安装litecoin核心
root@ubuntu:~# wget https://download.litecoin.org/litecoin-0.16.3/linux/litecoin-0.16.3-x86_64-linux-gnu.tar.gz
root@ubuntu:~# tar -zvxf litecoin-0.16.3-x86_64-linux-gnu.tar.gz
root@ubuntu:~# install -m 0755 -o root -g root -t /usr/local/bin ./litecoin-0.16.3/bin/*
创建litecoin用户
root@iZj6caj2e6cc3idv4u55emZ:~# sudo adduser --home /home/litecoin litecoin #将litecoin用户主目录指向你的目录，然后设置账户密码
root@iZj6caj2e6cc3idv4u55emZ:~# sudo usermod -a -G sudo litecoin #将litecoin用户加入到sudo群组中
配置litecoin参数
root@iZj6caj2e6cc3idv4u55emZ:~# su - litecoin #切换到litecoin用户
litecoin@ubuntu:~$ mkdir .litecoin #创建目录
litecoin@ubuntu:~$ cd .litecoin/
litecoin@ubuntu:~$ litecoin.conf
将下面信息全部复制，并修改rpcuser（RPC用户名），rpcpassword（RPC用户密码），rpcallowip（允许访问的ip地址）然后保存
# Generated by https://jlopp.github.io/litecoin-core-config-generator/
# This config should be placed in following path:
# ~/.litecoin/litecoin.conf
# [rpc]
# Accept command line and JSON-RPC commands.
server=1
# Username for JSON-RPC connections
rpcuser=litecoinrpc
# Password for JSON-RPC connections
rpcpassword=litecoinrpc
# Listen for JSON-RPC connections on this port
rpcport=18332
# Allow JSON-RPC connections from specified source. Valid for <ip> are a single IP (e.g. 1.2.3.4),
# a network/netmask (e.g. 1.2.3.4/255.255.255.0) or a network/CIDR (e.g. 1.2.3.4/24). This option
# can be specified multiple times.
rpcallowip=192.168.1.178
rpcallowip=192.168.1.179
# Run this node on the litecoin Test Network.
testnet=1
启动litecoin程序
litecoin@ubuntu:~/.litecoin$ litecoind -daemon
Litecoin server starting
查看是否启动成功，需要输入上一步配置的密码，用户名litecoinrpc改为你配置的用户名：
litecoin@ubuntu:~$ curl --user litecoinrpc --data-binary '{"jsonrpc": "1.0", "id":"curltest", "method": "getnetworkinfo", "params": [] }' -H 'content-type: text/plain;' http://127.0.0.1:18332/
Enter host password for user 'litecoinrpc':
能返回下面的信息表示启动成功
{"result":{"version":170000,"subversion":"/Satoshi:0.17.0/","protocolversion":70015,"localservices":"000000000000040d","localrelay":true,"timeoffset":0,"networkactive":true,"connections":5,"networks":[{"name":"ipv4","limited":false,"reachable":true,"proxy":"","proxy_randomize_credentials":false},{"name":"ipv6","limited":false,"reachable":true,"proxy":"","proxy_randomize_credentials":false},{"name":"onion","limited":true,"reachable":false,"proxy":"","proxy_randomize_credentials":false}],"relayfee":0.00001000,"incrementalfee":0.00001000,"localaddresses":[],"warnings":""},"error":null,"id":"curltest"}
停止litecoin程序
litecoin@ubuntu:~/.litecoin/testnet3$ litecoin-cli stop
Litecoin server stopping
检查区块同步信息
检查同步日志（刷屏）：
litecoin@ubuntu:~/.litecoin$ cd testnet4/
litecoin@ubuntu:~/.litecoin/testnet3$ tail -f debug.log

查询当前同步到的区块数：
litecoin@ubuntu:~/.litecoin/testnet4$ curl --user litecoinrpc --data-binary '{"jsonrpc": "1.0", "id":"curltest", "method": "getblockcount", "params": [] }' -H 'content-type: text/plain;' http://127.0.0.1:18332/
Enter host password for user 'litecoinrpc':
{"result":128631,"error":null,"id":"curltest"}
查询测试网络中的总区块：http://testnet.litecointools.com/
需要注意的是只有区块同步到最新才可以查到钱包余额，从头开始同步大概需要一天时间。
创建钱包地址
litecoin@ubuntu:~$ curl --user litecoinrpc --data-binary '{"jsonrpc": "1.0", "id":"curltest", "method": "getnewaddress", "params": ["test"] }' -H 'content-type: text/plain;' http://127.0.0.1:18332/
Enter host password for user 'litecoinrpc':
{"result":"QNuZnYa45hWRpsJz4SYwAEQfZS9UBc2j6L","error":null,"id":"curltest"}
返回结果中的 “QNuZnYa45hWRpsJz4SYwAEQfZS9UBc2j6L” 即为新创建的莱特币钱包地址
获取测试币
在下面两个网站中可以获得少量的测试币，用来测试足够了：
http://testnet.litecointools.com/
你可以在莱特币区块链浏览器查到余额
http://explorer.litecointools.com/address/QNuZnYa45hWRpsJz4SYwAEQfZS9UBc2j6L
