## Quick Primer on addnode vs connect ##
## Let's say for instance you use addnode=4.2.2.4 ##
## addnode will connect you to and tell you about the ##
## nodes connected to 4.2.2.4. In addition it will tell ##
## the other nodes connected to it that you exist so ##
## they can connect to you. ##
## connect will not do the above when you 'connect' to it. ##
## It will *only* connect you to 4.2.2.4 and no one else.##
## ##
## So if you're behind a firewall, or have other problems ##
## finding nodes, add some using 'addnode'. ##
## ##
## If you want to stay private, use 'connect' to only ##
## connect to "trusted" nodes. ##
## ##
## If you run multiple nodes on a LAN, there's no need for ##
## all of them to open lots of connections. Instead ##
## 'connect' them all to one node that is port forwarded ##
## and has lots of connections. ##
## Thanks goes to [Noodle] on Freenode. ##

# Use as many addnode= settings as you like to connect to specific peers

#server=0
# Bind to given address to listen for JSON-RPC connections. Use [host]:port notation for IPv6.
# This option can be specified multiple times (default: bind to all interfaces)
#rpcbind=<addr>
# If no rpcpassword is set, rpc cookie auth is sought. The default `-rpccookiefile` name
# is .cookie and found in the `-datadir` being used for bitcoind. This option is typically used
# when the server and client are run as the same user.
#
# If not, you must set rpcuser and rpcpassword to secure the JSON-RPC api. The first
# method(DEPRECATED) is to set this pair for the server and client:
#rpcuser=Ulysseys
#rpcpassword=YourSuperGreatPasswordNumber_DO_NOT_USE_THIS_OR_YOU_WILL_GET_ROBBED_385593
#
# The second method `rpcauth` can be added to server startup argument. It is set at intialization time
# using the output from the script in share/rpcuser/rpcuser.py after providing a username:
#
# ./share/rpcuser/rpcuser.py alice
# String to be appended to bitcoin.conf:
# rpcauth=alice:f7efda5c189b999524f151318c0c86$d5b51b3beffbc02b724e5d095828e0bc8b2456e9ac8757ae3211a5d9b16a22ae
# Your password:
# DONT_USE_THIS_YOU_WILL_GET_ROBBED_8ak1gI25KFTvjovL3gAM967mies3E=
#
# On client-side, you add the normal user/password pair to send commands:
#rpcuser=alice
#rpcpassword=DONT_USE_THIS_YOU_WILL_GET_ROBBED_8ak1gI25KFTvjovL3gAM967mies3E=
#
# You can even add multiple entries of these to the server conf file, and client can use any of them:
# rpcauth=bob:b2dd077cb54591a2f3139e69a897ac$4e71f08d48b4347cf8eff3815c0e25ae2e9a4340474079f55705f40574f4ec99

# Specify as many rpcallowip= settings as you like to allow connections from other hosts,

## txindex option to get full transactions synced
```
Transaction Database Index and txindex Option
By default, Bitcoin Core builds a database containing only the transactions related to the user’s wallet. If you want to be able to access any transaction with commands like gettransaction, you need to configure Bitcoin Core to build a complete transaction index, which can be achieved with the txindex option. Set txindex=1 in the Bitcoin Core configuration file
```
https://bitcoin.stackexchange.com/questions/35707/what-are-pros-and-cons-of-txindex-option
在配置中开启后，使用命令 bitcoind -reindex启动，重建数据库,然后用getrawtransaction才能查到数据
```

使用`bitcoind -daemon`就好，不要总是使用`bitcoind -reindex -daemon`
因为reindex会重新获取链上数据：
