1. 安装nodejs
2. brew tap ethereum/ethereum
3. brew install ethereum
4. Ethereum Wallet and Mist Beta 0.10.0

1. 文件名：CustomGenesis.json

geth --identity "mydev" --rpc --rpccorsdomain "*" --datadir "./Mychains/dev" --rpcapi "db,eth,net,web3" init "./CustomGenesis.json"

1. 只开启rpc
   geth --datadir "./Mychains/dev" --identity "mydev" --rpccorsdomain "*" --networkid 99 console
   
2. 开启rpc和http
   geth --datadir "./Mychains/dev" --identity "mydev" --rpc --rpcapi "db,eth,net,web3,personal,web3" --nodiscover --rpccorsdomain "*" --networkid 100 console
   

geth attach /Users/uiste/www/blockchain/test-geth/Mychains/dev/geth.ipc

如果是Web应用的时候，就使用http://127.0.0.8545 地址就是连接

Mac遇到启动mist失败

解决方案：

1. 通过命令行方式启动让Ethereum Wallet，添加参数让他和刚起的私有链同用一个ipc。

   uiste@uiste:~/www/blockchain/test-geth/Mychains/dev$     cd /Applications/
   uiste@uiste:/Applications$     ./Ethereum\ Wallet.app/Contents/MacOS/Ethereum\ Wallet --rpc "/Users/uiste/www/blockchain/test-geth/Mychains/dev/geth.ipc"

2. 通过命令行方式启动Mist，添加参数让他和刚起的私有链同用一个ipc。
   

   uiste@uiste:/Applications$      Mist.app/Contents/MacOS/Mist --rpc "/Users/uiste/www/blockchain/test-geth/Mychains/dev/geth.ipc"

启动Mist后的界面如下：

停止挖矿，命令行查看账户余额
