安装EOS

yum安装

由于编译安装耗时较长且过程中容易中容易出问题，所以还是推荐使用yum方式安装，这里安装的是1.8.6版本。

wget https://github.com/EOSIO/eos/releases/download/v1.8.6/eosio-1.8.6-1.el7.x86_64.rpm
sudo yum install ./eosio-1.8.6-1.el7.x86_64.rpm

配置文件

Linux下的配置文件位置 ~/.local/share/eosio/nodeos/config/

config.ini ，配置peer节点和plugins

chain-state-db-size-mb = 102400 //这个得设置大一点，默认1024

plugin = eosio::chain_api_plugin

plugin = eosio::history_api_plugin

plugin = eosio::chain_plugin

plugin = eosio::history_plugin

plugin = eosio::net_plugin

plugin = eosio::net_api_plugin

genesis.json


{
  "initial_timestamp": "2018-06-08T08:08:08.888",
  "initial_key": "EOS7EarnUhcyYqmdnPon8rm7mBCTnBoot6o7fE2WzjvEX2TdggbL3",
  "initial_configuration": {
    "max_block_net_usage": 1048576,
    "target_block_net_usage_pct": 1000,
    "max_transaction_net_usage": 524288,
    "base_per_transaction_net_usage": 12,
    "net_usage_leeway": 500,
    "context_free_discount_net_usage_num": 20,
    "context_free_discount_net_usage_den": 100,
    "max_block_cpu_usage": 200000,
    "target_block_cpu_usage_pct": 1000,
    "max_transaction_cpu_usage": 150000,
    "min_transaction_cpu_usage": 100,
    "max_transaction_lifetime": 3600,
    "deferred_trx_expiration_window": 600,
    "max_transaction_delay": 3888000,
    "max_inline_action_size": 4096,
    "max_inline_action_depth": 4,
    "max_authority_depth": 6
  }
}

启动进程

//第一次启动需要指定genesis.json文件
./nodeos --genesis-json genesis.json

//以后启动
nodeos > /dev/null 2>&1 &

启动看通过cleos get info查看chain_id是否是

aca376f206b8fc25a6ed44dbdc66547c36c6c33e3a119ffbeaef943642f0e906

以确保节点是在主网上同步数据。

Linux下的节点数据目录 ~/.local/share/eosio/nodeos/data/，genesis.json文件变动时，需要清空该目录下的文件。

钱包交互

创建钱包

# cleos wallet create --to-console

Creating wallet: default
Save password to use in the future to unlock this wallet.
Without password imported keys will not be retrievable.
"PW5KQSBWzJCt1kSZnH1UW6cLiU5HpftmkRiXcpxi7A5dGECFyN7nq"

解锁

# cleos wallet unlock --password PW5KQSBWzJCt1kSZnH1UW6cLiU5HpftmkRiXcpxi7A5dGECFyN7nq

加锁

# cleos wallet lock

创建owner密钥对

# cleos create key --to-console
Private key: 5K9RowyzRHnhAFcbe3PPaoy1KMKcXadybEFoNC4Gpbga4ak6H1Y
Public key: EOS7nyAheoTBLSVj7NL24dU9r4rPgdTT1aPiRNexeueiBsMXoapro

创建active密钥对

# cleos create key --to-console
Private key: 5KHjf1QKTAGZ3nD5E5rSNw65wx33AqgV8BzUK7RwJ6zdNAmSjp6
Public key: EOS8NTgeris3xhTS6dtSgn4FhCu1NqeXvdk1PzEKNjFbEx7viK4CX

导入owner和active密钥到钱包

# cleos wallet import --private-key 5K9RowyzRHnhAFcbe3PPaoy1KMKcXadybEFoNC4Gpbga4ak6H1Y
imported private key for: EOS7nyAheoTBLSVj7NL24dU9r4rPgdTT1aPiRNexeueiBsMXoapro

#cleos wallet import --private-key 5KHjf1QKTAGZ3nD5E5rSNw65wx33AqgV8BzUK7RwJ6zdNAmSjp6
imported private key for: EOS8NTgeris3xhTS6dtSgn4FhCu1NqeXvdk1PzEKNjFbEx7viK4CX

创建账号

# cleos create account eosio cdcgogo EOS7nyAheoTBLSVj7NL24dU9r4rPgdTT1aPiRNexeueiBsMXoapro EOS8NTgeris3xhTS6dtSgn4FhCu1NqeXvdk1PzEKNjFbEx7viK4CX

Error 3090003: Provided keys, permissions, and delays do not satisfy declared authorizations
Ensure that you have the related private keys inside your wallet and your wallet is unlocked.

貌似需要节点完全同步后才可以创建，因为创建账号是同步到全网络的。

创建账户时购买RAM，同时抵押CPU和NET

cleos system newaccount --stake-net '1 EOS' --stake-cpu '1 EOS' --buy-ram-kbytes 20 eosio cdcgogo EOS7nyAheoTBLSVj7NL24dU9r4rPgdTT1aPiRNexeueiBsMXoapro EOS8NTgeris3xhTS6dtSgn4FhCu1NqeXvdk1PzEKNjFbEx7viK4CX

购买RAM

cleos system buyram cdcgogo cdcgogo "10 EOS"

抵押NET和CPU

cleos system delegatebw cdcgogo cdcgogo "10 EOS" "10 EOS"

最后两个参数是net和cpu要抵押的量，其中一个可为0

获取账号信息

# cleos get account cdcgogo

转账

cleos transfer from_account to_account "10 EOS" "memo"

启动Keosd

keosd --config-dir "/root/.local/share/eosio/keosd"
//keosd目录是自己创建的，方便起见和nodeos目录放在一起

keosd配置 config.ini，放到上文的目录下。

http-server-address= 0.0.0.0:8889
access-control-allow-origin = "*" 
wallet-dir = "/root/eosio-wallet"
access-control-allow-credentials =  false
http-validate-host = 0
unix-socket-path = keosd.sock

其实就是把 1.3版本之前 nodeos config.ini中的一部分拿过来. 1.3版本之后，nodeos和keosd独立开来， nodeos config.ini不再包含 wallet-dir和unlock-timeout两项，所以nodeos的api也不再包含/v1/wallet，需要为keosd另外配置一个http端口。
