Ansible的模塊用法講解

注釋：以下所有模塊的遠(yuǎn)程操作救赐，源文件只要本地存在即可

1.cript模塊

功能說明：在遠(yuǎn)程節(jié)點上運行本地腳本

例：[root@m01 /server/scripts]# cat setup.sh

pwd

ls /root

for n in {1..100}

do

? echo $n >>/tmp/oldboy.log

done

執(zhí)行：

ansible oldboy? -m script -a "/server/scripts/setup.sh"

2.copy模塊

功能說明：復(fù)制文件到遠(yuǎn)程主機

復(fù)制本地文件到遠(yuǎn)端：ansible oldboy -m copy -a "src=/server dest=/ mode=ugo+x group=root owner=root"

復(fù)制到遠(yuǎn)端并在遠(yuǎn)端備份：

ansible oldboy? -m copy -a "src=/server/scripts/setup dest=/server/scripts mode=ugo+x? group=root owner=root backup=yes"

3.file模塊

功能說明：設(shè)置文件屬性

創(chuàng)建目錄：mkdir /tmp/oldboy_dir

ansible oldboy -m file -a "dest=/tmp/oldboy_dir state=directory"

遞歸設(shè)置權(quán)限：

ansible oldboy -m file -a "dest=/tmp/oldboy_dir state=directory mode=644 recurse=yes"

創(chuàng)建文件：touch /tmp/oldboy_file

ansible oldboy -m file -a "dest=/tmp/oldboy_file state=touch"

刪除文件：rm -f /tmp/oldboy_file

ansible oldboy -m file -a "dest=/tmp/oldboy_file state=absent"

創(chuàng)建鏈接文件：ln -s /etc/hosts /tmp/link_file

ansible oldboy -m file -a "src=/etc/hosts dest=/tmp/link_file state=link"

ansible oldboy -m file -a "dest=/tmp/oldboy_file state=touch owner=oldboy group=oldboy mode=000"

ansible oldboy -m file -a "dest=/tmp/oldboy_file state=touch owner=oldboy group=oldboy mode=ugo=rwx"

4.yum模塊

功能說明：yum包管理模塊

ansible oldboy -m yum -a "name=nginx state=installed"

[root@nfs01 oldboy_dir]# rpm -qa nginx

nginx-1.10.2-1.el6.x86_64

###不要用yum卸載帚呼，用rpm -e卸載。

5.service模塊

功能說明：啟動停止服務(wù)

cron模塊

功能說明：管理定時任務(wù)條目信息模塊

創(chuàng)建定時任務(wù)：

ansible oldboy -m cron -a "name='sync time' minute=00 hour=00 job='/usr/sbin/ntpdate time.nist.gov >/dev/null 2>&1'"

結(jié)果：

#Ansible: sync time

00 00 * * * /usr/sbin/ntpdate time.nist.gov >/dev/null 2>&1

添加如下定時任務(wù)：

05 03 * * * /bin/sh /server/scripts/backup.sh /server/scripts/list >/dev/null 2>&1

命令如下：

ansible oldboy -m cron -a "name='backup data' minute=05 hour=03 job='/bin/sh /server/scripts/backup.sh /server/scripts/list >/dev/null 2>&1'"

結(jié)果：

#Ansible: backup data

05 03 * * * /bin/sh /server/scripts/backup.sh /server/scripts/list >/dev/null 2>&1

刪除定時任務(wù)：

ansible oldboy -m cron -a "name='backup data' state=absent"
