eos在linux上的配置並使用快照進行主網節點快速同步

前言

該eos的安裝並不是對源碼進行編譯，只是單純的在自己的服務器上搭建eos節點並同步主網數據的。所以如果您想要進行源碼編譯安裝eos，可能這篇博客對您的幫助不是很大。

在linux上安裝eos

我在虛擬機上安裝的是ubuntu18.04，並在root目錄下創建了一個eos目錄，以後的所有操作都會在這裏進行，接下來讓我們開始安裝吧:

1. 下載安裝包並進行安裝 :參考[https://github.com/EOSIO/eos/blob/master/README.md]，如果你之前安裝過eos，在安裝之前需要先卸載它。下面是幾個操作系統的安裝，後面v1.8.5可以更改下載源
   Ubuntu 18.04 Package 安裝（ 權限不夠前面加上sudo）

   $ wget https://github.com/eosio/eos/releases/download/v1.8.5/eosio_1.8.5-1-ubuntu-18.04_amd64.deb
   $ sudo apt install ./eosio_1.8.5-1-ubuntu-18.04_amd64.deb
   

   Ubuntu 16.04 Package 安裝

   $ wget https://github.com/eosio/eos/releases/download/v1.8.5/eosio_1.8.5-1-ubuntu-16.04_amd64.deb
   $ sudo apt install ./eosio_1.8.5-1-ubuntu-16.04_amd64.deb
   

   Ubuntu Package 卸載

   $ sudo apt remove eosio
   

   Mac OS X Brew 安裝

   $ brew tap eosio/eosio
   $ brew install eosio
   

   Mac OS X Brew 卸載

   $ brew remove eosio
   

   Centos RPM Package 安裝

   $ wget https://github.com/eosio/eos/releases/download/v1.8.5/eosio-1.8.5-1.el7.x86_64.rpm
   $ sudo yum install ./eosio-1.8.5-1.el7.x86_64.rpm
   

   Centos RPM Package 卸載

   $ sudo yum remove eosio
   

   安裝好之後，輸入nodeos -v 看看是否有沒有version，如圖則安裝成功
   

eos的啓動和簡單命令

1.可以參考大佬寫的博客裏面的詳細的介紹了eos和命令
2.genesis.json 該文件是連接到主網節點的文件，我已經將文件拷貝到/root/eos/ 下了，你可以在linux上創建一個文件重命名之後將下面內容拷貝進去，後續我們會用到他

{
  "initial_timestamp": "2018-06-08T08:08:08.888",
  "initial_key": "EOS7EarnUhcyYqmdnPon8rm7mBCTnBoot6o7fE2WzjvEX2TdggbL3",
  "initial_configuration": {
    "max_block_net_usage": 1048576,
    "target_block_net_usage_pct": 1000,
    "max_transaction_net_usage": 524288,
    "base_per_transaction_net_usage": 12,
    "net_usage_leeway": 500,
    "context_free_discount_net_usage_num": 20,
    "context_free_discount_net_usage_den": 100,
    "max_block_cpu_usage": 200000,
    "target_block_cpu_usage_pct": 1000,
    "max_transaction_cpu_usage": 150000,
    "min_transaction_cpu_usage": 100,
    "max_transaction_lifetime": 3600,
    "deferred_trx_expiration_window": 600,
    "max_transaction_delay": 3888000,
    "max_inline_action_size": 4096,
    "max_inline_action_depth": 4,
    "max_authority_depth": 6
  }
}

3.config.ini :該文件是一些nodeos的配置，文件位置 ,博客最下面會有詳細的文件配置，在這裏先不寫了，要不很佔位置，config.ini默認位置
linux: ~/.local/share/eosio/nodeos/config
mac os : ~/Library/Application Support/eosio/nodeos/config

4.nodeos 命令:這是啓動nodeos組件的命令 ，第一次啓動：

nodeos  --data-dir 區塊保存路徑  --genesis-json genesis.json路徑   --config-dir config.ini路徑   --delete-all-blocks

區塊保存路徑：你的區塊數據保存到哪裏，這個數據很大，需要很大的存儲空間
genesis.json路徑：可以配置genesis.json的位置，可以自定義位置，這個第一次啓動需要用
config.ini 路徑：可以定義config.ini的加載路徑，如果沒有--config-dir 則爲默認位置

啓動之後是如下圖片則是啓動成功了

然後 cleos get info 出現下面的狀態則已經接入主鏈
chain_id爲 aca376***** 則是主鏈

停止nodeos 必須用 pkill nodeos 否則會導致異常

用快照快速同步到當前主鏈的節點

1.前提：如果用快照的話 需要將 --data-dir 裏面的blocks、state目錄刪除
2.快照地址：https://eosnode.tools/snapshots
3.下載快照：wget $(wget --quiet "https://eosnode.tools/api/snapshots?limit=1" -O- | jq -r '.data[0].s3') -O snapshot.tar.gz
4.解壓快照：tar xvzf snapshot.tar.gz 快照保存在 當前目錄/snapshots/snapshots-****************.bin
5.同步快照： nodeos --snapshot 快照文件位置 --data-dir 區塊數據指定目錄 這樣就開始進行快照同步了，同步完成之後 cleos get info 可以看到從快照的區塊高度開始同步數據了
6.快照同步完之後，後面啓動nodeos 的話就不需要加 --snapshot 快照文件位置 這個參數了

啓動錢包組件

現在wallet組件和nodeos組件是分離的，如果想調用錢包的數據需要用下面的命令

keosd

ubuntu 沒有root權限的命令前面一律加上 sudo

寫在最後的疑問

現在我用快照同步區塊，當同步100W之後，發現同步越來越慢，希望大佬們看到我的問題能夠留言，謝謝！
