安装前的准备准备

如果本机是首次使用docker-compose环境部署，需要在在/deploy/sorts创建以下脚本并执行 vi pre_install.sh

vi pre_install.sh
#!/bin/bash
###关闭selinux
sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config
setenforce 0
yum install -y yum-utils device-mapper-persistent-data lvm2
yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
yum makecache fast
yum -y install docker-ce
###配置拉取国内镜像仓库
tee /etc/docker/daemon.json <<-'EOF'
{
"registry-mirrors": [
 "https://5sr5uink.mirror.aliyuncs.com",
 "https://docker.mirrors.ustc.edu.cn",
 "https://hub-mirror.c.163.com",
 "https://mirror.baidubce.com"
  ],
 "insecure-registries": ["harbor.xxx.com"]
}
EOF
###启动docker
systemctl start docker
systemctl enable docker
### 下载docker-compose
curl -L "https://get.daocloud.io/docker/compose/releases/download/1.29.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/bin/docker-compose
chmod +x /usr/bin/docker-compose
docker-compose -version

sh pre_install.sh

创建nexus目录及相关子目录

mkdir /deploy/sorts/nexus3
cd /deploy/sorts/nexus3
mkdir data

创建yml编排文件

vi docker-compose.yml
version: '3.7'
services:
  nexus:
    image: harbor.xxx.com/xxx/nexus3
    restart: always
    container_name: nexus3
    ports:
    - "8081:8081"
    volumes:
    - ./data:/nexus-data
    environment:
    - TZ=Asia/Shanghai

创建启动和停止脚本

vi up.sh
#!/bin/bash

set -e

tm=`date +%Y%m%d-%H%M%S`
echo "====================================================="
echo "Starting nexus3."
echo "Starting <${tm}>."
echo "====================================================="
echo "Please ensure the config files right."
echo "====================================================="

docker-compose  -p nexus3 up -d

vi down.sh
#!/bin/bash

set -e

tm=`date +%Y%m%d-%H%M%S`
echo "====================================================="
echo "Stopping nexus3."
echo "Stopping <${tm}>."
echo "====================================================="
echo "Please ensure the config files right."
echo "====================================================="

docker-compose -p nexus3 down

启动

sh ups.sh
[root@localhost-203-root-all nexus3]# docker-compose ps
 Name               Command               State                    Ports                  
------------------------------------------------------------------------------------------
nexus3   sh -c ${SONATYPE_DIR}/star ...   Up      0.0.0.0:8081->8081/tcp,:::8081->8081/tcp

配置阿里云缓存仓库

浏览器访问nexus所在节点IP+8081 设置--Repository--Create Repository----Maven2(proxy) 在Remote Storage里面填上阿里云私库地址http://maven.aliyun.com/nexus/content/groups/public/
