CI环境搭建——Nexus

Nexus现在为Nexus Repository Manager OSS 3.x。

安装

这里想要把Nexus安装在/opt目录下: cd /opt

下载安装包：wget https://sonatype-download.global.ssl.fastly.net/nexus/3/nexus-3.4.0-02-unix.tar.gz

1）解压（我这边是解压到/opt中）

sudo tar -zxvf nexus-3.4.0-02-unix.tar.gz

2）创建链接

sudo ln -s nexus-3.4.0-02 nexus

3）创建nexus用户

sudo useradd nexus

4）授权

sudo chown -R nexus:nexus /opt/nexus
sudo chown -R nexus:nexus /opt/sonatype-work/

5）修改运行用户，这边直接用nexus用户。

sudo vi /opt/nexus/bin/nexus.rc

# 修改一下内容
run_as_user="nexus"

6）修改端口号：修改文件/opt/nexus/etc/nexus-default.properties中的application-port为你想要的端口号。

7）启动服务：在/opt/nexus/bin的目录下运行./nexus run &。这一步可以忽略，也就是这一步可以不做。

8）配置数据目录

因为仓库占用存储较大，所以我们在安装的时候得注意存储目录的位置。参考官网上的说明（如下）进行修改：

2.10.4. Configuring the Data Directory

You can use $install-dir/bin/nexus.vmoptions to define a new location for data you want to preserve. In the configuration file change the values of -Dkaraf.data, -Djava.io.tmpdir, and -XX:LogFile to designate an absolute path you prefer to use.

The nexus service will look to add the data directory to the absolute path that you configure. For example, to use the absolute path /opt/sonatype-work/nexus3 change the values as follows:

-Dkaraf.data=/opt/sonatype-work/nexus3
-Djava.io.tmpdir=/opt/sonatype-work/nexus3/tmp
-XX:LogFile=/opt/sonatype-work/nexus3/log/jvm.log

以上代码中的/opt/sonatype-work/可以替换成你的目录

9）注册为服务

vi /etc/systemd/system/nexus.service

添加如下内容：

[Unit]
Description=nexus service
After=network.target

[Service]
Type=forking
ExecStart=/opt/nexus/bin/nexus start
ExecStop=/opt/nexus/bin/nexus stop
User=nexus
Restart=on-abort

[Install]
WantedBy=multi-user.target

10）安装并启动服务

sudo systemctl daemon-reload
sudo systemctl enable nexus.service
sudo systemctl start nexus.service

11）查看服务

sudo systemctl status nexus.service

12）添加防火墙规则

13）配置Nginx代理

配置文件如下：

server {
    listen       *:80;
    server_name  maven.xxxx.io maven.xxxx.com;

    client_max_body_size 1G;

    location / {
        proxy_pass http://xxx.xxx.xxx.xxx:8081/;
        proxy_set_header Host $host;
        proxy_set_header X-Real-Ip $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    }
    error_page 404 /404.html;
        location = /40x.html {
    }
    error_page 500 502 503 504 /50x.html;
        location = /50x.html {
    }
}
