遇到的問題：
yum clean all
yum makecache
220的war包無法自動(dòng)部署到另一臺(tái)服務(wù)器
解決方案：1、兩個(gè)服務(wù)器之間需要互通；2、jenkins安裝了：publish over ssh 插件
1、首先我們需要將jenkins服務(wù)器的公鑰放到需要部署的服務(wù)器上，實(shí)現(xiàn)可以免密登陸，
2、到系統(tǒng)管理 --> 系統(tǒng)設(shè)置 --> 向下拉找到? publish over ssh 然后去配置
安裝完插件后，直接在linux機(jī)器上重啟jenkins服務(wù)，而不是勾選空閑時(shí)重啟
# systemctl restart jenkins
重新在瀏覽器上登錄jenkins，并在linux機(jī)器上生成一對(duì)秘鑰
# cd ~/.ssh/
# ls? ? #如果之前有生成過密鑰對(duì)，那可以直接用，不需要再生成
authorized_keys? known_hosts
# ssh-keygen -f ~/.ssh/jenkins? ? #生成密鑰對(duì)
Generating public/private rsa key pair.
Enter passphrase (empty for no passphrase):? ? #直接回車，也可以設(shè)置密碼
Enter same passphrase again:? ? #直接回車
Your identification has been saved in /root/.ssh/jenkins.
Your public key has been saved in /root/.ssh/jenkins.pub.
The key fingerprint is:

系統(tǒng)管理–>系統(tǒng)設(shè)置，找到之前安裝的Publish over SSH插件，Passphrase填寫之前生成秘鑰時(shí)設(shè)置的密碼，沒有則留空，Path to key留空，Key粘貼/root/.ssh/jenkins文件內(nèi)容。
然后新增SSH Servers，填入對(duì)應(yīng)的hostname，這就是PHP代碼要發(fā)布的機(jī)器
接下來還需要把公鑰拷貝到對(duì)應(yīng)的hostname機(jī)器（lzx1）上

#exit? ? ?

Connection to lzx1 closed.
[root@lzx .ssh]#? ? #ssh登錄沒問題
瀏覽器上測(cè)試連接有沒有問題，點(diǎn)擊Test Configuration，如果沒問題，左側(cè)會(huì)顯示Success，如下圖
這就說明我們前面的配置是沒問題的。點(diǎn)擊應(yīng)用，出現(xiàn)“已保存”
如果有多臺(tái)web server ，可以繼續(xù)新增，重復(fù)以上操作，最后點(diǎn)擊保存。
