前言
前两天发布了完整的 linux服务器上Docker中安装jenkins
在实际的开发中，可能我们并不能直接开放8081端口，常常是通过nginx方向代理来实现的，这里我们来配置一下。
linux环境下docker中搭建 jenkins 及自定义访问路径，nginx反向代理
- 前言
- 1 linux服务器上Docker中安装jenkins
- 2 删除原来的容器
- 3 创建挂载目录
- 问题
- 4 nginx配置
- 完成
1 linux服务器上Docker中安装jenkins
如果你还没有安装 可以参考我这篇文章 linux服务器上Docker中安装jenkins
看到目录： 创建一个jenkins目录 就可以回来继续看如何自定义访问路径和nginx反向代理了。
2 删除原来的容器
如果原来有 则需要删除，没有则不需要删除
docker ps -a
docker rm -f 容器id
g6grfnalpZ:/data/jenkins_home# docker ps

grfnalpZ:/data/jenkins_home# docker rm -f 0f9ea3076687
0f9ea3076687
3 创建挂载目录
mkdir /data/jenkins_home
chown -R 1000:1000 /data/jenkins_home
如果原来没有启动容器挂载过
docker run -d --name jenkins -p 8899:8080 --restart=always -e TZ=“Asia/Shanghai” -e JENKINS_OPTS=“–prefix=/jenkins” -e JENKINS_ARGS=“–prefix=/jenkins” -v /www/jenkins:/var/jenkins_home -v /data/jenkins_home:/var/jenkins_home jenkins/jenkins:lts;
如果已经挂载过了
docker run -d --name jenkins -p 8899:8080 --restart=always -e TZ=“Asia/Shanghai” -e JENKINS_OPTS=“–prefix=/jenkins” -e JENKINS_ARGS=“–prefix=/jenkins” jenkins/jenkins:lts;
没有挂载过的主要就是去除了两个挂载的参数
-v /www/jenkins:/var/jenkins_home
-v /data/jenkins_home:/var/jenkins_home
问题
这里如果挂载过了，会出现这个问题
8g6grfnalpZ:/data# docker run -d --name jxj_jenkins -p 8899:8080 --restart=always -e TZ="Asia/Shanghai" -e JENKINS_OPTS="--prefix=/jenkins" -e JENKINS_ARGS="--prefix=/jenkins" -v /data/jenkins_home:/var/jenkins_home -v /www/jenkins:/var/jenkins_home jenkins/jenkins:lts;
docker: Error response from daemon: Duplicate mount point: /var/jenkins_home.
See 'docker run --help'.
Duplicate mount point 重复挂载点的意思。
参数解析：
-d 后台运行容器，并返回容器ID；
--name 为容器起一个容易区分且容易书写的名字
-p 映射宿主机端口到容器端口，宿主机端口：容器端口
--restart=always 机器重启时自动启动容器
-e 设定一些必须的环境变量。
-e TZ="Asia/Shanghai" 设定时区为上海，强烈建议国内设定，否则容器内打印的所有日志时间都会差8小时。
-e JENKINS_OPTS="--prefix=/jenkins" -e JENKINS_ARGS="--prefix=/jenkins" 重点！！！设定jenkins访问的路径，非必选，如果是直接根目录或ip地址访问，则不需要添加，如果是想nginx反向代理且不在根目录下，则必须，否则只配置nginx会报静态文件404错误，此处名字应与文件夹名称一致。
-v 挂载宿主机文件到容器。本例两个分别为：
-v /etc/localtime:/etc/localtime:ro 挂载宿主机时间，保持容器时间正确。
-v /data/jenkins_home:/var/jenkins_home 绑定挂载文件
4 nginx配置
前提是已经安装好了nginx，如果没有安装，这里可能需要暂停一下安装好再过来。
cd /
find -name nginx.conf
vim nginx.conf路径
添加配置
location ~ (^/jenkins).* {
proxy_pass http://127.0.0.1:8899;
#proxy_set_header Host $host:$server_port;
}
完整nginx.conf配置
#user nobody;
worker_processes 1;
#error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;
#pid logs/nginx.pid;

index index.html index.htm;
}
location ~ (^/jenkins).* {
proxy_pass http://127.0.0.1:8899;
#proxy_set_header Host $host:$server_port;
}
#error_page 404 /404.html;
# redirect server error pages to the static page /50x.html
#
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
# proxy the PHP scripts to Apache listening on 127.0.0.1:80
#
#location ~ \.php$ {
# proxy_pass http://127.0.0.1;
#}
# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
#

# fastcgi_index index.php;
# fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name;
# include fastcgi_params;
#}
# deny access to .htaccess files, if Apache's document root
# concurs with nginx's one
#
#location ~ /\.ht {
# deny all;
#}
}
# another virtual host using mix of IP-, name-, and port-based configuration
#
#server {
# listen 8000;
# listen somename:8080;
# server_name somename alias another.alias;
# location / {
# root html;
# index index.html index.htm;
# }
#}
# HTTPS server

#server {
# listen 443 ssl;
# server_name localhost;
# ssl_certificate cert.pem;

# ssl_ciphers HIGH:!aNULL:!MD5;
# ssl_prefer_server_ciphers on;
# location / {

完成
