[n /Y ] y Key for minion test230 accepted. 附上【salt-key】常用命令 Actions: -l ARG, --list=ARG List the public keys. The args "pre" , "un" , and "unaccepted" will list unaccepted /unsigned keys. "acc" or "accepted" will list accepted /signed keys. "rej" or "rejected" will list rejected keys. Finally, "all" will list all keys. -L, --list-all List all public keys. (Deprecated: use "--list all" ) -a ACCEPT, --accept=ACCEPT Accept the specified public key (use --include-all to match rejected keys in addition to pending keys). Globs are supported. -A, --accept-all Accept all pending keys -r REJECT, --reject=REJECT Reject the specified public key (use --include-all to match accepted keys in addition to pending keys). Globs are supported. -R, --reject-all Reject all pending keys --include-all Include non-pending keys when accepting /rejecting -p PRINT, --print=PRINT Print the specified public key -P, --print-all Print all public keys -d DELETE, --delete=DELETE Delete the specified key. Globs are supported. -D, --delete-all Delete all keys -f FINGER, --finger=FINGER Print the specified key's fingerprint -F, --finger-all Print all keys' fingerprints 3. 【salt-minion】 安装: [root@test230 download] # yum install salt-minion 配置master和自己的 id : [root@test230 download] # cat /etc/salt/minion |grep ^[^#] master: 10.0.200.21 id : test230 启动服务: [root@test230 download] # service salt-minion start Starting salt-minion daemon: [ OK ] 注意:master的端口需要开放才能访问。 [root@test230 download] # service salt-minion restart Stopping salt-minion daemon: [FAILED] Starting salt-minion daemon: [ OK ] 等待master接受minion的key master已接受 4. 测试 [root@server200-21 ~] # salt '*' test.ping test230: True 接下来,测试安装一个服务: 配置master: [root@server200-21 ~] # cat /etc/salt/master |grep -v ^$|grep -v ^# file_roots: base: - /srv/salt [root@server200-21 ~] # mkdir /srv/salt/ [root@server200-21 ~] # cd /srv/salt/ [root@server200-21 salt] # ls servers.sls top .sls [root@server200-21 salt] # cat top.sls base: '*' : - servers [root@server200-21 salt] # cat servers.sls dnsmasq: pkg: - installed 执行: [root@server200-21 salt] # salt '*' state.highstate test230: ---------- ID: dnsmasq Function: pkg.installed Result: True Comment: Package dnsmasq is already installed.
