位于

連接主網需要修改該配置文件

plugin = eosio::chain_api_plugin ? plugin = eosio::history_plugin ? plugin = eosio::history_api_plugin ? plugin = eosio::chain_plugin ? plugin = eosio::bnet_plugin
網上可以找到的一些老教程里面可能還包含了wallet的插件，實測不需要，如果裝了反而跑不起來
還需要把節(jié)點加進來，這里是一份所有節(jié)點的清單，這里是份標準的config.ini模板可供參考。實測peer的多少并不能對同步區(qū)塊的速度造成很大的影響，少一點多一點無所謂。
啟動nodeos連接主網
下面是幾種啟動nodeos的常用方式，但是不建議試用
./nodeos：只能在nodeos所在的位置啟動，./表示當前文件夾-
nodeos：配置完環(huán)境變量后的啟動方式，跟上一條結果一樣，區(qū)別是在任何位置都可以用配置臨時環(huán)境變量的格式樣例：
export PATH=$PATH:/home/eos_install/eos/build/programs/nodeos ./nodeos -e -p eosio --plugin eosio::chain_api_plugin --plugin eosio::history_api_plugin：指定了兩個插件，如果上面已經配置了config.ini就不需要再指定了
建議使用下面一條命令啟動nodeos
-
nodeos --data-dir=/home/eos_install/eos/data/packages/nodeos --config-dir=/home/eos_install/eos/data/packages/nodeos--data-dir指定了data的存儲位置，也就是block的位置，--config-dir指定了config.ini的位置，如果是第一次啟動的話，可以在后面加上--genesis-json genesis.json指定genesis.josn文件位置。
