1. 安装Jenkins

最近不知道为啥，根据官网Linux安装Jenkins的时候下不来安装包，提示连接超时。尝试多次无果后决定在window上安装

curl -fsSL https://pkg.jenkins.io/debian-stable/jenkins.io.key | sudo tee /usr/share/keyrings/jenkins-keyring.asc > /dev/null
curl: (7) Failed to connect to pkg.jenkins.io port 443: Connection timed out

1.1.下载了一个jenkins.msi

安装步骤 Windows

安装到这步的时候，由于公司电脑权限问题我无法打开“Local Security Policy” 导致无法继续安装。

1.2. 下载war包安装

大家如果装的是java8, 建议可以下载老一点的版本，比如2.2xx, 最新版用的是java11，不兼容。

下载地址：jenkins.war

安装步骤：WAR files

贴上内容：

The Jenkins Web application ARchive (WAR) file can be started from the command line like this:

Download the latest Jenkins WAR file to an appropriate directory on your machine
Open up a terminal/command prompt window to the download directory
Run the command java -jar jenkins.war
Browse to http://localhost:8080 and wait until the Unlock Jenkins page appears
Continue on with the Post-installation setup wizard below

Notes:

This process does not automatically install any specific plugins. They need to installed separately via the Manage Jenkins > Manage Plugins page in Jenkins.
You can change the port by specifying the --httpPort option when you run the java -jar jenkins.war command. For example, to make Jenkins accessible through port 9090, then run Jenkins using the command:
java -jar jenkins.war --httpPort=9090

有时候因为公司代理可能没法安装插件：可以通过Manage Jenkins ->Plugin Manager->Advanced->HTTP Proxy Configuration 配置好代理就可以了。

配置job的时候可以使用这个方式模拟sleep

echo "---start---"
ping 127.0.0.1 -n 5 -w 1000 > nul
echo "---end---"

好啦，Jenkins安装成功啦。

2.在ruby环境中调用Jenkins

2.1连接超时

2.6.5 :005 >  client
 => #<JenkinsApi::Client:0x562208267200 @ssl=false, @log_location=#<IO:<STDOUT>>, @log_level=1, @crumbs_enabled=nil, @follow_redirects=nil, @jenkins_path="", @timeout=120>, @http_open_timeout=10>, @http_read_timeout=120>
2.6.5 :004 > client.api_get_request("")
Traceback (most recent call last):
        1: from (irb):4
Net::OpenTimeout (execution expired)

使用下面命令测一下正常

traceroute 10.x.x.x -p 8080

后来发现设置代理后可以正常访问

http_proxy=http://代理IP:8080 rails c

2.2 调用接口时总是提醒“ForbiddenWithCrumb: Access denied”

I, [2022-11-28T02:33:38.752464 #22057]  INFO -- : Crumb expired.  Refetching from the server.
I, [2022-11-28T02:33:39.375018 #22057]  INFO -- : Retrying: 3 out of 3 times...
E, [2022-11-28T02:33:39.375166 #22057] ERROR -- : JenkinsApi::Exceptions::ForbiddenWithCrumb: Access denied. Please ensure that Jenkins is set up to allow access to this operation. A crumb was used in attempt to access operation. Access denied. Please ensure that Jenkins is set up to allow access to this operation.

通过创建一个token, 然后替换掉密码就可以啦。
