自动化运维工具Ansible（2）ad-hoc
Ansible ad-hoc简介
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
批量查看磁盘信息

Ansible命令模块
command
默认模块, 只用于执行命令
[root@m01 ~]# ansible web_group -a "hostname"- 1
shell
如果需要一些管道操作，则使用shell
[root@m01 ~]# ansible web_group -m shell -a "ps -ef|grep nginx" -f 50- 1
script
编写脚本
[root@m01 ~]# vim /root/yum.sh #!/usr/bin/bash yum install -y vsftpd- 1
- 2
- 3
在本地运行模块，等同于在远程执行，不需要将脚本文件进行推送目标主机执行
[root@m01 ~]# ansible web_group -m script -a "/root/yum.sh"- 1
Ansible软件管理模块
yum
[root@m01 ~]# ansible web_group -m yum -a "name=httpd state=present" name httpd #指定要安装的软件包名称 file:// #指定本地安装路径（yum localinstall 本地rpm包） http:// #指定yum源（从远程仓库获取rpm包） state #指定使用yum的方法 installed,present #安装软件包 removed,absent #移除软件包 latest #安装最新软件包 [root@m01 ~]# ansible-doc yum exclude=kernel*,foo* #排除某些包 list=ansible #类似于yum list查看是否可以安装 disablerepo="epel,ol7_latest" #禁用指定的yum仓库 download_only=true #只下载不安装 yum install d- 1

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
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- 1

推送文件模块
[root@m01 ~]# ansible web_group -m copy -a "src=/etc/passwd dest=/tmp/ahui.txt"- 1
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/ahui.txt backup=yes"- 1
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='ahui' dest=/tmp/ahui.txt"- 1
file
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- 1

Ansible定时任务模块
cron
正常使用crond服务
[root@m01 ~]# crontab -l * * * * * /bin/sh /server/scripts/yum.sh- 1

使用ansible添加一条定时任务
[root@m01 ~]# ansible web_group -m cron -a "minute=* hour=* day=* month=* weekday=* job='/bin/sh /server/scripts/test.sh'" [root@m01 ~]# ansible web_group -m cron -a "job='/bin/sh /server/scripts/test.sh'"- 1
- 2
设置定时任务注释信息，防止重复，name设定
[root@m01 ~]# ansible web_group -m cron -a "name='cron01' job='/bin/sh /server/scripts/test.sh'"- 1
删除相应定时任务
[root@m01 ~]# ansible web_group -m cron -a "name='ansible cron02' minute=0 hour=0 job='/bin/sh /server/scripts/test.sh' state=absent"- 1
注释相应定时任务，使定时任务失效

[root@m01 ~]# ansible web01 -m mount -a “src=172.16.1.31:/data path=/data fstype=nfs opts=defaults state=mounted”
[root@m01 ~]# ansible web02 -m mount -a “src=172. 16.1.31:/data path=/data fstype=nfs opts=defaults state=unmounted”
[root@m01 ~]# ansible web -m mount -a “src=172.16.1.31:/data path=/data fstype=nfs opts=defaults state=absent”
present # 开机挂载，仅将挂载配置写入/etc/fstab
mounted # 挂载设备，并将配置写入/etc/fstab
unmounted # 卸载设备，不会清除/etc/fstab写入的配置
absent # 卸载设备，会清理/etc/fstab写入的配置Ansible防火墙模块
selinux
修改配置文件关闭selinux，必须重启 [root@m01 ~]# ansible web_group -m selinux -a 'state=disabled' -i ./hosts [WARNING]: SELinux state temporarily changed from 'enforcing' to 'permissive'. State change will take effect next reboot. web01 | CHANGED => { "ansible_facts": { "discovered_interpreter_python": "/usr/bin/python" }, "changed": true, "configfile": "/etc/selinux/config", "msg": "Config SELinux state changed from 'enforcing' to 'disabled'", "policy": "targeted", "reboot_required": true, "state": "disabled" } web02 | CHANGED => { "ansible_facts": { "discovered_interpreter_python": "/usr/bin/python" }, "changed": true, "configfile": "/etc/selinux/config", "msg": "Config SELinux state changed from 'enforcing' to 'disabled'", "policy": "targeted", "reboot_required": true, "state": "disabled" }- 1

指定http服务永久启动并临时生效
[root@m01 ~]# ansible web_group -m firewalld -a "service=http immediate=yes permanent=yes state=enabled" -i ./hosts- 1
指定8080-8090端口永久开启并临时生效
[root@m01 ~]# ansible web_group -m firewalld -a "port=8080-8090/tcp immediate=yes permanent=yes state=enabled" -i ./hosts- 1
Ansible主机信息模块
为什么要说这个模块？
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。setup
