#EOS編譯安裝

#環境 ubuntu 16.4 
# EOS安裝部
# 以下代碼保存為install.eos.sh文件
# 執行 sudo bash install.eos.sh

#!/bin/bash
#install.eos.sh
# By Elven,2018-11-9
#EOS 安裝

#從github克隆主網代碼
cd /opt
git clone https://github.com/EOS-Mainnet/eos.git --recursive

#查看mainnet ，切換最新版本
cd /opt/eos
git tag
git tag |grep mainnet |tail -n 1
git checkout `git tag |grep mainnet |tail -n 1`
git branch

#更新子模塊
git submodule update --init --recursive

#查詢得shell腳本里的MongoDB下載地址失效，修改如下
sed -i 's#https://fastdl.mongodb.org#http://downloads.mongodb.org#'  scripts/*.sh

#運行編譯
./eosio_build.sh -s "EOS"

#編譯完成后，安裝
./eosio_install.sh

#eos加入主網並啟動

#下載節點配置
#主要用到genesis.json和config.ini
#主網創世區塊文件genesis.json
#默認配置config.ini

#download and  Configuring
mkdir /opt/EOSmainNet
cd /opt/EOSmainNet
git clone https://github.com/CryptoLions/EOS-MainNet.git ./ 
chmod +x ./*.sh   
chmod +x ./Wallet/*.sh 

#設置當前用戶ubuntu權限(可選)
sudo chown ubuntu:ubuntu -R /opt/EOSmainNet

#修改區塊儲存限制(已超過默認存儲大小)
sudo sed -i 's/chain-state-db-size-mb =.*/chain-state-db-size-mb = 1024000/'  /opt/EOSmainNet/config.ini

#更換nodeos編譯路徑
sudo sed -i 's#/home/eos-sources/eos#/opt/eos#' *.sh

#首次啟動,清除現有區塊並加入主網
sudo /opt/EOSmainNet/start.sh --genesis-json /opt/EOSmainNet/genesis.json --delete-all-blocks

#再次啟動，不需指定genesis.json
sudo /opt/EOSmainNet/start.sh
 #關閉 sudo /opt/EOSmainNet/stop.sh

#基本查詢

#查看區塊同步
sudo /opt/EOSmainNet/cleos.sh get info

#查看區塊高度
/opt/EOSmainNet/cleos.sh get info |awk -F'[ |,]' '/head_block_num/{print $4}'

#curl 訪問rpc api查看區塊
#sudo apt install jq #格式化josn文件
#查看區塊同步
[ -f /usr/bin/jq ] || { sudo apt updata;sudo apt install jq; }
curl -s  http://127.0.0.1:8888/v1/chain/get_info |jq

#獲取區塊高度
curl -s  http://localhost:8888/v1/chain/get_info |awk -F'[,:]*' '{print $6}'

#查看日志
tailf /opt/EOSmainNet/stderr.txt

nodeos進程異常關閉，再次啟動要區塊回放--replay-blockchain很耗時間
eos不適合docker方式部署，eosio/eos鏡像停止維護
通過備份文件重放區塊中信息,區塊超過3千萬后區塊回放很慢，不如直接同步
區塊備份文件下載(個人實測后不推薦) https://eosnode.tools/blocks

為加快同步速度，添加一些物理距離近的同步節點
當前的網絡p2p-peer-address 地址可以從下面地址獲得
https://eosnodes.privex.io/?config=1

#同步節點p2p-peer-address不可用時，會一直報錯，最好注釋掉

#var
EosLog=/opt/EOSmainNet/stderr.txt
Config=/opt/EOSmainNet/config.ini

# 注釋掉不可用的 p2p-peer-address
#Connection refused
List=`awk -F '[ :]*' '/Connection refused/{print $(NF-3)}'  $EosLog |sort -u`
for N in $List; do sed -i "s/^p2p-peer.*${N}/#&/"  $Config ; done
#Host not found
List=`awk -F '[ :]*' '/Host not found/{print $(NF-5)}'  $EosLog |sort -u`
for N in $List; do sed -i "s/^p2p-peer.*${N}/#&/"  $Config ; done

# 重啟EOS
