准备工作
如果你想在本地或者服务器上运行跨链网关，你需要在机器上安装有以下的依赖：
安装和配置
执行下面的命令进行编译sidecar
export CGO_ENABLED=1 //开启CGO编译功能，sidecar中依赖库会用到c语言库
git clone https://gitlab.33.cn/link33/sidecar
cd sidecar
make prepare
make - centos环境中编译可能会出现如下错误
# github.com/herumi/bls-eth-go-binary/bls
/usr/bin/ld: cannot find -lstdc++
collect2: error: ld returned 1 exit status
make: *** [build] Error 2- 解决办法如下，先查询是否有相应的c++库
find / -name *tdc*
cp /usr/lib64/libstdc++.so.6 /usr/lib/libstdc++.so
- centos 中还会缺少glibc-2.18库，需要安装一下
下载文件
wget https://mirrors.tuna.tsinghua.edu.cn/gnu/glibc/glibc-2.18.tar.gz
解压
tar -xvf glibc-2.18.tar.gz
创建编译目录
cd glibc-2.18
mkdir build
编译、安装
cd build/
../configure --prefix=/usr --disable-profile --enable-add-ons --with-headers=/usr/include --with-binutils=/usr/bin
make -j 8
make install
创建工作文件sidecar
mkdir -p $HOME/sidecar/plugins
// 将上面编译好的可执行文件放入创建的文件夹下
mv bin/sidecar $HOME/sidecar/fabric插件环境配置
chain33插件环境配置
跨链网关配置
sidecar想要完成运行起来需要配置中继链和应用链的相关信息，可以指定配置目录，默认路径为 $HOME/sidecar 也可以导入环境变量:
export SIDECAR_PATH=$HOME/sidecar # 默认路径
or
export SIDECAR_PATH=/home/harry/distribute_sidecar/sidecar01/ #指定的配置目录初始化网关节点
./sidecar init repo=$SIDECAR_PATH
成功初始化后，系统会自动生成如下目录文件:
harry@harry-VirtualBox:~/sidecar$ ls -l

-rw-r--r-- 1 harry harry 250 12月 15 10:39 authz_model.conf
-rw-r--r-- 1 harry harry 220 12月 15 10:39 authz_policy.csv

-rwxrwxr-x 1 harry harry 38531376 12月 15 10:37 sidecar
-rw-r--r-- 1 harry harry 970 12月 15 10:39 sidecar.toml获取网关节点ID
./sidecar p2p id正确会显示如下:
harry@harry-VirtualBox:~/sidecar$ ./sidecar p2p id

修改sidecar.toml文件配置
单节点网关下同时运行fabric和chain33插件配置示例:
RepoRoot = "/home/harry/distribute_sidecar/sidecar01/"
title = "Sidecar"
[port]
http = 44744
pprof = 44755
[log]
dir = "logs"
filename = "sidecar.log"
ReportCaller = false
level = "info"
[log.module]
api_server = "info"
appchain_mgr = "info"
App = "info"
exchanger = "info"
executor = "info"
monitor = "info"
peer_mgr = "info"
router = "info"
swarm = "info"
syncer = "info"
manager = "info"
rule = "info"
[[appchains]]
enable = true
type = "appchain"
did = "link33:chain33:local&broker"
config = "chain33"
plugin = "chain33-client"
[[appchains]]
enable = true
type = "appchain"
did = "link33:fabric:mychannel&data_swapper"
plugin = "fabric-client-1.4"
config = "fabric"
[security]
EnableTLS = false
tlsca = ""
CommonName = ""
[peer]
# peer地址使用上面获取的p2p节点地址
peers = ["/ip4/127.0.0.1/tcp/4000/p2p/QmXtgbubrdPQHoiXSTibb4xvTL4QVPykuKW73HZcdH9f7k"]
connectors = ["localhost:60011"]
providers = 1
启动跨链网关sidecar
./sidecar start repo=$SIDECAR_PATH
