1. Maven仓库nexus
本地仓库
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
<!-- | The path to the local repository maven will use to store artifacts.
|
| Default: ${user.home}/.m2/repository
-->
<localRepository>/path/to/local/repo</localRepository>
远程仓库
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
<repositories>
<repository>
<id>central</id>
<name>Central Repository</name>
<url>https://repo.maven.apache.org/maven2</url>
<layout>default</layout>
<snapshots>
<enabled>false</enabled>
</snapshots>
</repository>
</repositories>
配置使用远程仓库
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-repository</id>
<repositories>
<repository>
<id>jboss-public-repository-group</id>
<name>JBoss Public Maven Repository Group</name>
<url>https://repository.jboss.org/nexus/content/groups/public-jboss/</url>
<layout>default</layout>
<releases>
<enabled>true</enabled>
<updatePolicy>never</updatePolicy>
</releases>
<snapshots>
<enabled>true</enabled>
<updatePolicy>never</updatePolicy>
</snapshots>
</repository>
</repositories>
<!-- 插件仓库 -->
<pluginRepositories>
<pluginRepository>
<id>jboss-public-repository-group</id>
<name>JBoss Public Maven Repository Group</name>
<url>https://repository.jboss.org/nexus/content/groups/public-jboss/</url>
<layout>default</layout>
<releases>
<enabled>true</enabled>
<updatePolicy>never</updatePolicy>
</releases>
<!-- 不下载快照版 -->
<snapshots>
<enabled>false</enabled>
<updatePolicy>never</updatePolicy>
</snapshots>
</pluginRepository>
</pluginRepositories>
</profile>
</profiles>
<!-- 默认为激活状态-->
<activeProfiles>
<activeProfile>jboss-public-repository</activeProfile>
</activeProfiles>
...
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
<pluginGroups>
...
<pluginGroup>org.jboss.maven.plugins</pluginGroup>
...
</pluginGroups>
3. 利用nexus搭建私有maven库
3.1 Nexus介绍
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月 7 17:27 default -> /usr/java/latest #默认的jdk版本目录 default
drwxr-xr-x 8 root root 258 1月 7 17:27 jdk1.8.0_211-amd64
lrwxrwxrwx 1 root root 28 1月 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.wmem_max = 873200
net.core.rmem_max = 873200
net.ipv4.tcp_wmem = 8192 436600 873200

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
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
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/
配置maven项目使用nexus仓库
# vim /usr/local/maven/conf/settings.xml
在<mirrors></mirrors>之间加入配置信息
<mirror>
<id>nexus-myself</id>
<!--* 指的是访问任何仓库都使用我们的私服 -->
<mirrorOf>*</mirrorOf>
<name>Nexus myself</name>
<url>http://192.168.137.102:8081/repository/maven-public/</url>
</mirror>
在之间加入配置信息
<profile>
<id>my-nexus</id>
<repositories>
<!--私有库地址 -->
<repository>
<id>nexus</id>
<name>nexus</name>
<url>http://192.168.137.102:8081/repository/maven-public/</url>
<snapshots>
<enabled>true</enabled>
</snapshots>
<releases>
<enabled>true</enabled>
</releases>
</repository>
</repositories>
<pluginRepositories>
<!-- 插件库地址 -->
<pluginRepository>
<id>nexus</id>
<url>http://192.168.137.102:8081/repository/maven-public/</url>
<releases>
<enabled>true</enabled>
</releases>
<snapshots>
<enabled>true</enabled>
</snapshots>
</pluginRepository>
</pluginRepositories>
</profile>
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
<activeProfiles>
<activeProfile>my-nexus</activeProfile>
</activeProfiles>
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
私服也缓存了相对应的构件在本地仓库
