公司使用国外maven源很慢，打算使用本地仓库解决依赖问题，这里搭建很简单，直接把全部命令贴上来了，一步步执行即可
maven仓库使用nexus来进行搭建，依赖jdk对应版本，步骤如下
yum -y install java-1.7.0-openjdk*
tar xzvf apache-maven-3.3.9-bin.tar.gz -C /mnt/sdb/
echo ‘export JAVA_HOME=/usr/lib/jvm/java-1.7.0-openjdk-1.7.0.131.x86_64‘>>/etc/profile
echo ‘export MAVEN_HOME=/mnt/sdb/apache-maven-3.3.9‘>>/etc/profile
echo ‘export PATH=$PATH:$JAVA_HOME/bin:$MAVEN_HOME/bin‘>>/etc/profile
echo ‘export CLASSPATH=.:$JAVA_HOME/lib.dt.jar:$JAVA_HOME/lib/tools.jar‘>>/etc/profile
. /etc/profile
tar xf nexus-2.14.3-02-bundle.tar.gz -C /mnt/sdb/
sed -i ‘/#RUN_AS_USER=/s/#RUN_AS_USER=/RUN_AS_USER=root/g‘ /mnt/sdb/nexus-2.14.3-02/bin/nexus
chmod +x /mnt/sdb/nexus-2.14.3-02/bin/nexus
ln -s /mnt/sdb/nexus-2.14.3-02/bin/nexus /etc/init.d/nexus
http://10.47.89.159:8081/nexus/
admin
admin123
vim /etc/init.d/nexus添加
# chkconfig: 2345 27 87
# description: Saves and restores system entropy pool for \
# higher quality random number generation.
chkconfig nexus on
登陆管理员修改密码即可
另外可以配置nginx代理
#本地私有maven仓库，使用nexus管理
location ^~ /nexus/ {
proxy_set_header Host $http_host;
proxy_set_header X-Forward-For $remote_addr;
proxy_pass http://10.47.89.159:8081/nexus/;
