这两天简单运行了一下cleos连接EOS主网，但是连接网上节点经常会断，返回数据也比较慢，如果想用得开心点还是得自己跑节点了！
在网上看到很多都是运行本地测试节点，其实我更需要的是同步公共节点数据，找到一两篇文章按其方式完成了了同步节点的配置，记录一下。
如果还没有nodeos、cleos参考：EOS研究系列【mac下编译运行】
下载区块链创世文件genesis.json，位置为：https://github.com/EOS-Mainnet/eos/blob/launch-rc-1.0.2/mainnet-genesis.json ，看内容不多直接粘贴下来，方便使用，如下：
{
"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
}
}
看起来这个文件和Bitshares差别还是挺大的，把这个文件拷贝到自己放eos数据目录下：
(env3) Chaim:~ Chaim$ mkdir eosdata
(env3) Chaim:~ Chaim$ vi genesis.json
genesis.json放上刚下载的内容，我们把目录建在用户根目录下，没有在代码目录下，因为代码目录经常清或重编容易弄丢。
先执行下面命令在用户目录/eosdata下生成config.ini，执行几秒“Ctrl+C”即可：
Chaim:nodeos Chaim$ ./nodeos -d ~/eosdata/generator_node --config-dir ~/eosdata/generator_node --plugin eosio::wallet_api_plugin --plugin eosio::chain_api_plugin --p2p-listen-endpoint localhost:5555
编辑~/eosdata/generator_node/config.ini文件，增加p2p节点，节点可以在这取到，太多不全列出，如下节点亲测可用：
p2p-peer-address = 54.38.250.15:19878
p2p-peer-address = mainnet.eospay.host:19876
p2p-peer-address = peer.eosn.io:9876
p2p-peer-address = node.eosflare.io:1883
p2p-peer-address = eos.staked.us:9870
可能很多节点连不上，这还有一份列表，看日志把连接出错的给删除吧！
同样的config.ini，增加以下plugins：
plugin = eosio::producer_plugin
plugin = eosio::wallet_api_plugin
plugin = eosio::chain_api_plugin
plugin = eosio::http_plugin
plugin = eosio::history_api_plugin
这一项改不改都行，如果keosd没有占用的话就不用改：
# The local IP and port to listen for incoming http connections; set blank to disable. (eosio::http_plugin)
http-server-address = 127.0.0.1:8899
./nodeos -d ~/eosdata/generator_node --config-dir ~/eosdata/generator_node --genesis-json ~/eosdata/genesis.json --delete-all-blocks
以后启动就不需要“--genesis-json”和“--delete-all-blocks”参数了！
直到出现类似以下提示表明已经接收到数据包：
2515041ms thread-0 producer_plugin.cpp:290 on_incoming_block ] Received block ddc03486114e6a1c... #1000 @ 2018-06-09T12:06:33.000 signed by eosio [trxs: 1, lib: 999, conf: 0, latency: 2345722041 ms]
不过这些节点在国内连起来很多都有问题，不知道是网络问题呢还是节点问题！同步了一天数据才同步完成！
(env3) Chaim:cleos Chaim$ ./cleos -u http://127.0.0.1:8899 get info
早两天用网上节点取块数据经常一会就卡住，现在用本地节点应该不会有这些问题了吧！
同步得好好的，突然退出了，需要“replay”，replay就是区块数据重新跑一遍，可千万不要重新下载区块啊，都跑一天了！
libc++abi.dylib: terminating with uncaught exception of type boost::exception_detail::clone_impl<boost::exception_detail::error_info_injector<std::logic_error> >: Could not restore object, most likely a uniqueness constraint was violated
./pub.sh: line 1: 78500 Abort trap: 6 ./nodeos -d ~/eosdata/generator_node --config-dir ~/eosdata/generator_node

2434000ms thread-0 main.cpp:123 main ] database dirty flag set (likely due to unclean shutdown): replay required
加上“--replay-blockchain”参数还是出错：
Chaim:nodeos Chaim$ ./nodeos -d ~/eosdata/generator_node --config-dir ~/eosdata/generator_node --replay-blockchain
3086942ms thread-0 chain_plugin.cpp:209 plugin_initialize ] initializing chain plugin

3087788ms thread-0 main.cpp:123 main ] database dirty flag set (likely due to unclean shutdown): replay required
还有一招“--hard-replay-blockchain”先试试：
Chaim:nodeos Chaim$ ./nodeos -d ~/eosdata/generator_node --config-dir ~/eosdata/generator_node --replay-blockchain --hard-replay-blockchain
3178561ms thread-0 chain_plugin.cpp:209 plugin_initialize ] initializing chain plugin

结果很慢的执行还是出错了，最终没有办法重新走第一次启动的过程，删除全部区块重来！
