1. Maven仓库nexus

Maven 配置仓库nexus_java

本地仓库
Maven 配置仓库nexus_intellij-idea_02

在setting.xml文件中,设置localRepository元素的值为你想连接的仓库地址即可

# cat /usr/local/maven/conf/settings.xml | grep localRepository
< localRepository

远程仓库
Maven 配置仓库nexus_xml_03

需要解压​​maven-model-builder-3.6.1.jar​​文件

/usr/local/apache-maven-3.6.1/lib/maven-model-builder-3.6.1.jar

在win上解压后的目录里查看​​xml​​文件

maven-model-builder-3.6.1\org\apache\maven\model\pom-4.0.0.xml

超级​​pom​​的信息

2. maven中配置jboss仓库

有两种方式,一种是在项目的​​pom.xml​​​中​​<repositories>​​​中添加,这是配置是针对具体的某一个项目,更多时候,我们想把​​jboss​​​仓库作为所有项目的仓库,这就需要在​​maven​​​的​​setting.xml​​​中配置了.建议将​​maven/conf/setting.xml​​​文件拷贝一份到你本地仓库的目录,作为用户配置文件。打开​​setting.xml​​文件,在里面添加一下内容:

<profiles>  
...
<profile>
<id>jboss-public-repositoryid>
<repositories>
<repository>
<id>jboss-public-repository-groupid>
<name>JBoss Public Maven Repository Groupname>
<url>https://repository.jboss.org/nexus/content/groups/public-jboss/
<layout>defaultlayout>
<releases>
<enabled>trueenabled>
<updatePolicy>neverupdatePolicy>

<snapshots>
<enabled>trueenabled>
<updatePolicy>neverupdatePolicy>

<pluginRepositories>

<id>jboss-public-repository-groupid>
<name>JBoss Public Maven Repository Groupname>
<url>https://repository.jboss.org/nexus/content/groups/public-jboss/
<layout>defaultlayout>
<releases>
<enabled>trueenabled>

<updatePolicy>neverupdatePolicy>

<activeProfiles>
<activeProfile>jboss-public-repositoryactiveProfile>

...

如果想要停用JBoss仓库,可在​​setting.xml​​​文件所在目录运行 :​​mvn -Pjboss-public-repository install​

添加插件组

3. 利用nexus搭建私有maven库

3.1 Nexus介绍

Maven 配置仓库nexus_maven_08

3.2 部署 nexus

下载nexus3.x
首先,从以下地址下载nexus:
​​​http://www.sonatype.com/download-oss-sonatype​​​ 文档:
​https://help.sonatype.com/repomanager3​​ 选择下载​​nexus-3.16.2-01-unix.tar.gz​​,适用于所有平台,本文将在​​centos7.5​​系统下安装,操作系统信息如下:

注意nexus是基于Java开发的,所以要先安装JDK8及以上:​​jdk-8u211-linux-x64.rpm​​ cnetos7系列默认就安装了jdk

==删除原来的jdk包==
# rpm -qa | grep java //查询原有rpm包
# rpm --nodeps -e java-1.8.0-openjdk-headless-1.8.0.161-2.b14.el7.x86_64 java-1.8.0-openjdk-1.8.0.161-2.b14.el7.x86_64

//删除
# rpm -qa | grep java
//检查
# rpm -ivh jdk-8u211-linux-x64.rpm
# ls /usr/java/
default jdk1.8.0_211-amd64 latest
# ls /usr/java/ -l
总用量 0
lrwxrwxrwx 1 root root 16 1 7 17:27 default -> /usr/java/latest #默认的jdk版本目录 default
drwxr-xr-x 8 root root 258 1 7 17:27 jdk1.8.0_211-amd64
lrwxrwxrwx 1 root root 28 1 7 17:27 latest -> /usr/java/jdk1.8.0_211-amd64
#
# echo $JAVA_HOME
# vim /etc/profile.d/java.sh
JAVA_HOME=/usr/java/latest
PATH=$PATH:$JAVA_HOME/bin
export JAVA_HOME PATH
# source /etc/profile
# java -version
java version "1.8.0_211"
Java(TM) SE Runtime Environment (build 1.8.0_211-b12)
Java HotSpot(TM) 64-Bit Server VM (build 25.211-b12, mixed mode)

然后 运行下面的​​youhua.sh​​命令

#/bin/bash

function ulimits(){
cat > /etc/security/limits.conf <<EOF
* soft noproc 20480
* hard noproc 20480
root soft nofile 65535
root hard nofile 65535
* soft nofile 65535
* hard nofile 65535
EOF
ulimit -n 65535
ulimit -u 20480
echo "[ulimits 配置] ==> OK"
}

function kernel(){
cat > /etc/sysctl.conf <<EOF
fs.file-max = 65535
net.ipv4.tcp_max_tw_buckets = 1000000
net.ipv4.tcp_fin_timeout = 30

net.ipv4.tcp_keepalive_probes = 3
net.ipv4.tcp_keepalive_intvl = 30
net.ipv4.tcp_syncookies = 1
net.ipv4.tcp_tw_reuse = 1
net.ipv4.tcp_tw_recycle = 1
net.ipv4.ip_local_port_range = 5000 65000
net.ipv4.tcp_mem = 786432 1048576 1572864

net.core.rmem_max = 873200
net.ipv4.tcp_wmem = 8192 436600 873200

net.core.netdev_max_backlog = 20480
net.ipv4.tcp_max_syn_backlog = 20480
net.ipv4.tcp_retries2 = 5
net.ipv4.conf.lo.arp_ignore = 0
net.ipv4.conf.lo.arp_announce = 0
net.ipv4.conf.all.arp_ignore = 0
EOF
sysctl -p >/dev/null 2>&1
echo "[内核 优化] ==> OK"
}

export -f ulimits
export -f kernel

ulimits
kernel

echo '[Success]System Init OK'
# sh +x youhua.sh

启动nexus服务
将安装包拷贝到linux操作系统路径下
解压

# tar zxvf nexus-3.16.2-01-unix.tar.gz
进入目录
# cd nexus-3.16.2-01/bin


设置systemd启动
# cat /etc/systemd/system/nexus.service
[Unit]
Description=nexus service
After=network.target

[Service]
Type=forking
LimitNOFILE=65536
ExecStart=/data/nexus-3.16.2-01/bin/nexus start
#data/nexus-3.16.2-01 需要换成实际的目录
ExecStop=/data/nexus-3.16.2-01/bin/nexus stop
User=root
Restart=on-abort

[Install]
WantedBy=multi-user.target

设置环境变量export RUN_AS_USER=root,如下:
export RUN_AS_USER=root
或者
# cat /data/nexus-3.16.2-01/bin/nexus.rc
run_as_user=root
EG:尝试使用其他用户来启动,发现都失败了,反正私服就是在内网使用,使用root启动吧

# sudo systemctl daemon-reload 重新加载配置文件
# sudo systemctl start nexus.service 启动服务

Maven 配置仓库nexus_java_09

这里提个醒,一定要注意java的版本,以及8081端口是否被占用等
Maven 配置仓库nexus_linux_10
一切顺利的话,我们在浏览器输入​​​http://192.168.56.103:8081​​​(这里192.168.56.103是nexus安装的服务器ip),即可访问nexus客户端,默认的用户名和密码:​​admin admin123​

如下图:
​​​ http://192.168.56.103:8081/​Maven 配置仓库nexus_maven_11

配置maven项目使用nexus仓库
Maven 配置仓库nexus_linux_12
Maven 配置仓库nexus_linux_13

# vim /usr/local/maven/conf/settings.xml
<mirrors>mirrors>之间加入配置信息
<mirror>
<id>nexus-myselfid>

<mirrorOf>*mirrorOf>
<name>Nexus myselfname>

Maven 配置仓库nexus_java_14
在之间加入配置信息


my-nexus

Maven 配置仓库nexus_java_15
在​​​<settings></settings>​​​之间加入下面的配置,激活使用上面的配置信息
注意:​​​Profile​​名称要和上面的相对应


my-nexus

测试

# pwd
/data/hello-world/hello-world

当我们再次执行mvn命令的时候,下载构件的地址就变为我们的地府地址了
Maven 配置仓库nexus_xml_16
私服也缓存了相对应的构件在本地仓库
