# 线上日志查询工具
|
||
|
||
## 编译和打包
|
||
|
||
Rust 工具是单文件实现，不依赖 Cargo 包：
|
||
|
||
```bash
|
||
rustc scripts/ops/search-worker-logs.rs -O -o /tmp/jh-logq
|
||
```
|
||
|
||
上面命令只编译当前机器可运行的版本。本机是 macOS 时，不能把这个默认产物直接放到 Linux 服务器。
|
||
|
||
打 Linux x86_64 服务器包：
|
||
|
||
```bash
|
||
mkdir -p dist
|
||
rustup target add x86_64-unknown-linux-musl
|
||
HOST_TRIPLE="$(rustc -vV | awk '/^host:/ {print $2}')"
|
||
RUST_LLD="$(rustc --print sysroot)/lib/rustlib/${HOST_TRIPLE}/bin/rust-lld"
|
||
rustc --target x86_64-unknown-linux-musl \
|
||
-C linker="$RUST_LLD" \
|
||
scripts/ops/search-worker-logs.rs \
|
||
-O \
|
||
-o dist/jh-logq-linux-amd64
|
||
tar -czf dist/jh-logq-linux-amd64.tar.gz -C dist jh-logq-linux-amd64
|
||
```
|
||
|
||
如果服务器是 ARM64：
|
||
|
||
```bash
|
||
mkdir -p dist
|
||
rustup target add aarch64-unknown-linux-musl
|
||
HOST_TRIPLE="$(rustc -vV | awk '/^host:/ {print $2}')"
|
||
RUST_LLD="$(rustc --print sysroot)/lib/rustlib/${HOST_TRIPLE}/bin/rust-lld"
|
||
rustc --target aarch64-unknown-linux-musl \
|
||
-C linker="$RUST_LLD" \
|
||
scripts/ops/search-worker-logs.rs \
|
||
-O \
|
||
-o dist/jh-logq-linux-arm64
|
||
tar -czf dist/jh-logq-linux-arm64.tar.gz -C dist jh-logq-linux-arm64
|
||
```
|
||
|
||
上传并安装到服务器：
|
||
|
||
```bash
|
||
scp dist/jh-logq-linux-amd64.tar.gz user@server:/tmp/
|
||
ssh user@server
|
||
cd /tmp
|
||
tar -xzf jh-logq-linux-amd64.tar.gz
|
||
sudo install -m 0755 jh-logq-linux-amd64 /usr/local/bin/jh-logq
|
||
jh-logq --help
|
||
```
|
||
|
||
如果交叉编译仍报 linker 相关错误，用 Docker 编译 Linux 产物兜底：
|
||
|
||
```bash
|
||
mkdir -p dist
|
||
docker run --rm -v "$PWD":/work -w /work rust:1-bookworm \
|
||
sh -lc 'rustc scripts/ops/search-worker-logs.rs -O -o dist/jh-logq-linux-amd64'
|
||
```
|
||
|
||
## 目录选择
|
||
|
||
```bash
|
||
# 推荐：直接打开交互向导，自动发现日志目录并按编号选择
|
||
/tmp/jh-logq
|
||
|
||
# 自动发现候选日志目录
|
||
/tmp/jh-logq --list-roots
|
||
|
||
# 已经知道 ICCID 时，也会先自动发现目录并让你按编号选择
|
||
/tmp/jh-logq --choose --iccid 8986000000000000000 --date 2026-05-24 --interface realname
|
||
```
|
||
|
||
目录选择支持：
|
||
|
||
- 回车或 `all`：扫描全部候选目录
|
||
- `1,3-4`：只扫描第 1、3、4 个目录
|
||
- `all,!2,!5-7`：扫描全部，但排除第 2、5、6、7 个目录
|
||
|
||
显式传目录仍然保留给自动化脚本使用：
|
||
|
||
```bash
|
||
/tmp/jh-logq \
|
||
--roots "/data/worker-1/logs:/data/worker-2/logs:/data/worker-3/logs:/data/worker-4/logs" \
|
||
--iccid 8986000000000000000 \
|
||
--date 2026-05-24 \
|
||
--interface realname
|
||
```
|
||
|
||
默认只输出汇总、命中文件和少量样例，不会把窗口刷满。需要原始行时再加：
|
||
|
||
```bash
|
||
/tmp/jh-logq ... --lines --limit 100
|
||
```
