centos 7中安装jenkins

1.安装java11

[root@localhost ~]# yum install -y java-11-openjdk-devel
[root@localhost ~]# java --version
openjdk 11.0.23 2024-04-16 LTS
OpenJDK Runtime Environment (Red_Hat-11.0.23.0.9-2.el7_9) (build 11.0.23+9-LTS)
OpenJDK 64-Bit Server VM (Red_Hat-11.0.23.0.9-2.el7_9) (build 11.0.23+9-LTS, mixed mode, sharing)
[root@localhost ~]# which java
/usr/bin/java

2.安装jenkins

[root@localhost ~]# wget https://mirrors.tuna.tsinghua.edu.cn/jenkins/redhat-stable/jenkins-2.516.2-1.1.noarch.rpm
[root@localhost ~]# rpm -ivh jenkins-2.516.2-1.1.noarch.rpm 
warning: jenkins-2.516.2-1.1.noarch.rpm: Header V4 RSA/SHA512 Signature, key ID ef5975ca: NOKEY

   1:jenkins-2.516.2-1.1              ################################# [100%]
[root@localhost ~]# rpm -ql jenkins 
/usr/bin/jenkins
/usr/lib/systemd/system/jenkins.service
/usr/lib/tmpfiles.d/jenkins.conf
/usr/share/java/jenkins.war
/usr/share/jenkins/migrate
/var/cache/jenkins
/var/lib/jenkins

3.修改jenkins配置

[root@localhost ~]# vi /usr/lib/systemd/system/jenkins.service
  • 把user和Group改成root, 也可以修改端口（默认是8080）
# Unix account that runs the Jenkins daemon
# Be careful when you change this, as you need to update the permissions of
# $JENKINS_HOME, $JENKINS_LOG, and (if you have already run Jenkins)
# $JENKINS_WEBROOT.
#User=jenkins
#Group=jenkins
User=root
Group=root


# Directory where Jenkins stores its configuration and workspaces
Environment="JENKINS_HOME=/var/lib/jenkins"
WorkingDirectory=/var/lib/jenkins

# Location of the Jenkins WAR
#Environment="JENKINS_WAR=/usr/share/java/jenkins.war"

# Location of the exploded WAR
Environment="JENKINS_WEBROOT=%C/jenkins/war"

# Location of the Jenkins log. By default, systemd-journald(8) is used.
#Environment="JENKINS_LOG=%L/jenkins/jenkins.log"

# The Java home directory. When left empty, JENKINS_JAVA_CMD and PATH are consulted.
#Environment="JAVA_HOME=/usr/lib/jvm/java-17-openjdk-amd64"

# The Java executable. When left empty, JAVA_HOME and PATH are consulted.
#Environment="JENKINS_JAVA_CMD=/etc/alternatives/java"

# Arguments for the Jenkins JVM
Environment="JAVA_OPTS=-Djava.awt.headless=true"

# Unix Domain Socket to listen on for local HTTP requests. Default is disabled.
#Environment="JENKINS_UNIX_DOMAIN_PATH=/run/jenkins/jenkins.socket"

# IP address to listen on for HTTP requests.
# The default is to listen on all interfaces (0.0.0.0).
#Environment="JENKINS_LISTEN_ADDRESS="

# Port to listen on for HTTP requests. Set to -1 to disable.
# To be able to listen on privileged ports (port numbers less than 1024),
# add the CAP_NET_BIND_SERVICE capability to the AmbientCapabilities
# directive below.
Environment="JENKINS_PORT=8080"

# 重新加载配置
[root@localhost ~]# systemctl daemon-reload

4.安装失败需卸载

[root@localhost ~]# rpm -e jenkins
[root@localhost ~]# rpm -ql jenkins
[root@localhost ~]# find / -iname jenkins | xargs -n 1000 rm -rf

5.启动jenkins

[root@localhost ~]# systemctl start jenkins.service
Redirecting to /bin/systemctl start jenkins.service
[root@localhost ~]# systemctl status jenkins.service 
● jenkins.service - Jenkins Continuous Integration Server
   Loaded: loaded (/usr/lib/systemd/system/jenkins.service; disabled; vendor preset: disabled)

6. 操作jenkins

[root@localhost ~]# cat /var/lib/jenkins/secrets/initialAdminPassword
16c7038972324a8992d96f8c78686739

表示jenkins已经启动成功，这时可以去外面机器访问这个jenkins

7. 修改管理员密码

[root@localhost ~]# cd /var/lib/jenkins
[root@localhost jenkins]# ls
