1：拷贝security.json到目录webapps/solr_home/下，security.json的内容如下：
{
"authentication":{
"blockUnknown":true,
"class":"solr.BasicAuthPlugin",
"credentials":{
"solr":"IV0EHq1OnNrj6gvRCwvFwTrZ1+z1oBbnQdiVC3otuq0= Ndd7LKvVBAaZIF0QAVi1ekCfAJXr1GGfLtRUXhgrF8c="
},
"":{"v":0}},
"authorization":{
"class":"solr.RuleBasedAuthorizationPlugin",
"permissions":[{
"name":"security-edit",
"role":"admin"}],
"user-role":{"solr":"admin"}}}
###以上代表solr的用户名和密码为: solr/SolrRocks
2: 启动solr
3: 修改用户名密码（需要借助curl工具）
##修改solr登录密码
curl --user solr:SolrRocks http://192.168.1.176:9081/solr/admin/authentication -H "Content-type:application/json" -d "{\"set-user\": {\"king\" : \"123456\"}}"
##删除solr用户
curl --user solr:SolrRocks http://192.168.1.176:9081/solr/admin/authentication -H "Content-type:application/json" -d "{\"delete-user\": \\"solr\\"}"
##查看权限
