1、解压nexus压缩包
tar xvzf ./nexus-2.13.0-01-bundle.tar.gz
2、修改配置文件：
修改jetty配置
[root@localhost nexus]# vim nexus-2.13.0-01/bin/nexus
# Set this to the root of the Nexus installation
#NEXUS_HOME=".." #将这行注释掉，修改为下边的，
NEXUS_HOME="/home/nexus/nexus-2.13.0-01"
# If specified, the Wrapper will be run as the specified user.
# IMPORTANT - Make sure that the user has the required privileges to write into the Nexus installation directory.
# NOTE - This will set the user which is used to run the Wrapper as well as
# the JVM and is not useful in situations where a privileged resource or
# port needs to be allocated prior to the user being changed.
#RUN_AS_USER=
RUN_AS_USER=root #添加这行
# Application
APP_NAME="nexus"
APP_LONG_NAME="Nexus OSS"
3、将nexus设置为开机启动
[root@localhost nexus]# cd nexus-2.13.0-01/bin
[root@localhost bin]# cp ./nexus /etc/rc.d/init.d/
[root@localhost bin]# cd /etc/rc.d/init.d/
[root@localhost init.d]# chkconfig --add nexus
[root@localhost init.d]# chkconfig --list | grep nexus
nexus 0:off 1:off 2:on 3:on 4:on 5:on 6:off
[root@localhost init.d]# chkconfig nexus on
[root@localhost init.d]# chkconfig --list | grep nexus
nexus 0:off 1:off 2:on 3:on 4:on 5:on 6:off
4、开放端口8081
-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 8081 -j ACCEPT
重启端口服务
service iptables restart
