--------------------

# 一、Nexus介绍 #

对maven来说仓库分为两类：本地仓库和远程仓库，有三种专门的Maven仓库管理软件可以用来帮助我们建立私服：chiva、Artifactory和Nexus。Nexus是当前最流行的Maven仓库管理软件。Nexus包含了各种类型的仓库的概念，包括代理仓库、宿主仓库、仓库组等。每一种仓库都提供了丰富实用的配置参数，方便用户根据需要进行定制。

# 二、2.X环境安装部署 #

这里以2.X最新版为例，版本号2.14.16

## 1、Nexus官网下载地址 ##

[https://www.sonatype.com/download-oss-sonatype][https_www.sonatype.com_download-oss-sonatype]

2.X版本下载地址：[https://help.sonatype.com/repomanager2/download][https_help.sonatype.com_repomanager2_download]

3.X版本下载地址：[https://help.sonatype.com/repomanager3/download][https_help.sonatype.com_repomanager3_download]

## 2、解压到本地  ##

tar -xzvf nexus-2.14.16-01-bundle.tar.gz

## 3、修改Nexus端口（默认为8081） ##

我这里查询端口已经占用了，所以需要修改端口，vi nexus.properties，这里修改application-port为8090

[root@yang opt]# netstat -aon | grep "8081"
    tcp6       0      0 :::8081                 :::*                    LISTEN      off (0.00/0/0)
    [root@yang opt]# lsof -i :8081

    jsvc    17634  web   49u  IPv6 63482708      0t0  TCP *:tproxy (LISTEN)
    [root@yang opt]# ps -ef | grep 17634

[root@yang conf]# vi nexus.properties

## 4、开放防火墙 ##

vi /etc/sysconfig/iptables

添加：-A INPUT -p tcp -m state --state NEW -m tcp --dport 8090 -j ACCEPT

service   iptables restart

## 5、修改启动文件 ##

/opt/nexus-2.14.16-01/bin/nexus添加root启动，或者添加nexus用户（useradd nexus），

否则启动报错If you insist running as root, then set the environment variable RUN\_AS\_USER=root before running this script.

修改RUN\_AS\_USER=root  //注意删除前面的\#号

修改JDK路径vi wrapper.conf（./bin/jsw/conf/wrapper.conf）

修改参数wrapper.java.library.path.1=/opt/jdk1.8.0\_151/bin/

##    6、启动 ##

/opt/nexus-2.14.16-01/bin/nexus

[root@yang bin]# ./nexus start &
    [1] 2514
    [root@yang bin]# ****************************************
    WARNING - NOT RECOMMENDED TO RUN AS ROOT

    [1]+  Done                    ./nexus start
    [root@yang bin]# ps -ef | grep nexus
    root      2558     1  0 14:03 ?        00:00:00 /opt/nexus-2.14.16-01/bin/../bin/jsw/linux-x86-64/wrapper /opt/nexus-2.14.16-01/bin/../bin/jsw/conf/wrapper.conf wrapper.syslog.ident=nexus wrapper.pidfile=/opt/nexus-2.14.16-01/bin/../bin/jsw/linux-x86-64/nexus.pid wrapper.daemonize=TRUE wrapper.lockfile=/var/lock/subsys/nexus

## 7、访问nexus ##

[http://ip地址:8090/nexus/][http_ip_8090_nexus]   默认账号和密码：admin/admin123

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3hseXJo_size_16_color_FFFFFF_t_70][]

# 三、3.X环境安装部署 #

3.x和2.x有一些差异，这里也一并记录一下

3.X版本下载地址：[https://help.sonatype.com/repomanager3/download][https_help.sonatype.com_repomanager3_download]

## 1、解压 ##

tar  -xzvf nexus-3.21.2-03-unix.tar.gz

解压后是两个文件夹nexus-3.21.2-03和sonatype-work

## 2、修改Nexus默认端口 ##

路径有小变动，配置文件在/opt/nexus-3.21.2-03/etc路径下vi nexus-default.properties

这里修改为application-port=8091

## 3、开防火墙 ##

vi /etc/sysconfig/iptables

添加：-A INPUT -p tcp -m state --state NEW -m tcp --dport 8091 -j ACCEPT

service   iptables restart

## 4、添加启动用户 ##

经测试，使用root启动问题还挺多的，这里添加nexus用户启动

useradd nexus

修改文件所属用户及用户组：

chown -R nexus:nexus /opt/nexus-3.21.2-0

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

drwxr-xr-x 9 nexus nexus      4096 Mar 24 20:09 nexus-3.21.2-03
    -rw-r--r-- 1 root  root  140760762 Mar 24 17:33 nexus-3.21.2-03-unix.tar.gz
    drwxr-xr-x 5 nexus nexus      4096 Mar 25 14:29 sonatype-work

## 5、启动nexus ##

./nexus run    或者后台运行   nohup ./bin/nexus run > logs/nexus.log 2>&1 &

出现如下信息时启动成功，可以通过网页访问

-------------------------------------------------
    
    Started Sonatype Nexus OSS 3.21.2-03
    
    -------------------------------------------------

问题解决：

若启动时报如下错误

2020-03-25 14:11:40,914+0800 ERROR [ForkJoinPool.commonPool-worker-1] *SYSTEM com.orientechnologies.orient.core.storage.impl.local.paginated.OLocalPaginatedStorage - Exception `4BCD73AB` in storage `plocal:/opt/sonatype-work/nexus3/db/config`: 2.2.36 (build d3beb772c02098ceaea89779a7afd4b7305d3788, branch 2.2.x)
    com.orientechnologies.orient.core.exception.OStorageException: Storage config is not opened.
            DB name="config"

解决方法：

将sonatype-work/下的nexus3重命名或者删除，再重启（参考文献：[https://www.cnblogs.com/ccbloom/p/10932822.html][https_www.cnblogs.com_ccbloom_p_10932822.html]）

[nexus@yang opt]$ cd sonatype-work/
    [nexus@yang sonatype-work]$ ls
    nexus  nexus3  README.txt
    [nexus@yang sonatype-work]$ mv nexus3/ nexus3_backup
    [nexus@yang sonatype-work]$ ll
    total 12
    drwxr-xr-x 15 nexus nexus 4096 Mar 24 21:41 nexus

    -rw-r--r--  1 nexus nexus  350 Jan 15 03:57 README.txt

## 6、访问3.X版本Nexus ##

地址：[http://IP地址:8091/][http_IP_8091]   用户名为admin，密码在cat /opt/sonatype-work/nexus3/admin.password，首次登陆后需要修改密码

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3hseXJo_size_16_color_FFFFFF_t_70 1][]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3hseXJo_size_16_color_FFFFFF_t_70 2][]

问题解决：

后台报错异常：

2020-03-25 15:19:01,965+0800 WARN  \[qtp356953667-47\] admin com.sonatype.nexus.plugins.outreach.internal.outreach.SonatypeOutreach - Could not download page bundle  
org.apache.http.conn.ConnectTimeoutException: Connect to sonatype-download.global.ssl.fastly.net:443 \[sonatype-download.global.ssl.fastly.net/31.13.72.17\] failed: connect timed out

解决方法：

打开【System】==>【Capabilities】，将【Outreach:Management】禁用即可

重设密码：
