拿了一个GitHub的go采集namenode指标的项目，修改了一下，本地调测正常，记录一下在Linux环境编译并运行的过程。
1.安装go环境
[root@hadoop1011 ~]# yum install go -y Loaded plugins: fastestmirror, langpacks Loading mirror speeds from cached hostfile Resolving Dependencies --> Running transaction check ---> Package golang.x86_64 0:1.18.9-1.el7 will be installed --> Processing Dependency: golang-bin = 1.18.9-1.el7 for package: golang-1.18.9-1.el7.x86_64 --> Processing Dependency: golang-src = 1.18.9-1.el7 for package: golang-1.18.9-1.el7.x86_64 --> Running transaction check ---> Package golang-bin.x86_64 0:1.18.9-1.el7 will be installed ---> Package golang-src.noarch 0:1.18.9-1.el7 will be installed --> Finished Dependency Resolution Dependencies Resolved ================================================================================================================================================================================================= Package Arch Version Repository Size ================================================================================================================================================================================================= Installing: golang x86_64 1.18.9-1.el7 epel 685 k Installing for dependencies: golang-bin x86_64 1.18.9-1.el7 epel 105 M golang-src noarch 1.18.9-1.el7 epel 9.1 M Transaction Summary ================================================================================================================================================================================================= Install 1 Package (+2 Dependent packages) Total download size: 115 M Installed size: 420 M Is this ok [y/d/N]: y Downloading packages: (1/3): golang-1.18.9-1.el7.x86_64.rpm | 685 kB 00:00:00 (2/3): golang-src-1.18.9-1.el7.noarch.rpm | 9.1 MB 00:00:02 (3/3): golang-bin-1.18.9-1.el7.x86_64.rpm | 105 MB 00:00:14 ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- Total 8.2 MB/s | 115 MB 00:00:14 Running transaction check Running transaction test Transaction test succeeded Running transaction Installing : golang-src-1.18.9-1.el7.noarch 1/3 Installing : golang-1.18.9-1.el7.x86_64 2/3 Installing : golang-bin-1.18.9-1.el7.x86_64 3/3 Verifying : golang-bin-1.18.9-1.el7.x86_64 1/3 Verifying : golang-1.18.9-1.el7.x86_64 2/3 Verifying : golang-src-1.18.9-1.el7.noarch 3/3 Installed: golang.x86_64 0:1.18.9-1.el7 Dependency Installed: golang-bin.x86_64 0:1.18.9-1.el7 golang-src.noarch 0:1.18.9-1.el7 Complete!
2.尝试编译，发现失败
[root@hadoop1011 ~]# go build namenode_exporter.go namenode_exporter.go:9:2: no required module provides package github.com/prometheus/client_golang/prometheus: go.mod file not found in current directory or any parent directory; see 'go help mo dules'namenode_exporter.go:10:2: no required module provides package github.com/prometheus/log: go.mod file not found in current directory or any parent directory; see 'go help modules'
3. 更改GOPROXY依赖下载代理为国内的地址
[root@hadoop1011 ~]# go env GO111MODULE="" GOARCH="amd64" GOBIN="" GOCACHE="/root/.cache/go-build" GOENV="/root/.config/go/env" GOEXE="" GOEXPERIMENT="" GOFLAGS="" GOHOSTARCH="amd64" GOHOSTOS="linux" GOINSECURE="" GOMODCACHE="/root/go/pkg/mod" GONOPROXY="" GONOSUMDB="" GOOS="linux" GOPATH="/root/go" GOPRIVATE="" GOPROXY="https://proxy.golang.org,direct" GOROOT="/usr/lib/golang" GOSUMDB="sum.golang.org" GOTMPDIR="" GOTOOLDIR="/usr/lib/golang/pkg/tool/linux_amd64" GOVCS="" GOVERSION="go1.18.9" GCCGO="gccgo" GOAMD64="v1" AR="ar" CC="gcc" CXX="g++" CGO_ENABLED="1" GOMOD="/dev/null" GOWORK="" CGO_CFLAGS="-g -O2" CGO_CPPFLAGS="" CGO_CXXFLAGS="-g -O2" CGO_FFLAGS="-g -O2" CGO_LDFLAGS="-g -O2" PKG_CONFIG="pkg-config" GOGCCFLAGS="-fPIC -m64 -pthread -fmessage-length=0 -fdebug-prefix-map=/tmp/go-build820474747=/tmp/go-build -gno-record-gcc-switches" [root@hadoop1011 go_pkg]# go env -w GOPROXY=https://mirrors.aliyun.com/goproxy,direct
4.编译项目
[root@hadoop1011 go_pkg]# go build namenode_exporter.go go: downloading github.com/prometheus/log v0.0.0-20151026012452-9a3136781e1f go: downloading github.com/prometheus/client_golang v0.8.0 go: downloading github.com/Sirupsen/logrus v1.0.6 go: downloading github.com/prometheus/procfs v0.0.0-20180725123919-05ee40e3a273 go: downloading github.com/golang/protobuf v1.2.0 go: downloading github.com/prometheus/common v0.0.0-20180801064454-c7de2306084e go: downloading github.com/beorn7/perks v0.0.0-20180321164747-3a771d992973 go: downloading github.com/prometheus/client_model v0.0.0-20180712105110-5c3871d89910 go: downloading golang.org/x/sys v0.0.0-20220715151400-c0bba94af5f8 go: downloading golang.org/x/crypto v0.0.0-20180910181607-0e37d006457b go: downloading github.com/matttproud/golang_protobuf_extensions v1.0.1 [root@hadoop1011 go_pkg]# ls go.mod go.sum LICENSE namenode_exporter namenode_exporter.exe namenode_exporter.go README.md resourcemanager_exporter.go [root@hadoop1011 go_pkg]# ll total 20936 -rw-r--r-- 1 root root 1033 Apr 19 19:43 go.mod -rw-r--r-- 1 root root 4526 Apr 19 19:43 go.sum -rw-r--r-- 1 root root 11357 Apr 19 19:43 LICENSE -rwxr-xr-x 1 root root 10570414 Apr 19 19:56 namenode_exporter -rw-r--r-- 1 root root 10808832 Apr 19 19:30 namenode_exporter.exe -rw-r--r-- 1 root root 13704 Apr 19 19:43 namenode_exporter.go -rw-r--r-- 1 root root 944 Apr 19 19:43 README.md -rw-r--r-- 1 root root 9586 Apr 19 19:43 resourcemanager_exporter.go
5.启动进程
[root@hadoop1011 go_pkg]# nohup ./namenode_exporter & [1] 4361 [root@hadoop1011 go_pkg]# nohup: ignoring input and appending output to ‘nohup.out' [root@hadoop1011 go_pkg]# ll total 20940 -rw-r--r-- 1 root root 1033 Apr 19 19:43 go.mod -rw-r--r-- 1 root root 4526 Apr 19 19:43 go.sum -rw-r--r-- 1 root root 11357 Apr 19 19:43 LICENSE -rwxr-xr-x 1 root root 10570414 Apr 19 19:56 namenode_exporter -rw-r--r-- 1 root root 10808832 Apr 19 19:30 namenode_exporter.exe -rw-r--r-- 1 root root 13704 Apr 19 19:43 namenode_exporter.go -rw------- 1 root root 108 Apr 19 19:56 nohup.out -rw-r--r-- 1 root root 944 Apr 19 19:43 README.md -rw-r--r-- 1 root root 9586 Apr 19 19:43 resourcemanager_exporter.go [root@hadoop1011 go_pkg]# cat nohup.out time="2023-04-19T19:56:22+08:00" level=info msg="Starting Server: :9070" file=namenode_exporter.go line=395 [root@hadoop1011 go_pkg]# ll total 20940 -rw-r--r-- 1 root root 1033 Apr 19 19:43 go.mod -rw-r--r-- 1 root root 4526 Apr 19 19:43 go.sum -rw-r--r-- 1 root root 11357 Apr 19 19:43 LICENSE -rwxr-xr-x 1 root root 10570414 Apr 19 19:56 namenode_exporter -rw-r--r-- 1 root root 10808832 Apr 19 19:30 namenode_exporter.exe -rw-r--r-- 1 root root 13704 Apr 19 19:43 namenode_exporter.go -rw------- 1 root root 108 Apr 19 19:56 nohup.out -rw-r--r-- 1 root root 944 Apr 19 19:43 README.md -rw-r--r-- 1 root root 9586 Apr 19 19:43 resourcemanager_exporter.go
6.检测进程是否存在
[root@hadoop1011 go_pkg]# ss -tlnp|grep 9070
LISTEN 0 128 :::9070 :::* users:(("namenode_export",pid=4361,fd=3))
[root@hadoop1011 go_pkg]# 总结
