EOS初始化

1.插件静态区初始化
static appbase::abstract_plugin& _chain_api_plugin = app().register_plugin<chain_api_plugin>();
static appbase::abstract_plugin& _db_size_api_plugin = app().register_plugin<db_size_api_plugin>();

2.启动
1.初始化application单例,设置版本号
constexpr uint64_t version = 0x1a14e9cd;

2.设置app_path,mac中的数据目录和配置目录分别为:
/Users/xj/Library/Application Support/eosio/nodeos/data
/Users/xj/Library/Application Support/eosio/nodeos/config

3.http插件设置端口为8888

4.自动启动的插件有:chain_plugin, net_plugin, producer_plugin

5.从配置文件(config.ini)读取需额外启动的插件进行初始化,如果插件已注册,则通过访问者进行注册,并初始化所依赖的插件
filter-on = * //注意这里是*,而不是'*',系统自带的文件有误
plugin = eosio::chain_api_plugin
plugin = eosio::history_plugin
plugin = eosio::history_api_plugin


#define APPBASE_PLUGIN_REQUIRES_VISIT( r, visitor, elem ) \
  visitor( appbase::app().register_plugin<elem>() );

#define APPBASE_PLUGIN_REQUIRES( PLUGINS )                               \
   template<typename Lambda>                                           \
   void plugin_requires( Lambda&& l ) {                                \
      BOOST_PP_SEQ_FOR_EACH( APPBASE_PLUGIN_REQUIRES_VISIT, l, PLUGINS ) \
   }

APPBASE_PLUGIN_REQUIRES((chain_plugin)(http_plugin)) //如chain_api_plugin需要依赖这两个插件

6.启用插件,插件初始化
