HOW TO fix openLDAP checksum error on config files
(source : http://injustfiveminutes.com/category/openldap)
How to fix “ldif_read_file: checksum error”
Posted on October 28, 2014

Well, in spite of you did read a banner saying “# AUTO-GENERATED FILE – DO NOT EDIT!! Use ldapmodify.” you ignored it and made some manual modifications in any of the LDIF files in /etc/ldap/slapd.d/.
Don’t worry it happened to me too :) When you need to quickly setup an openLDAP server for development it is pretty much easier to tweak these files although the recommended way is to use ldapmodify tool. But if you change the LDIF files in cn=config manually, their contents and checksums won’t match, which is not fatal, but is annoying when using tools such as slapcat:

MongoDB Setting Markdown

MongoDB Shard Setting

1.서버 데몬의 구성

본 문서는 기본 샤딩의 개념을 실습하고 학습하는 데에 목표를 두고 3대의 서버를 둔다는 가정하에 한대의 물리적인 서버에 샤딩을 구성하며 Sharding 의 Rule 이라고 볼 수 있는 Collectoin의 Shard Chunk 구성은 하지 않는다.

각 싸이트마다 데이터의 규칙을 살펴보고 Chunk 구성까지 하여야 하며 Autosharding 은 가급적 구성하지 않는 것으로 한다.

>Sharding이 되는 기본 데몬, 옵션에 따라 configsvr 또는 shardsvr로 나뉘게 된다.
