通过jenkins发布java项目到目标主机上的详细步骤

通过jenkins发布java项目到目标主机上的详细步骤

发布java项目的步骤：

拉取代码并打包

mvn clean package

备份目标服务器上已有的要发布项目

将包传到目标服务器的webapss目录中

需做免密登录

重启目标服务器的tomcat服务

修改项目的配置

重启目标服务器的tomcat服务

项目要求:

两台主机上分别安装jenkins，tomcat

jenkins主机上操作

#两台主机做免密登录

[root@localhost ~]# ssh-keygen -t rsa

Generating pKIrLCDziPLublic/private rsa key pair.

Enter file in which to save the key (/root/.ssh/id_rsa):

Created directory '/root/.ssh'.

Enter passphrase (empty for no passphrase):

Enter same passphrase again:

Your identification has been saved in /rohttp://ot/.ssh/id_rsa.

Your public key has been saved in /root/.ssh/id_rsa.pub.

The key fingerprint is:

SHA256:0zPiM+3ypvmYPisJbeL8LhA2QApiAVqwF9C+gyASonU root@localhost.localdomain

The key's randomart image is:

+---[RSA 3072]----+

[root@localhost ~]# ssh-copy-id root@192.168.8.131

/usr/bin/ssh-copy-id: INFO: Source of key(s) to be installed: "/root/.ssh/id_rsa.pub"

The authenticity of host '192.168.8.131 (192.168.8.131)' can't be established.

ECDSA key fingerprint is SHA256:WbxvLgdwExwRlMT4gaAC1bVyIovZnAwwX1DX8dv6Rs0.

Are you sure you want to continue connecting (yes/no/[fingerprint])? yes

/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

root@192.168.8.131's password:

Number of key(s) added: 1

Now try logging into the machine, with: "ssh 'root@192.168.8.131'"

and check to make sure that only the key(s) you wanted were added.

#安装软件

[root@localhost ~]# yum -y install git maven
