nexus 安装 配置 启动

安装 JDK

运行 Nexus 需要 Java 8 的运行时环境支持，可以使用 YUM 方式安装安装 open JDK1.8版本，也可以使用 rpm 安装，

我们课程使用 RPM 方式安装 

[root@ci-node3 src]# rpm -ivh jdk-8u121-linux-x64.rpm

java安装好了

[root@ci-node3 src]# java -version
java version "1.8.0_121"
Java(TM) SE Runtime Environment (build 1.8.0_121-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.121-b13, mixed mode)

启动nexus 

上面启动成功后会警告不要使用 root 用户启动，这里可以新建一个用户，也可以指定
root 用户启动，使他不出现警告，

下面配置指定 root 用户启动,编辑 bin 目录下的 nexus.rc  启动配置文件

[root@ci-node3 bin]# cat nexus.rc 
#run_as_user=""

[root@ci-node3 bin]# pwd
/usr/local/nexus/bin
[root@ci-node3 bin]# vim nexus.rc 

修改内容为：

run_as_user="root

然后wq保存

可以这样使用

[root@ci-node3 bin]# ./nexus 
WARNING: ************************************************************
