本文讲述在ubuntu16.04虚拟机下面安装最新的eos的过程，感觉比以太坊要复杂一些。eos现在只能从源代码编译安装，而不能用apt-get的方式进行安装。需要注意的一点是需要修改内存限制。默认的最低内存是7G，虚拟机只分配了5G内存。
1 用git下载eos源代码
git clone https://github.com/EOSIO/eos --recursive2 修改内存限制
打开eos/scripts/eosio_build_ubuntu.sh，有这句话
if [ "${MEM_MEG}" -lt 7000 ]; then
这句里面的7000改成4000。
OS_VER=$( grep VERSION_ID /etc/os-release | cut -d'=' -f2 | sed 's/[^0-9\.]//gI' )
OS_MAJ=$(echo "${OS_VER}" | cut -d'.' -f1)
OS_MIN=$(echo "${OS_VER}" | cut -d'.' -f2)
MEM_MEG=$( free -m | sed -n 2p | tr -s ' ' | cut -d\ -f2 || cut -d' ' -f2 )
CPU_SPEED=$( lscpu | grep -m1 "MHz" | tr -s ' ' | cut -d\ -f3 || cut -d' ' -f3 | cut -d'.' -f1 )
CPU_CORE=$( lscpu | grep "^CPU(s)" | tr -s ' ' | cut -d\ -f2 || cut -d' ' -f2 )
MEM_GIG=$(( ((MEM_MEG / 1000) / 2) ))
JOBS=$(( MEM_GIG > CPU_CORE ? CPU_CORE : MEM_GIG ))
DISK_INSTALL=$(df -h . | tail -1 | tr -s ' ' | cut -d\ -f1 || cut -d' ' -f1)
DISK_TOTAL_KB=$(df . | tail -1 | awk '{print $2}')
DISK_AVAIL_KB=$(df . | tail -1 | awk '{print $4}')
DISK_TOTAL=$(( DISK_TOTAL_KB / 1048576 ))
DISK_AVAIL=$(( DISK_AVAIL_KB / 1048576 ))
printf "\\n\\tOS name: %s\\n" "${OS_NAME}"
printf "\\tOS Version: %s\\n" "${OS_VER}"
printf "\\tCPU speed: %sMhz\\n" "${CPU_SPEED}"
printf "\\tCPU cores: %s\\n" "${CPU_CORE}"
printf "\\tPhysical Memory: %s Mgb\\n" "${MEM_MEG}"
printf "\\tDisk install: %s\\n" "${DISK_INSTALL}"
printf "\\tDisk space total: %sG\\n" "${DISK_TOTAL%.*}"
printf "\\tDisk space available: %sG\\n" "${DISK_AVAIL%.*}"
if [ "${MEM_MEG}" -lt 7000 ]; then
printf "\\tYour system must have 7 or more Gigabytes of physical memory installed.\\n"
printf "\\tExiting now.\\n"
exit 1
fi
case "${OS_NAME}" in3 执行eos目录下的编译脚本eosio_build.sh
~/eos$ sudo ./eosio_build.sh
这个过程会下载大量的依赖库，用时要俩个小时左右。成功后会显示界面：

EOS.IO has been successfully built. 0:32:57
To verify your installation run the following commands:
/home/liuwenbin/opt/mongodb/bin/mongod -f /home/liuwenbin/opt/mongodb/mongod.conf &
cd /home/liuwenbin/eos/build; make test
For more information:
EOS.IO website: https://eos.io
EOS.IO Telegram channel @ https://t.me/EOSProject
EOS.IO resources: https://eos.io/resources/
EOS.IO wiki: https://github.com/EOSIO/eos/wiki4 执行安装
进入build目录，执行下面命令
~/eos/build$ sudo make install
安装完成后会在 /usr/local/eosio/bin下生成 cleos、kesod、nodeos等可执行文件。
/usr/local/eosio/bin$ ls
cleos eosio-abigen eosiocpp eosio-launcher eosio-s2wasm eosio-wast2wasm keosd nodeos5 设置PATH路径
上面步骤会在 /usr/local下面生成 eosio 文件夹。打开 /etc/profile 文件，添加 ./usr/local/eosio/bin 目录到PATH变量中
export PATH=/usr/local/eosio/bin:$PATH6 启动nodeos节点
首先准备一个genesis.json，文件就保存在eos目录下，文件内容我用的是：
{
"initial_timestamp": "2018-03-01T12:00:00.000",
"initial_key": "EOS6MRyAjQq8ud7hVNYcfnVPJqcVpscN5So8BhtHuGYqET5GDW5CV",
"initial_configuration": {
"base_per_transaction_net_usage": 100,
"base_per_transaction_cpu_usage": 500,
"base_per_action_cpu_usage": 1000,
"base_setcode_cpu_usage": 2097152,
"per_signature_cpu_usage": 100000,
"per_lock_net_usage": 32,
"context_free_discount_cpu_usage_num": 20,
"context_free_discount_cpu_usage_den": 100,
"max_transaction_cpu_usage": 10485760,
"max_transaction_net_usage": 104857,
"max_block_cpu_usage": 104857600,
"target_block_cpu_usage_pct": 1000,
"max_block_net_usage": 1048576,
"target_block_net_usage_pct": 1000,
"max_transaction_lifetime": 3600,
"max_transaction_exec_time": 0,
"max_authority_depth": 6,
"max_inline_depth": 4,
"max_inline_action_size": 4096,
"max_generated_transaction_count": 16
},
"initial_chain_id": "0000000000000000000000000000000000000000000000000000000000000000"
}
然后执行命令启动nodeos节点：
nodeos -e -p eosio --plugin eosio::wallet_api_plugin --plugin eosio::chain_api_plugin --plugin eosio::history_api_plugin --genesis-json genesis.json运行界面如下：
可以看到这个节点在不停的产生区块，周期是0.5s左右。
区块数据保存在目录 ~/.local/share/eosio/nodeos/data下面。
只有第一次启动时需要用--genesis-json选项，以后启动时不要再带这个选项，否则会报错。
7 通过config.ini文件来启动节点
除了上面的用命令行来出块的方式，还可以通过配置config.ini文件的方式来启动nodeos节点。新建一个文件夹，创建一个genesis.json，内容和上节的一样。然后再创建一个config.ini文件，文件内容如下：
genesis-json = genesis.json
block-log-dir = blocks
readonly = 0
send-whole-blocks = true
shared-file-dir = blockchain
shared-file-size = 8192
unlock-timeout = 90000
bnet-endpoint = 0.0.0.0:4321
http-server-address = 0.0.0.0:8888
p2p-listen-endpoint = 0.0.0.0:9876
p2p-server-address = localhost:9876
allowed-connection = any
#p2p-peer-address = localhost:9877
required-participation = true
signature-provider = EOS6MRyAjQq8ud7hVNYcfnVPJqcVpscN5So8BhtHuGYqET5GDW5CV=KEY:5KQwrPbwdL6PhXujxW37FSSQZ1JiwsST4cqQzDeyXtP79zkvFD3
producer-name = eosio
plugin = eosio::producer_plugin
plugin = eosio::chain_api_plugin
plugin = eosio::history_api_plugin
plugin = eosio::wallet_api_plugin
plugin = eosio::http_plugin
enable-stale-production = true基本上命令行中可用的命令，都可以去掉前缀的--后然后直接用到config.ini中。比如命令行中的 -e，对应配置文件中的
enable-stale-production = true，即允许出块；命令行中的 -p eosio，在配置文件里可以写成 producer-name = eosio；命令行中的--plugin eosio::wallet_api_plugin --plugin eosio::chain_api_plugin --plugin eosio::history_api_plugin，在配置文件中可以写成：
plugin = eosio::chain_api_plugin
plugin = eosio::history_api_plugin
plugin = eosio::wallet_api_plugin此外配置文件还可以配置
创建好genesis.json和config.ini后的文件夹：
~/eostest1$ ls
config.ini genesis.json然后启动nodeos节点：
~/eostest1$ sudo nodeos --data-dir ./ --config-dir ./节点启动起来了：
~/eostest1$ sudo nodeos --data-dir ./ --config-dir ./
