unarchive and archive

yum

cron

#备份数据库脚本
[root@centos8 ~]#cat mysql_backup.sh 
mysqldump -A -F --single-transaction --master-data=2 -q -uroot |gzip > /data/mysql_date +%F_%T.sql.gz
#创建任务
ansible 10.0.0.8 -m cron -a ‘hour=2 minute=30 weekday=1-5 name="backup mysql" job=/root/mysql_backup.sh‘
ansible websrvs   -m cron -a "minute=*/5 job=‘/usr/sbin/ntpdate 172.20.0.1 &>/dev/null‘ name=Synctime"
#禁用计划任务
ansible websrvs   -m cron -a "minute=*/5 job=‘/usr/sbin/ntpdate 172.20.0.1 &>/dev/null‘ name=Synctime disabled=yes"
#启用计划任务
ansible websrvs   -m cron -a "minute=*/5 job=‘/usr/sbin/ntpdate 172.20.0.1 &>/dev/null‘ name=Synctime disabled=no"
#删除任务
ansible websrvs -m cron -a "name=‘backup mysql‘ state=absent"
ansible websrvs -m cron -a ‘state=absent name=Synctime‘

service

ansible all -m service -a ‘name=httpd state=started enabled=yes‘
ansible all -m service -a ‘name=httpd state=stopped‘
ansible all -m service -a ‘name=httpd state=reloaded’
ansible all -m shell -a "sed -i ‘s/^Listen 80/Listen 8080/‘ /etc/httpd/conf/httpd.conf"
ansible all -m service -a ‘name=httpd state=restarted‘ 

user and group

#创建用户
ansible all -m user -a ‘name=user1 comment=“test user” uid=2048 home=/app/user1 group=root‘
ansible all -m user -a ‘name=nginx comment=nginx uid=88 group=nginx groups="root,daemon" shell=/sbin/nologin system=yes create_home=no  home=/data/nginx non_unique=yes‘
#删除用户及家目录等数据
ansible all -m user -a ‘name=nginx state=absent remove=yes‘
#创建组
ansible websrvs -m group  -a ‘name=nginx gid=88 system=yes‘
#删除组
ansible websrvs -m group  -a ‘name=nginx state=absent‘

lineinfile and replace

lineinfile

ansible在使用sed进行替换时，经常会遇到需要转义的问题，而且ansible在遇到特殊符号进行替换时，存在问题，无法正常进行替换 。其实在ansible自身提供了两个模块：lineinfile模块和replace模块，可以方便的进行替换功能：相当于sed，可以修改文件内容

ansible all -m   lineinfile -a "path=/etc/selinux/config regexp=‘^SELINUX=‘ line=‘SELINUX=enforcing‘"
ansible all -m lineinfile  -a ‘dest=/etc/fstab state=absent regexp="^#"‘

replace

该模块有点类似于sed命令，主要也是基于正则进行匹配和替换

ansible all -m replace -a "path=/etc/fstab regexp=‘^(UUID.*)‘ replace=‘#\1‘"  
ansible all -m replace -a "path=/etc/fstab regexp=‘^#(.*)‘ replace=‘\1‘"

setup

setup 模块来收集主机的系统信息，这些 facts 信息可以直接以变量的形式使用，但是如果主机较多，会影响执行速度，可以使用gather_facts: no

ansible all -m setup
ansible all -m setup -a "filter=ansible_os_family
ansible all -m setup -a "filter=ansible_hostname"
