• 服务端安装ansible

[root@k8s-mater]yum install https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm[root@k8s-mater]yum install ansible -y[root@k8s-master ansible]# ansible --helpUsage: ansible  [options]Options:  -a MODULE_ARGS, --args=MODULE_ARGS                        module arguments  -k, --ask-pass        ask for SSH password  --ask-su-pass         ask for su password  -K, --ask-sudo-pass   ask for sudo password  --ask-vault-pass      ask for vault password  -B SECONDS, --background=SECONDS                        run asynchronously, failing after X seconds                        (default=N/A)  -C, --check           don't make any changes; instead, try to predict some                        of the changes that may occur  -c CONNECTION, --connection=CONNECTION                        connection type to use (default=smart)  -f FORKS, --forks=FORKS                        specify number of parallel processes to use                        (default=5)  -h, --help            show this help message and exit  -i INVENTORY, --inventory-file=INVENTORY                        specify inventory host file                        (default=/etc/ansible/hosts)  -l SUBSET, --limit=SUBSET                        further limit selected hosts to an additional pattern  --list-hosts          outputs a list of matching hosts; does not execute                        anything else  -m MODULE_NAME, --module-name=MODULE_NAME                        module name to execute (default=command)  -M MODULE_PATH, --module-path=MODULE_PATH                        specify path(s) to module library                        (default=/usr/share/ansible/)  -o, --one-line        condense output  -P POLL_INTERVAL, --poll=POLL_INTERVAL                        set the poll interval if using -B (default=15)  --private-key=PRIVATE_KEY_FILE                        use this file to authenticate the connection  -S, --su              run operations with su  -R SU_USER, --su-user=SU_USER                        run operations with su as this user (default=root)  -s, --sudo            run operations with sudo (nopasswd)  -U SUDO_USER, --sudo-user=SUDO_USER                        desired sudo user (default=root)  -T TIMEOUT, --timeout=TIMEOUT                        override the SSH timeout in seconds (default=10)  -t TREE, --tree=TREE  log output to this directory  -u REMOTE_USER, --user=REMOTE_USER                        connect as this user (default=root)  --vault-password-file=VAULT_PASSWORD_FILE                        vault password file  -v, --verbose         verbose mode (-vvv for more, -vvvv to enable                        connection debugging)  --version             show program's version number and exit

• 配置hosts,便于后续操控远程主机

cd /etc/ansiblevim hosts## db-[99:101]-node.example.com192.168.189.89

• 编辑/etc/ansible/ansible.cfg

inventory      = /etc/ansible/hosts    #将注释#去掉

• 测试命令

[root@k8s-master ansible]# ansible localhost -m pinglocalhost | SUCCESS => {    "changed": false,    "ping": "pong"}[root@k8s-master ansible]# ansible localhost -m command -a "df -h"localhost | CHANGED | rc=0 >>文件系统                 容量  已用  可用 已用% 挂载点/dev/mapper/centos-root   17G  5.5G   12G   33% /devtmpfs                 475M     0  475M    0% /devtmpfs                    487M  124K  487M    1% /dev/shmtmpfs                    487M   14M  473M    3% /runtmpfs                    487M     0  487M    0% /sys/fs/cgroup/dev/sda1               1014M  133M  882M   14% /boottmpfs                     98M     0   98M    0% /run/user/0
