使用Docker安装

基础环境

docker环境
查看docker版本

[root@localhost ~]# docker -v
Docker version 18.06.0-ce, build 0ffa825

新建用户目录，用户挂载容器存储

useradd jenkins-docker

运行docker命令

docker run -p 8081:8080 -p 50001:50000  -v /home/jenkins-docker:/var/jenkins_home hub.c.163.com/library/jenkins:latest

命令中没有使用后台启动为了查看输出的管理员密码

若使用了挂载目录也可以在挂载的目录下查看

访问web界面，输入密码即可

使用原生系统安装

基础环境

CentOS7 1804最小安装

安装基础wget工具yum install -y wget

导入仓库源

wget -O /etc/yum.repos.d/jenkins.repo http://pkg.jenkins.io/redhat-stable/jenkins.repo

下载并导入仓库的key，用于验证仓库安全性

rpm --import http://pkg.jenkins.io/redhat-stable/jenkins.io.key

安装java8

yum -y install java

验证java版本

[root@localhost ~]# java -version
openjdk version "1.8.0_181"
OpenJDK Runtime Environment (build 1.8.0_181-b13)
OpenJDK 64-Bit Server VM (build 25.181-b13, mixed mode)

关闭防火墙

[root@localhost ~]# systemctl stop firewalld

关闭防火墙开机启动

[root@localhost ~]# systemctl disable firewalld
Removed symlink /etc/systemd/system/multi-user.target.wants/firewalld.service.
Removed symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.

关闭强制访问控制安全策略

vi /etc/sysconfig/selinux

# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
#     enforcing - SELinux security policy is enforced.
#     permissive - SELinux prints warnings instead of enforcing.
#     disabled - No SELinux policy is loaded.
SELINUX=enforcing
# SELINUXTYPE= can take one of three two values:
#     targeted - Targeted processes are protected,
#     minimum - Modification of targeted policy. Only selected processes are protected.
#     mls - Multi Level Security protection.
SELINUXTYPE=targeted

SELINUX=enforcing

改成

SELINUX=disabled

reboot使禁用操作生效

查看操作是否生效

[root@localhost ~]# getenforce
Disabled

安装jenkins

直接安装

yum -y install jenkins

安装后会自动添加jenkins，此时可以自定义发布用户

[root@localhost ~]# useradd jenkins
useradd：用户“jenkins”已存在
[root@localhost ~]# useradd deploy

配置

编辑配置文件

[root@localhost ~]# vi /etc/sysconfig/jenkins 

将用户改为新建的用户JENKINS_USER="deploy"，端口号默认为8080

修改log目录和权限

[root@localhost ~]# chown -R deploy:deploy /var/lib/jenkins
[root@localhost ~]# chown -R deploy:deploy /var/log/jenkins
[root@localhost ~]# chown -R deploy:deploy /var/cache/jenkins

启动jenkins

[root@localhost ~]# systemctl start jenkins

查看服务是否启动

[root@localhost ~]# ps -ef | grep jenkins
root       1445   1311  0 19:06 pts/0    00:00:00 grep --color=auto jenkins

或者使用lsof（需要额外安装）

[root@localhost jenkins]# lsof -i:8080
COMMAND  PID   USER   FD   TYPE DEVICE SIZE/OFF NODE NAME
java    1683 deploy  161u  IPv6  24353      0t0  TCP *:webcache (LISTEN)

访问web界面

地址为ip:8080

去提示的目录下查找密码
