VNODE节点命令行

常用的命令行参数：

--testnet: connect to MOAC testnet (networkid = 101);

--rpc: initiate RPC service of HTTP, so as to nonlocally access the specific MOAC node service;

--rpcaddr value: default as "localhost", only local accessibility; can be reset to "0.0.0.0", so as to nonlocally access the specific MOAC node service, but the current RPC service is based on HTTP using plaintext，so users need to be aware of the safety risks;

--rpcport value: default as"8545", normally no changes are needed, users can use the default port;

--rpcapi value: command RPC as to which API service will be open，default as "chain3,mc,net"，the commonly used will also be configured such as: personal,admin,debug,miner,txpool,db,shh and so on，but because of RPC services' cleartext nature，if users choose to use personal，they should be aware of the safety risks；

--rpccorsdomain value: in general，if users wish to use this option, they can just use ""; to be more specifical, users are recommended to search up "Cross-origin resource sharing" to further understand some key phrases;

--jspath loadScript: default value is ".", the main directory of loadScript when installing javascript file；

As shown below：

初始化启动VNODE节点，默认连接到 MOAC 主网(network ID = 99)：

./moac

Through local ipc port connecting to MOAC mainnet nodes and start the command line

./moac attach

./moac --testnet

Initiate MOAC testnet nodes and interactive command line

./moac --testnet console

Through local ipc port connecting to MOAC nodes

./moac attach /xx/xxx/moac.ipc

Through HTTP-based rpc port connecting to local or remote MOAC nodes

./moac attach http://xxx.xxx.xxx.xxx:8545

Initiate MOAC testnet nodes and RPC service

./moac --testnet --rpc

Initiate MOAC testnet nodes which is nonlocally accessible; personal and debug services can also be nonlocally used while providing cross-domain resource sharing service.
