1. ansible学习总结： 基础模块

copy模块：
#传输文件到目标机
ansible -i /kingdee/ansible/host all -m copy -a 'src=/tmp/aaaa.tgz dest=/tmp/aaaa.tgz'

cron模块：

ansible -i /kingdee/ansible/hosts all -m cron -a " job='/usr/bin/ntpdate 88.888.88.88 &>/dev/null' name="Sycntime" state=absent"

yum模块，只支持centos:
#安装
ansible -i /kingdee/ansible/hosts all -m yum -a "name=net-tools state=latest" -become
ansible -i /kingdee/ansible/hosts all -m yum -a "name=httpd" -become

ansible -i /kingdee/ansible/hosts all -m yum -a "name=httpd state=absent" -become
#指定下载源,安装多个组件,包括版本
ansible -i /kingdee/ansible/hosts all -m yum -a "name=net-tools,nginx,mysql,git-1.8.3.1-23.el7_8.x86_64 state=latest enablerepo=local" -become

service模块：

group模块：
#创建组：

user模块：
#创建用户create_home是否创建home目录，home路径
ansible -i /kingdee/ansible/hosts all -m user -a "name=testadmin comment='test_uer' uid=1001 groups=1001 shell=/sbin/nologin system=yes create_home=yes home=/home/test_user" -become

#删除用户，remove=yes删除用户home目录
ansible -i /kingdee/ansible/hosts all -m user -a "name=testadmin state=absent remove=yes" -become

lineinfile模块：操作都是行，注意不是特定字段
#创建testfile.txt文件行
ansible -i /kingdee/ansible/hosts all -m shell -a "echo 'aaaaaa123asdf' > /kingdee/testfile.txt" -become
#替换testfile.txt中的内容aaaaaa
ansible -i /kingdee/ansible/hosts all -m lineinfile -a "path=/kingdee/testfile.txt regexp='aaaaaaa' line='bbbbbb'" -become
#删除已#号开头的行
ansible -i /kingdee/ansible/hosts all -m lineinfile -a "path=/kingdee/testfile.txt regexp='^#' state=absent'" -become


replace模块：替换文件夹中的内容
ansible -i /kingdee/ansible/hosts all -m replace -a "path=/kingdee/testfile.txt regexp='bbbbbb' replace='asdf123123134523452'" -become

setup模块：手机远程主机信息

ansible_all_ipv4_addresses：仅显示ipv4的信息。
ansible_devices：仅显示磁盘设备信息。
ansible_distribution：显示是什么系统，例：centos,suse等。
ansible_distribution_major_version：显示是系统主版本。
ansible_distribution_version：仅显示系统版本。
ansible_machine：显示系统类型，例：32位，还是64位。
ansible_eth0：仅显示eth0的信息。
ansible_hostname：仅显示主机名。
ansible_kernel：仅显示内核版本。
ansible_lvm：显示lvm相关信息。
ansible_memtotal_mb：显示系统总内存。
ansible_memfree_mb：显示可用系统内存。
ansible_memory_mb：详细显示内存情况。
ansible_swaptotal_mb：显示总的swap内存。
ansible_swapfree_mb：显示swap内存的可用内存。
ansible_mounts：显示系统磁盘挂载情况。
ansible_processor：显示cpu个数(具体显示每个cpu的型号)。
ansible_processor_vcpus：显示cpu个数(只显示总的个数)。

#查找IP地址，使用filter进行过滤，可以采用通配符查找
ansible -i /kingdee/ansible/hosts all -m setup -a "filter=*ipv4_addresses*"
#查找版本
ansible -i /kingdee/ansible/hosts all -m setup -a "filter=ansible_distribution_major_version"
#为减少每次执行ansile都需要收集setup,效率比较低，可以增加gather_facts:no来禁止手机facts
