nexus配置https（在nexus上配置jks证书方式）：
cd /usr/local/nexus3/etc/ssl/
将已有的.crt和.key证书文件转为p12格式：
openssl pkcs12 -export -out keystore.pkcs12 -inkey ming.key -in ming.crt
设置密码
再将p12格式文件转为.jks格式：
keytool -v -importkeystore -srckeystore keystore.pkcs12 -srcstoretype PKCS12 -destkeystore keystore.jks -deststoretype JKS
输入上步设置的密码并设置新密码（可同上步密码）
chown nexus:nexus /usr/local/nexus3/etc/ssl/keystore.jks
vi /usr/local/nexus3/etc/nexus-default.properties
DO NOT EDIT - CUSTOMIZATIONS BELONG IN $data-dir/etc/nexus.properties
