eos在linux上的配置并使用快照进行主网节点快速同步
前言
该eos的安装并不是对源码进行编译，只是单纯的在自己的服务器上搭建eos节点并同步主网数据的。所以如果您想要进行源码编译安装eos，可能这篇博客对您的帮助不是很大。
在linux上安装eos
我在虚拟机上安装的是ubuntu18.04，并在root目录下创建了一个eos目录，以后的所有操作都会在这里进行，接下来让我们开始安装吧:
-
下载安装包并进行安装 :参考[https://github.com/EOSIO/eos/blob/master/README.md]，如果你之前安装过eos，在安装之前需要先卸载它。下面是几个操作系统的安装，后面v1.8.5可以更改下载源
Ubuntu 18.04 Package 安装（ 权限不够前面加上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.debUbuntu 16.04 Package 安装
$ 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.debUbuntu Package 卸载
$ sudo apt remove eosioMac OS X Brew 安装
$ brew tap eosio/eosio $ brew install eosioMac OS X Brew 卸载
$ brew remove eosioCentos RPM Package 安装
$ 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.rpmCentos RPM Package 卸载
$ sudo yum remove eosio安装好之后，输入
nodeos -v看看是否有没有version，如图则安装成功
![在这里插入图片描述]()
eos的启动和简单命令
1.可以参考大佬写的博客里面的详细的介绍了eos和命令
2.genesis.json 该文件是连接到主网节点的文件，我已经将文件拷贝到/root/eos/ 下了，你可以在linux上创建一个文件重命名之后将下面内容拷贝进去，后续我们会用到他
{
"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 :该文件是一些nodeos的配置，文件位置 ,博客最下面会有详细的文件配置，在这里先不写了，要不很占位置，config.ini默认位置
linux: ~/.local/share/eosio/nodeos/config
mac os : ~/Library/Application Support/eosio/nodeos/config
4.nodeos 命令:这是启动nodeos组件的命令 ，第一次启动：
nodeos --data-dir 区块保存路径 --genesis-json genesis.json路径 --config-dir config.ini路径 --delete-all-blocks
区块保存路径：你的区块数据保存到哪里，这个数据很大，需要很大的存储空间
genesis.json路径：可以配置genesis.json的位置，可以自定义位置，这个第一次启动需要用
config.ini 路径：可以定义config.ini的加载路径，如果没有--config-dir 则为默认位置
启动之后是如下图片则是启动成功了
然后 cleos get info 出现下面的状态则已经接入主链
chain_id为 aca376***** 则是主链
停止nodeos 必须用 pkill nodeos 否则会导致异常
用快照快速同步到当前主链的节点
1.前提：如果用快照的话 需要将 --data-dir 里面的blocks、state目录删除
2.快照地址：https://eosnode.tools/snapshots
3.下载快照：wget $(wget --quiet "https://eosnode.tools/api/snapshots?limit=1" -O- | jq -r '.data[0].s3') -O snapshot.tar.gz
4.解压快照：tar xvzf snapshot.tar.gz 快照保存在 当前目录/snapshots/snapshots-****************.bin
5.同步快照： nodeos --snapshot 快照文件位置 --data-dir 区块数据指定目录 这样就开始进行快照同步了，同步完成之后 cleos get info 可以看到从快照的区块高度开始同步数据了
6.快照同步完之后，后面启动nodeos 的话就不需要加 --snapshot 快照文件位置 这个参数了
启动钱包组件
现在wallet组件和nodeos组件是分离的，如果想调用钱包的数据需要用下面的命令
keosd
ubuntu 没有root权限的命令前面一律加上 sudo
写在最后的疑问
现在我用快照同步区块，当同步100W之后，发现同步越来越慢，希望大佬们看到我的问题能够留言，谢谢！
