工作中，從git倉庫拉取代碼有２種方式：交互式和非交互式
什么是交互式?就是拉取需要權限才能訪問的代碼時，需要輸入密碼
免交互式呢？ 是通過密鑰，私鑰的方式，讓服務端信任客戶端，產生信任后，任何一次客戶端向服務端發起的請求時，不需要密碼，而是直接進行讀寫等操作。
在持續集成中，jenkins需要去git代碼倉庫拉取代碼，在這個過程中不方便交互式的輸入代碼，所以采用免交互式會比較方便。
密鑰私鑰的生成和使用:
在客戶機linux機器上 ssh-keygen 一路回車
[root@192 ~]# ssh-keygen Generating public/private rsa key pair. Enter file in which to save the key (/root/.ssh/id_rsa): Enter passphrase (empty for no passphrase): Enter same passphrase again: Your identification has been saved in /root/.ssh/id_rsa. Your public key has been saved in /root/.ssh/id_rsa.pub. The key fingerprint is: SHA256:llzcheb6UtbggaOnU6FTjssrLTIM5CQ5FjsnBq2zo5I root@192.168.1.40 The key's randomart image is: +---[RSA 2048]----+ | . .. | |... . .o. | |.oo o+. | |**o. . o= + | |oO+ S* = + | |o o .= = + . | |.o o o * + | |E + o * . . | |. o o.o . | +----[SHA256]-----+ [root@192 ~]# ls .ssh/ id_rsa id_rsa.pub known_hosts
#通過ssh-copy-id命令將/root/.ssh/id_rsa.pub公鑰copy到192.168.1.30git源碼管理服務器上
[root@192 ~]# ssh-copy-id git@192.168.1.30
/usr/bin/ssh-copy-id: INFO: Source of key(s) to be installed: "/root/.ssh/id_rsa.pub"
/usr/bin/ssh-copy-id: INFO: attempting to log in with the new key(s), to filter out any that are already installed
/usr/bin/ssh-copy-id: INFO: 1 key(s) remain to be installed -- if you are prompted now it is to install the new keys
git@192.168.1.30's password:
Number of key(s) added: 1
Now try logging into the machine, with: "ssh 'git@192.168.1.30'"
and check to make sure that only the key(s) you wanted were added.
到192.168.1.30git源碼管理服務器上，查看id_rsa.pub存放到了哪里
[root@192 ~]# su - git [git@192 ~]$ cat .ssh/authorized_keys ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQDPW1GD64WQr/1WdklohJrS35i3MS7Om2m9vXlDW/ZuvuucYiSzEiI9Thr3ooPBlavLRofh/oS3xzu+jHydm9hY20IV73Kmua3BWw3eMLUT6PXs2fvpGpspx9doVmJZ6B4IGN/4VYoFUPTYpy+WxxcqkxPeMQrZ5mcemzlUkB6GcSmNEI2U0lP4z7h+H0i+JvoVd7CF7FCAiYLxsBxLFdQnJxdfvybaQ+qt6bvShqg8Ijus4rveqFSO7NRamGX4KZmvIdgVQ1uMLT5PYuC2u6F+hLhCLg7XoqzqxGtl+4kIgGedQzxxsHzxa1D7x1Hx7SsTlb9xJKJRVE89P0/KOtnf root@192.168.1.40
將客戶端（jenkins)服務器的私鑰配置到jenkins管理界面里，
git代碼倉庫拉代碼的pipeline腳本產生方法
下圖是上圖步驟3里，點開后的配置
下圖是ssh-keygen產生的私鑰 .ssh/id_rsa
到此，步驟5里，就產生了pipeline腳本，免交互方式讓jenkins服務器拉取git代碼倉庫里的代碼
