16.Ubuntu16.04安装Nexus

Ubuntu16.04安装Nexus

1.准备环境

linux16.04版本

安装JDK8

2.下载安装包

官网:https://www.sonatype.com/nexus/repository-oss

下载地址:https://sonatype-download.global.ssl.fastly.net/repository/downloads-prod-group/3/nexus-3.29.2-02-unix.tar.gz(强烈推荐用迅雷)

根据需要自行下载

3.上传到你的linux服务器并进行解压

tar xvzf nexus-3.29.2-02-unix.tar.gz

4.启动Nexus

cd /nexus/nexus-3.29.2-02/bin/
sudo ./nexus run
其他命令:
Usage: ./nexus { console | start | stop | restart | status | dump }
启动nexus：
#./nexus start
关闭nexus：
#./nexus stop

运行成功后，会出现

Started Sonatype Nexus OSS 3.29.2-02

注意:如果遇到

Please define INSTALL4J_JAVA_HOME to point to a suitable JVM.

请重新配置下jdk路径

vi /nexus/nexus-3.29.2-02/bin/nexus

5.访问nexus UI界面

6.配置为Linux Service

编辑bin/nexus.rc：

vi /nexus/nexus-3.29.2-02/bin/nexus.rc

#run_as_user=""
run_as_user="root"

注意:红色部分是用什么用户去执行

在/etc/init.d放nexus软连接

ln -s /nexus/nexus-3.29.2-02/bin/nexus /etc/init.d/nexus

运行服务

update-rc.d 参见:https://www.cnblogs.com/EasonJim/p/7573292.html

cd /etc/init.d
chmod 755 /etc/init.d/nexus  修改权限
update-rc.d nexus defaults　　设置开启启动
service nexus start 启动服务(或者关机重启)

第一次查看密码:

复制这个密码,账号:admin

第一次登录修改密码

其他Nexus操作参考

解决文件最大限制问题

vi /etc/security/limits.conf

* soft nproc 65536
* hard nproc 65536
* soft nofile 65536
* hard nofile 65536

root soft nproc 65536
root hard nproc 65536
root soft nofile 65536
root hard nofile 65536

　　数字对齐

vim /etc/pam.d/common-session-noninteractive

　　首行增加一行

session required pam_limits.so

以上都是网上乱七八糟的

这是重点,网上乱七八糟没一个好使

直接将/etc/systemd/system.conf 和 /etc/systemd/user.conf 的参数DefaultLimitNOFILE修改为65536，默认是注释的。

DefaultLimitNOFILE=65536

重启

查看

ulimit -a

idea 打包

仓库

遇到无法从私服下载jar包问题可以参考:https://blog.csdn.net/huqiankunlol/article/details/103250535

阿里仓库代理表:https://developer.aliyun.com/mvn/view

常见错误

Connect to sonatype-download.global.ssl.fastly.net:443

登陆系统》点击齿轮图标》System 》Capabilities 点击“Outreach：Management”

点击 “Disable”，之后重启 nexus

附:使用私服nexus搭建docker私有仓库:https://blog.51cto.com/215687833/5051848

1.首先确认已经安装docker,如果没有安装,请参照docker安装教程

2.登录nexus创建blob存储数据:

3.创建docker(hosted) 类型的仓库:

4.未使用https，所以定义默认的安全docker 仓库: 修改这个daemon.json文件里的ip和端口

[root@localhost nexus-data]# cat /etc/docker/daemon.json 
{
  "insecure-registries":["10.86.8.14:5000"]
}

[root@localhost nexus-data]# systemctl restart docker

5.推送遇到 no basic auth credentials
