  ansible模块有很多，具体模块的使用方法可以使用 ansible-doc 命令可以详细的查看，最下面给的还有实例，很是方便。

下面我自己罗列的一写常用的模块使用方法，便于以后查找使用。

copy 复制本地文件到远程(类似scp命令)

1 2 3 4 5 6 7

- copy: src=/srv/myfiles/foo.conf dest=/etc/foo.conf owner=foo group=foo mode=0644 - copy: src=/srv/myfiles/foo.conf dest=/etc/foo.conf owner=foo group=foo mode="u=rw,g=r,o=r" - copy: src=/srv/myfiles/foo.conf dest=/etc/foo.conf owner=foo group=foo mode="u+rw,g-wx,o-rwx" - copy: src=/mine/ntp.conf dest=/etc/ntp.conf owner=root group=root mode=644 backup=yes - copy: src=/mine/sudoers dest=/etc/sudoers validate='visudo -cf %s' ansible test -m copy -a 'src=/tmp/test.txt dest=/tmp/t.txt'  # 将本地'/tmp/test.txt'文件复制到test主机并重命名'/tmp/t.txt' ansible test -m copy -a 'src=/tmp/dir dest=/tmp/'   # 将本地'/tmp/dir'目录复制到test主机'/tmp/'目录下

fetch  远程文件copy到本地

1 2 3 4

- fetch: src=/tmp/somefile dest=/tmp/fetched - fetch: src=/tmp/somefile dest=/tmp/prefix-{{ ansible_hostname }} flat=yes - fetch: src=/tmp/uniquefile dest=/tmp/special/ flat=yes - fetch: src=/tmp/uniquefile dest=special/prefix-{{ ansible_hostname }} flat=yes

replace 替换(类似sed命令)

1	ansible test -m replace -a "dest=/etc/hosts regexp='Old' replace='New' backeup=yes"

authorized_key 添加互信

1 2 3 4 5 6 7 8

- authorized_key: user=test state=present key=\"{{ lookup('file', '/home/test/.ssh/id_rsa.pub') }}\"  # 添加test互信 - authorized_key: user=test                                                   # 远程用户             state=present  # 新建，absent删除             key=\"{{ lookup('file', '/home/test/.ssh/id_rsa.pub') }}\" # 本地公钥             path='/data/test/.ssh/authorized_keys'              # 额外指定远程用户权限文件,默认是远程用户的家目录下/$HOMEDIR/.ssh/authorized_keys             manage_dir=no                               # 根据path指定的路径创建远程用户权限文件authorized_keys ansible all -m authorized_key -a "user=root state=present key=\"{{ lookup('file', '/root/.ssh/id_rsa.pub') }}\"" -k    # 将本地root的公钥导入到远程用户root的authorized_keys里 ansible all -m authorized_key -a "user=root state=present key=\"{{ lookup('file', '/home/test/.ssh/id_rsa.pub') }}\"" -k # 将本地test的公钥导入到远程用户root的authorized_keys里

synchronize 同步(类似rsync命令)

1 2 3 4 5 6 7 8 9 10 11 12 13

src=/some/relative/path dest=/some/absolute/path dest_port=22   # 指定远程端口 delete=yes     # 使两边的内容一样（即以推送方为主） compress=yes   # 开启压缩，默认为开启 --exclude=.git # 忽略同步.git结尾的文件 recursive=yes  # 递归 checksum=yes   # 默认 no archive=no    links=yes times=no - synchronize: src=/tmp/helloworld dest=/var/www/helloword rsync_opts=--no-motd,--exclude=.gi dest_port=22 - synchronize: src=/tmp/dir dest=/tmp/ dest_port=2020 delete=yes recursive=yes rsync_opts=--no-motd,--exclude=.log # 通过2020端口拷贝目录/tmp/dir到远程/tmp/下面,保持和源目录结构一致,忽略 .log文件 - synchronize: src=/tmp/dir dest=/tmp/ dest_port=2020 delete=yes recursive=yes rsync_opts=--exclude-from=/tmp/ex   # 通过2020端口拷贝目录/tmp/dir到远程/tmp/下面，保持和源目录结构一致并且过滤/tmp/ex文件里的内容

lineinfile 行替换

1 2 3 4 5 6 7

- lineinfile: dest=/etc/selinux/config regexp=^SELINUX= line=SELINUX=enforcing      # 将以“SELINUX”开头的行换成 “SELINUX=enforcing” - lineinfile: dest=/etc/sudoers state=absent regexp="^%wheel"                       # 将以 %wheel 开头的行删除 - lineinfile: dest=/etc/hosts regexp='^127\.0\.0\.1' line='127.0.0.1 localhost' owner=root group=root mode=0644 - lineinfile: dest=/etc/httpd/conf/httpd.conf regexp="^Listen " insertafter="^#Listen " line="Listen 8080" # 将以 #Listen 开头行的下面的 以Listen开头的行换成  Listen 8080 - lineinfile: dest=/etc/httpd/conf/httpd.conf insertafter="^#Listen " line="Listen 8080"            # 在 #Listen 开头行的下面的 添加 Listen 8080 新行 - lineinfile: dest=/etc/httpd/conf/httpd.conf regexp="^Listen " insertbefore="^#Listen " line="Listen 8080" # 将以 #Listen 开头行的上面的 以Listen开头的行换成  Listen 8080 - lineinfile: dest=/tmp/testfile line="192.168.1.99 foo.lab.net foo"  # 添加一个新行

unarchive 解压缩

1 2 3 4 5 6 7 8 9 10

src   copy  yes|no  # yes:默认，压缩包在本地,src=本地压缩包路径，dest=解压到远程路径；no远程主机已存在压缩包，src=远程压缩包路径，dest=解压到远程路径   creates  # 创建文件目录，当文件存在就不执行   dest   group   mode   owner   - unarchive: src=foo.tgz dest=/var/lib/foo - unarchive: src=/tmp/foo.zip dest=/usr/local/bin copy=no - unarchive: src=/tmp/test.tar.gz dest=/opt/tmp/ creates=/opt/tmp/ copy=no

mysql_relication  mysql的主从复制

1 2 3

- mysql_replication: mode=stopslave - mysql_replication: mode=changemaster master_host=192.168.1.1 master_log_file=mysql-bin.000009 master_log_pos=4578 - mysql_replication: mode=getslave login_host=ansible.example.com login_port=3308

mysql_user mysql的用户授权

1 2 3 4 5

- mysql_user: name=bob password=12345 priv=*.*:ALL state=present         # 所以权限 - mysql_user: name=bob password=12345 priv=*.*:ALL,GRANT state=present   # 所以权限包括 with grant option - mysql_user: name=bob append_privs=true priv=*.*:REQUIRESSL state=present - mysql_user: login_user=root login_password=123456 name=sally state=absent # 删除用户 - mysql_user: name=replication password=12345 priv=*.*:"REPLICATION CLIENT" state=present  # 创建从用户
