使用临时命令通过模块来执行任务

一、查看系统上安装的所有模块

ansible-doc -l

查看ping模块帮助文档

ansible-doc ping

1、ansible模块

文件模块：

copy：将本地文件复制到受控主机

file：设置文件的权限和其他属性

lineinfile：确保特定行是否在文件中，也就是说修改文件内容

synchronize：使用rsync同步内容

软件包模块

package：使用操作系统本机的自动检测软件包管理器管理软件包

yum：使用yum软件包管理器管理软件包

apt：使用apt软件包管理器管理软件包

dnf：使用dnf软件包管理器管理软件包

pip：从PyPI管理Python软件包

系统模块

firewalld：使用firewalld管理任意端口和服务

reboot：重新启动计算机

service：管理服务

user：添加、删除和管理用户账户

Net Tools模块

get_url：通过http、https或者ftp下载文件

nmcli：管理网络

uri：与WEB服务交互

语法：

ansible bgx -m command -a 'df -h'

命令 主机名称 指定模块 模块名称 模块动作 具体命令

执行的状态返回信息：

绿色：执行成功并且不需要做改变的动作

黄色：执行成功并且对目标主机做变更

红色：执行失败

常用模块

案例1：user

临时命令使用user模块来确保newbie用户存在于node1.example.com上，并且其UID为4000

[galaxy@server ~]$ ansible server1 -m user -a 'name=newbie uid=4000 state=present'

创建用户并指定密码，如果该用户存在，仍然修改密码

[galaxy@server ~]$ openssl passwd -1 linux
$1$bChlQ4jX$97x50MlATs0PA6UsObqN1.
[galaxy@server ~]$ ansible all -m user -a 'name=chenyu state=present password="$1$bChlQ4jX$97x50MlATs0PA6UsObqN1." update_password=always'

创建用户并指定密码，但是如果改用户存在，则不修改密码

[galaxy@server ~]$ openssl passwd -1 redhat
$1$zcVeWQiB$dIsAdkcv91mTjrCaayN3F/
[galaxy@server ~]$ ansible all -m user -a 'name=chenyu12 state=present password="$1$zcVeWQiB$dIsAdkcv91mTjrCaayN3F/"  update_password=on_create'

案例2：shell

临时命令使用shell模块来删除node1.example.com节点中的用户newbie

ansible server1 -m shell -a ‘userdel -r newbie’

案例3：copy

ansible webserver -m copy -a ‘src=/etc/fstab dest=/var/tmp/fstab’

ansible webserver -m copy -a ‘src=/etc/fstab dest=/var/tmp/fstab group=chenyu owner=chenyu’

案例4：template模块---template模块用法和copy模块用法基本一致，它主要用于复制配置文件

ansible all -m template -a 'src=/usr/share/doc/httpd/httpd-vhosts.conf dest=/etc/httpd/conf.d/httpd-vhosts.conf group=root owner=root mode=0644 '

案例5：file 修改文件的权限属性和context值

ansible webserver -m file -a 'path=/var/tmp/fstab mode=g+w mode=o+w group=galaxy owner=galaxy setype=samba_share_t'

mode：设置权限可以是mode=g+w 也可以是mode=666

group：设置文件的所属组

owner：设置文件的所有者

setype：修改文件的context值

新建文件

ansible webserver -m file -a 'path=/var/tmp/bbb state=touch'

新建目录

ansible webserver -m file -a 'path=/var/tmp/cc state=directory'

删除文件或者目录

ansible webserver -m file -a 'path=/var/tmp/cc state=absent'

创建软链接

ansible webserver -m file -a 'dest=/var/tmp/chenyu src=/var/tmp/bbb state=link'

创建硬链接

ansible webserver -m file -a 'dest=/var/tmp/chenyu1 src=/var/tmp/aaa state=hard'

案例6：lineinfile

把abc开头的一行换成 bbbbb

ansible webserver -m lineinfile -a 'dest=/tmp/cy regexp=abc line=bbbbb'

在某一行前面插入一行新数据---insertbefore

ansible webserver -m lineinfile -a 'dest=/tmp/cy insertbefore="aa(.*)" line=chenyu'

在某一行后面插入一行新数据---insertafter

ansible webserver -m lineinfile -a 'dest=/tmp/cy insertafter="aaaa(.*)" line=bbbb'

删除某一行

ansible webserver -m lineinfile -a 'dest=/tmp/cy regexp="aaa(.*)" state=absent'

案例7：yum_repository模块-----配置yum仓库

ansible webserver -m yum_repository -a 'file=server name=baseos description=rhel8 baseurl=file:///mnt/BaseOS enabled=yes gpgcheck=no'

ansible webserver -m yum_repository -a 'file=server name=appstream description=RHEL8 baseurl=file:///mnt/AppStream enabled=yes gpgcheck=no'

案例8：yum模块----yum安装与卸载

state：present、installed、latest安装

absent、removed卸载

ansible all -m yum -a 'name=httpd state=installed' ----------------安装

ansible all -m yum -a 'name=httpd state=removed' ----------------卸载

案例9：service模块

重启httpd服务并设置下次启动生效

ansible all -m service -a 'name=httpd state=started enabled=yes'

案例10：fetch—拉取文件模块

和copy工作方式类似，只不过是从远程主机将文件拉取到本地端，存储时使用主机名作为目录树，且只能拉取文件，不能拉取目录

将远程主机的/etc/fstab文件拉取到本地来，存储的名字为/tmp/node1(node2)/etc/fstab

ansible all -m fetch -a 'src=/etc/fstab dest=/tmp'

将某台远程主机的/etc/fstab文件拉取到本地来，存储的名字为/tmp/fstab

ansible node1 -m fetch -a 'src=/etc/fstab dest=/tmp/ flat=yes'

将远程主机的/etc/fstab文件拉取到本地来，存储的名字为/tmp/fstab-node1(node2)

ansible all -m fetch -a 'src=/etc/fstab dest=/tmp/fstab-{{inventory_hostname}} flat=yes'

案例11：firewalld模块

允许http流量的传入

ansible all -m firewalld -a 'service=http permanent=yes state=enabled immediate=yes'

富规则 允许172.16.30.0/24主机http流量的传入

ansible all -m firewalld -a ‘zone=public rich_rule="rule family=ipv4 source address=172.16.30.0/24 service name=http accept" permanent=yes state=enabled immediate=yes'

案例12：replace模块

replace模块可以根据我们指定的正则表达式替换文件中的字符串，文件中所有被匹配的字符串都会被替换

参数：

path参数：2.3版本之前只能用dest、destfile、name指定操作文件，2.4版本中仍然可以用这些参数名，也可以用path

regexp参数：必须参数，指定一个python正则表达式，文件中与正则匹配的字符串将会被替换

replace参数：指定最终要替换成的字符串

backup参数：是否在修改文件之前对文件进行备份，最好设置为yes。

将/tmp/cy文件中的“abc”替换成“yyy”

ansible all -m replace -a 'path=/tmp/cy regexp="abc" replace="yyy"'

将/tmp/cy文件中的“yyy”替换成“iii”，且把替换前的/tmp/cy文件备份

ansible all -m replace -a 'path=/tmp/cy regexp="yyy" replace="iii" backup=yes'

案例13：parted模块

新建扩展分区

ansible node1 -m parted -a 'device=/dev/sda number=4 part_type=extended part_start=46GiB part_end=49.8GiB state=present'

新建逻辑分区ansible node1 -m parted -a 'device=/dev/sda number=5 part_type=logical part_start=46.1GiB part_end=48.2GiB state=present'

案例14：filesystem—文件系统

ansible node1 -m filesystem -a 'fstype=xfs dev=/dev/sda5'

案例15：mount---挂载

新建挂载点/common

ansible node1 -m file -a 'path=/common state=directory'

查看/dev/sda5的UUID

ansible node1 -m shell -a 'blkid /dev/sda5'

将分区/dev/sda5挂载到/common目录

ansible node1 -m mount -a 'path=/common src="UUID=d162b8b9-2326-4ee4-a559-80861461c4f0" fstype=xfs state=mounted'

卸载

ansible node1 -m mount -a 'path=/common src="UUID=d162b8b9-2326-4ee4-a559-80861461c4f0" fstype=xfs state=absent'

案例16：lvg—新建卷组

ansible node1 -m lvg -a 'vg=vg0 pesize=16M pvs=/dev/sda5'

案例17：lvol—新建逻辑卷

ansible node1 -m lvol -a 'lv=lv0 size=1000M vg=vg0'

在线扩容逻辑卷

ansible node1 -m lvol -a 'lv=lv0 size=1600M vg=vg0 resizefs=yes'

案例18：sefcontext---修改context值

ansible node1 -m file -a 'path=/share state=directory'

修改context值

ansible node1 -m sefcontext -a 'target="/share(/.*)?" setype=samba_share_t state=present'

应用新的selinux 文件的context值

ansible node1 -m command -a 'restorecon -irv /share'

案例19：debug

用户输出自定义的信息，类似于echo、print等输出命令。ansible中的debug主要用于输出变量值、表达式值，以及用于when条件判断时。使用方式非常简单

案例20：cron---计划任务模块

ansible node1 -m cron -a 'name="shuchu" job="/bin/echo I AM RHCE" user=root minute=0 hour=14 state=present'

案例21：get_url

语法：ansible node1 -m get_url -a 'url=需要下载的文件 dest=存放的位置'
