目前，EOS主网已经成功启动，在投票率达到15%之后，主网功能被激活，下面教大家如何连接EOS主网。
一、从GitHub上克隆主网代码仓库：（注意EOS-Mainnet/eos 与 EOSIO/eos 的版本是一致的。若以前在本地已经安装编译过EOSIO/eos的1.0.2版本及以上，则可以直接跳到步骤三）
git clone https://github.com/EOS-Mainnet/eos
cd eos
git submodule update --init --recursive
git tag
git checkout mainnet-1.0.2.2
二、编译eos代码
./eosio_build.sh
三、替换config.ini 和 genesis.json 文件
（1）运行nodeos节点后会生成默认的config.ini/genesis.json文件，现在对其进行替换
（2）在不同系统中找到其文件地址：
- linux-ubuntu: ~/.local/share/eosio/nodeos/config/
- mac-osx: ~/Library/Application\ Support/eosio/nodeos/config/
（3）新的config.ini文件设置如下：
# fullnode sample config
blocks-dir = "blocks"
chain-state-db-size-mb = 1024
reversible-blocks-db-size-mb = 340
contracts-console = false
https-client-validate-peers = 1
http-server-address = 0.0.0.0:8888
access-control-allow-credentials = false
p2p-listen-endpoint = 0.0.0.0:9876
p2p-server-address = 0.0.0.0:9876
# List of peers
p2p-peer-address = p2p.one.eosdublin.io:9876
p2p-peer-address = eu-west-nl.eosamsterdam.net:9876
p2p-peer-address = p2p.mainnet.eosgermany.online:9876
p2p-peer-address = 35.197.190.234:19878
p2p-peer-address = p2p.genereos.io:9876
p2p-peer-address = fullnode.eoslaomao.com:443
p2p-peer-address = new.eoshenzhen.io:10034
p2p-peer-address = node1.eosphere.io:9876
p2p-peer-address = p2p.meet.one:9876
p2p-peer-address = bp.eosbeijing.one:8080
p2p-peer-address = peer1.mainnet.helloeos.com.cn:80
p2p-peer-address = p2p-public.hkeos.com:19875
p2p-peer-address = pub1.eostheworld.io:9876
p2p-peer-address = eu1.eosdac.io:49876
p2p-peer-address = peer.eosio.sg:9876
p2p-max-nodes-per-host = 10
agent-name = "eosmainnet"
# allowed-connection can be set to "specified" to use whitelisting with the "peer-key" option
allowed-connection = any
# peer-private-key is needed if you are whitelisting specific peers with the "peer-key" option
peer-private-key = ["EOS6qTvpRYx35aLonqUkWAMwAf3mFVugYfQCbjV67zw2aoe7Vx7qd", "5JroNC1B4pz9gJzNZeU7tkU6YMtoeWRCr4CJJwKsVXnJhRbKXSC"]
max-clients = 250
connection-cleanup-period = 30
network-version-match = 1
sync-fetch-span = 100
max-implicit-request = 1500
enable-stale-production = false
pause-on-startup = false
max-transaction-time = 10000
max-irreversible-block-age = -1
txn-reference-block-lag = 0
# Plugins used for full nodes
plugin = eosio::chain_api_plugin
plugin = eosio::history_api_plugin
plugin = eosio::chain_plugin
plugin = eosio::history_plugin
plugin = eosio::net_plugin
plugin = eosio::net_api_plugin
其中p2p-peer-address的配置来源于：

（4）genesis.json文件内容如下：
{
"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
}
}
此文件称为创世json文件，来自以下链接：
https://github.com/EOS-Mainnet/eos/blob/launch-rc-1.0.2/mainnet-genesis.json
四、将以上的创世json文件，复制拷贝到~/eos/build/program/nodeos目录下，并启动nodeos节点：
./nodeos --genesis-json genesis.json
可以看到node已经连上主网，on_incoming_block就代表正在同步区块内容了。不过有的节点地址会出现连接不上的error。可以尝试在上述的google链接地址中的表格选择稳定的peer节点进行设置。

五、查看链信息:
比对chain_id是否为：aca376f206b8fc25a6ed44dbdc66547c36c6c33e3a119ffbeaef943642f0e906
运行cleos命令：
cleos get info
返回信息为:
{
"server_version": "26ec83de",
"chain_id": "aca376f206b8fc25a6ed44dbdc66547c36c6c33e3a119ffbeaef943642f0e906",
"head_block_num": 493299,
"last_irreversible_block_num": 493298,
"last_irreversible_block_id": "000786f240401f6fcc24de5240ddd9fead88cbbbbec740c181258dc3e682fb96",
"head_block_id": "000786f36fafd9e98d703a004a302e86958de991dedbbc27f33c393c2adb2c6f",
"head_block_time": "2018-06-13T07:28:58",
"head_block_producer": "genesisblock",
"virtual_block_cpu_limit": 200000000,
"virtual_block_net_limit": 1048576000,
"block_cpu_limit": 199900,
"block_net_limit": 1048576
}
六、查看区块数据
在数据正常同步后，使用cleos命令可以查看一些区块信息：譬如查看区块191的数据
cleos get block 191
返回信息如下，可以看到transaction内容
