python3 安裝apinode
# 首先安裝python3 tar zxvf Python-3.5.1.tgz cd Python-3.5.1 . ./configure make make install mv /usr/bin/python /usr/bin/python2 # 若是是軟鏈接,能夠直接刪除 ln -s /usr/local/bin/python3.5 /usr/bin/python vim /usr/bin/yum # 修改Yum,使yum依然有效,yum依靠老版本的python #!/usr/bin/python 修改成#!/usr/bin/python2 # 修改完/usr/bin/yum 依然還有問題,能夠嘗試修改/usr/libexec/urlgrabber-ext-down的文件python擡頭 # 使用Python3直接啓動salt,由於默認環境已經切換的python3, 因此直接啓動便可 systemctl start salt-master systemctl start salt-minion systemctl start salt-api #若是有問題可執行 apt-get install python3-dev
python3 -m pip install salt==2017.7.2
[root@k8s_master ~]# pip install pyopenssl #安裝依賴包 [root@k8s_master ~]# yum install salt-api #安裝api服務 [root@k8s_master ~]# useradd username && echo password | passwd --stdin $username #添加用戶 [root@k8s_master ~]# salt-call --local tls.create_self_signed_cert #生成key,默認目錄/etc/pki/tls/certs [root@k8s_master ~]# vi /etc/salt/master rest_cherrypy: port: 8000 #api端口 debug: True ssl_crt: /etc/pki/tls/certs/localhost.crt ssl_key: /etc/pki/tls/certs/localhost.key external_auth: pam: #採用linux自帶的加密方式 saltapi: #以前添加的用戶名 - .* #主機組 - '@wheel' #所須要調用的模塊(如,cmd.*,file.*),這裏表示全部權限 - '@runner' [root@k8s_master ~]# service salt-api start
[root@k8s_master ~]# service salt-master restart
另外一種配置方法python
# 添加配置文件,能夠把eauth.conf和api.conf合二爲一爲api.conf [root@centos7 ~]# mkdir -p /etc/salt/master.d/ # 這個目錄默認不存在,須要手動建立,在/etc/salt/master主配置文件中有指定,相似include [root@centos7 ~]# vim /etc/salt/master.d/eauth.conf # 處於安全因素,通常只給特定模塊的使用權限,這裏給saltapi用戶全部模塊的使用權限 external_auth: pam: saltapi: - .* - '@wheel' - '@runner' [root@k8s_master ~]# vim /etc/salt/master.d/api.conf rest_cherrypy: port: 8000 #salt-api 監聽端口 ssl_crt: /etc/pki/tls/certs/localhost.crt #ssl認證的證書 ssl_key: /etc/pki/tls/private/localhost_nopass.key

參數解釋:express
client : 模塊,python處理salt-api的主要模塊,‘client interfaces <netapi-clients>’ local : 使用‘LocalClient <salt.client.LocalClient>’ 發送命令給受控主機,等價於saltstack命令行中的'salt'命令 local_async : 和local不一樣之處在於,這個模塊是用於異步操做的,即在master端執行命令後返回的是一個jobid,任務放在後臺運行,經過產看jobid的結果來獲取命令的執行結果。 runner : 使用'RunnerClient<salt.runner.RunnerClient>' 調用salt-master上的runner模塊,等價於saltstack命令行中的'salt-run'命令 runner_async : 異步執行runner模塊 wheel : 使用'WheelClient<salt.wheel.WheelClient>', 調用salt-master上的wheel模塊,wheel模塊沒有在命令行端等價的模塊,但它一般管理主機資源,好比文件狀態,pillar文件,salt配置文件,以及關鍵模塊<salt.wheel.key>功能相似於命令行中的salt-key。 wheel_async : 異步執行wheel模塊 備註:通常狀況下local模塊,須要tgt和arg(數組),kwarg(字典),由於這些值將被髮送到minions並用於執行所請求的函數。而runner和wheel都是直接應用於master,不須要這些參數。 tgt : minions fun : 函數 arg : 參數 expr_form : tgt的匹配規則 'glob' - Bash glob completion - Default 'pcre' - Perl style regular expression 'list' - Python list of hosts 'grain' - Match based on a grain comparison 'grain_pcre' - Grain comparison with a regex 'pillar' - Pillar data comparison 'nodegroup' - Match on nodegroup 'range' - Use a Range server for matching 'compound' - Pass a compound match string
