服务器评测
前言
接上一篇通过eosio_build.sh脚本安装EOS，其实EOS官方更推荐我们使用Docker来安装（EOS官方已经把编译好的镜像文件上传到Docker公共仓库中），简单快速，且不用趟编译过程中的各种依赖坑，所以在此墙裂推荐一下。
一、安装Docker
参见我的另一篇文章：在Ubuntu下安装Docker https://www.linuxidc.com/Linux/2018-09/154498.htm
二、安装EOS
通过Docker安装EOS，安装过程非常简单，只需要从官方拉取一个image即可，安装时间在10分钟不等。
1、拉取EOS官方Docker image
$ docker pull eosio/eos-dev
Using default tag: latest
latest: Pulling from eosio/eos-dev
a48c500ed24e: Pulling fs layer
1e1de00ff7e1: Pulling fs layer

Status: Downloaded newer image for eosio/eos-dev:latest
2、启动EOSIO节点
$ sudo docker run –rm –name eosio -d -p 8888:8888 -p 9876:9876 -v /tmp/work:/work -v /tmp/eosio/data:/mnt/dev/data -v /tmp/eosio/config:/mnt/dev/config eosio/eos-dev /bin/bash -c “nodeos -e -p eosio –plugin eosio::wallet_api_plugin –plugin eosio::wallet_plugin –plugin eosio::producer_plugin –plugin eosio::history_plugin –plugin eosio::chain_api_plugin –plugin eosio::history_api_plugin –plugin eosio::http_plugin -d /mnt/dev/data –config-dir /mnt/dev/config –http-server-address=0.0.0.0:8888 –access-control-allow-origin=* –contracts-console”
启动正常情况下，返回一个容器ID：
2e1a3574dd2908645843152e5d561af53f3ffa777a99d6ecdd152f5a91230f6f
三、验证节点通信
1、检查节点是否已经正常工作：
$ sudo docker logs –tail 10 eosio
正常情况下输出的内容应该类似于这样：

2、在浏览器中查看节点信息：
在浏览器地址栏访问 http://localhost:8888/v1/chain/get_info，检查RPC接口是否正常工作，正常情况下会显示：
{
“server_version”: “5875549c”,
“chain_id”: “cf057bbfb72640471fd910bcb67639c22df9f92470936cddc1ade0e2f2e7dc4f”,
“head_block_num”: 2233,
“last_irreversible_block_num”: 2232,
“last_irreversible_block_id”: “000008b872290cc75b8cb68b836a82ff87a1cc39b75f88341765f68bc925a623”,
“head_block_id”: “000008b9c9c9c11ee3e4c95613c971861788f7e80a82e20bcad0c2ef622aa7be”,
“head_block_time”: “2018-07-05T04:20:43.000”,
“head_block_producer”: “eosio”,
“virtual_block_cpu_limit”: 1861596,
“virtual_block_net_limit”: 9777935,
“block_cpu_limit”: 199900,
“block_net_limit”: 1048576
}
以上信息我们还可以通过cleos get info命令查看到。
至此，我们就在Docker容器中成功地运行了一个EOS节点区块链！
四、客户端配置
1、在docker下使用cleos客户端，我们需要以Docker的命令方式来运行，且需要带命令的完整路径
，如/opt/eosio/bin/cleos，为了后续操作方便，我们给cleos命令配置一下别名：
alias cleos=’docker exec eosio /opt/eosio/bin/cleos –wallet-url http://localhost:8888′
我们试着在终端测试一下是否生效：
$ cleos –help
看到命令的相关参数信息就说明已经可以运行生效了。
2、关闭节点运行
$ docker stop eosio
之前使用eosio_build.sh脚本的安装方式时，只能粗暴的按Ctrl+C中断节点，有了Docker后，就能优雅地关闭节点了。
