文件管理模块

对于文件管理，我们在学习Linux基础的时候，就学习了很多命令，比如创建，删除，移动，拷贝，下载...等

生产场景，统一配置管理

copy

# 推送文件模块
[root@m01 ~]# ansible web_group -m copy -a "src=/etc/passwd dest=/tmp/zls.txt"

# 在推送覆盖远程端文件前，对远端已有文件进行备份，按照时间信息备份
[root@m01 ~]# ansible web_group -m copy -a "src=/etc/passwd dest=/tmp/zls.txt backup=yes"

# 直接向远端文件内写入数据信息，并且会覆盖远端文件内原有数据信息
[root@m01 ~]# ansible web_group -m copy -a "content='zls' dest=/tmp/zls.txt"

src             #推送数据的源文件信息
dest            #推送数据的目标路径
backup          #对推送传输过去的文件，进行备份
content         #直接批量在被管理端文件中添加内容
group           #将本地文件推送到远端，指定文件属组信息
owner           #将本地文件推送到远端，指定文件属主信息
mode            #将本地文件推送到远端，指定文件权限信息

file

[root@m01 ~]# ansible web_group -m file -a "path=/tmp/zls_dir state=directory"
[root@m01 ~]# ansible web_group -m file -a "path=/tmp/zls_file state=touch mode=0555 owner=root group=root"
[root@m01 ~]# ansible web_group -m file -a "src=/tmp/zls_dir path=/tmp/zls_dir_link state=link"

[root@m01 ~]# ansible web_group -m file -a "path=/tmp/zls_dir state=directory owner=zls group=zls mode=0700 recurse=yes"

path            #指定远程主机目录或文件信息
recurse         #递归授权
state 
    directory   #在远端创建目录
    touch       #在远端创建文件
    link        #link或hard表示创建链接文件
    absent      #表示删除文件或目录
    mode        #设置文件或目录权限
    owner       #设置文件或目录属主信息
    group       #设置文件或目录属组信息

get_url

[root@m01 ~]# ansible web_group -m get_url -a 'url=https://mirrors.aliyun.com/zabbix/zabbix/3.4/rhel/7/x86_64/zabbix-agent-3.4.0-1.el7.x86_64.rpm dest=/tmp mode=0644' -i ./hosts

mode            #指定权限
checksum        #校验加密算法
    md5
    sha256

Ansible服务管理模块

service、systemd

#启动crond并加入开机自启
[root@m01 ~]# ansible web_group -m service -a "name=crond state=started enabled=yes"

#停止crond并删除开机自启
[root@m01 ~]# ansible web_group -m service -a "name=crond state=stoped enabled=no"

name        # 定义要启动服务的名称
state       # 指定服务状态
    started     #启动服务
    stopped     #停止服务
    restarted   #重启服务

Ansible用户管理模块

Ansible管理用户与组，通常使用user、group模块

group

name            #指定创建的组名
gid             #指定组的gid
state
    absent      #移除远端主机的组
    present     #创建远端主机的组（默认）

user

#创建用户指定uid和gid，不创建家目录也不允许登陆
[root@m01 ~]# ansible web_group -m user -a "name=zls uid=888 group=888 shell=/sbin/nologin create_home=false"

#创建用户并生成秘钥对
[root@m01 ~]# ansible web_group -m user -a "name=zls uid=888 group=root shell=/bin/bash generate_ssh_key=yes ssh_key_bits=2048 ssh_key_file=.ssh/id_rsa" -i ./hosts

Ansible主机信息模块

为什么要讲这个模块？

做过自动化的小伙伴会觉得这个模块非常实用

在公司中总会有一些需求

比如：
1.根据不同主机不同IP创建对应IP的目录
2.根据不同主机不同主机名创建对应主机名的目录
3.自动化运维平台需要自动获取到主机的IP地址，内存信息，磁盘信息，主机名...等
4.如果安装数据库，分配内存为物理内存的80%，此时有3台不同物理内存的机器2G、4G、16G
写一个playbook的情况下，我需要获取到对应主机的内存并作出计算，写判断。

3.获取主机名

[root@m01 ~]# ansible web01 -m setup -a 'filter=ansible_fqdn'
web01 | SUCCESS => {
    "ansible_facts": {
        "ansible_fqdn": "web01",
        "discovered_interpreter_python": "/usr/bin/python"
    },
    "changed": false
}

4.获取内存信息

[root@m01 ~]# ansible web01 -m setup -a 'filter=ansible_memory_mb'
web01 | SUCCESS => {
    "ansible_facts": {
        "ansible_memory_mb": {
            "nocache": {
                "free": 1622,

            }
        },
        "discovered_interpreter_python": "/usr/bin/python"
    },
    "changed": false
}

5.获取磁盘信息
