### 加入
|
||||
使用`crontab -e`，然後加入這一行：
|
||||
`*/1 * * * * /home/awin/script/ddns.sh`
|
||||
|
||||
### 說明
|
||||
![[Pasted image 20240111231507.png]]
|
||||
依序是 **分鐘, 小時, 日期, 月份, 星期, command**
|
||||
參數為 0-59, 0-23, 1-31, 1-21, 0-6, 需要執行的command
|
||||
**※ 星期參數為 0 代表星期日**
|
||||
|
||||
- 【*】：星號，代表任何時刻都接受的意思
|
||||
- 【,】：逗號，代表分隔時段。例如：30 9,17 * * * command，代表早上 9 點半和下午五點半都執行 command。
|
||||
- 【-】：減號，代表一段時間範圍。例如：15 9-12 * * * command，代表從 9 點到 12 點的每個 15 分都執行 command。
|
||||
- 【/n】：斜線，n 代表數字，表示每個 n 單位間隔。例如：*/5 * * * * command，代表每隔 5 分鐘執行一次 command。
|
||||
|
||||
還有一些人性化的參數，一次取代全部五個數字參數
|
||||
- 【@reboot】 ：僅在開機的時候執行一次。
|
||||
- 【@yearly】 ：一年執行一次，和0 0 1 1 * command效果一樣。
|
||||
- 【@annually】：（和@yearly一樣）
|
||||
- 【@monthly】：一個月執行一次，和0 0 1 * * command效果一樣。
|
||||
- 【@weekly】：一個星期執行一次，和0 0 * * 0 command效果一樣。
|
||||
- 【@daily】：每天執行，和0 0 * * * command效果一樣。
|
||||
- 【@midnight】：（和@daily一樣）
|
||||
- 【@hourly】 ：每小時執行，和0 * * * * command效果一樣。
|
||||
|
||||
### 範例
|
||||
- 每 5 分鐘執行一次：
|
||||
- `*/5 * * * * root /usr/libexec/atrun`
|
||||
- 每 5 小時執行一次
|
||||
- `* */5 * * * root /usr/libexec/atrun`
|
||||
- 每天 AM 5:00 執行指令(星號與星號之間要有空隔)
|
||||
- `00 05 * * * username /bin/bash /路徑/command`
|
||||
- 1 至 20 號每天執行一次
|
||||
- `0 1 1-20 * * root /usr/libexec/atrun`
|
||||
- 當分針移到第 5 分時，執行此 cron
|
||||
- `5 * * * * root /usr/libexec/atrun`
|
||||
- 當時針移到 1 點 1 分時，執行此 cron
|
||||
- `1 1 * * * root /usr/libexec/atrun`
|
||||
- 每週一的 1 點 1 分，執行
|
||||
- `1 1 * * 1 root /usr/libexec/atrun`
|
||||
- 2 月 29 日時針到 1 點 1 分，執行
|
||||
- `1 1 29 2 * root /usr/libexec/atrun`
|
||||
- 8 點到 16 點每 5 分鐘執行一次 cron
|
||||
- `/5 8-16 * * * root /usr/libexec/atrun`
|
||||
|
||||

## 看log
|
||||
Raspberry Pi 4沒有`/var/log/syslog`，要使用`journalctl`。
|
||||
```bash
|
||||
journalctl
|
||||
```
|
||||
Or
|
||||
```bash
|
||||
journalctl | grep SOMETHING
|
||||
```
|
||||
|
||||
### 看系統訊息
|
||||
```bash
|
||||
journalctl -p 0
|
||||
```
|
||||
|
||||
#### Error code意思
|
||||
```
|
||||
0: 紧急情况
|
||||
1: 警报
|
||||
2: 危急
|
||||
3: 错误
|
||||
4: 警告
|
||||
5: 通知
|
||||
6: 信息
|
||||
7：调试
|
||||
```
|
||||
|
||||
### 看開機log
|
||||
```bash
|
||||
journalctl --list-boots
|
||||
```
|
||||
|
||||
- 第一個數字顯示的是journald 的唯一的啟動追蹤號碼，你可以在下一個命令中使用它來分析該特定的啟動。
|
||||
- 第二個數字是啟動ID，你也可以在指令中指定。
|
||||
- 接下來的兩個日期、時間組合是儲存在對應文件中的日誌的時間。如果你想找出某個特定日期、時間的日誌或錯誤，這就非常方便了。
|
||||
|
||||
例如：
|
||||
```bash
|
||||
journalctl -b -45
|
||||
```
|
||||
Or
|
||||
```bash
|
||||
journalctl -b 8bab42c7e82440f886a3f041a7c95b98
|
||||
```
|
||||
|
||||
也可以使用 `-x` 選項，在顯示器上加入systemd 錯誤訊息的解釋。在某些情況下，這是個救命稻草。例：
|
||||
```bash
|
||||
journalctl -xb -p 3
|
||||
```
|
||||
|
||||
### 看某一特定時間、日期的日誌記錄
|
||||
使用 `--since` 選項與 `yesterday`、`today`、`tomorrow` 或 `now` 組合。
|
||||
|
||||
以下是一些不同指令的範例。你可以根據你的需求修改它們。它們是不言自明的。以下命令中的日期、時間格式為 `"YYYY-MM-DD HH:MM:SS"`
|
||||
```bash
|
||||
journalctl --since "2020-12-04 06:00:00"
|
||||
journalctl --since "2020-12-03" --until "2020-12-05 03:00:00"
|
||||
journalctl --since yesterday
|
||||
journalctl --since 09:00 --until "1 hour ago"
|
||||
```
|
||||
|
||||
### 看內核特定的記錄
|
||||
```bash
|
||||
journalctl -k
|
||||
```
|
||||
|
||||
### 過濾出某個systemd 服務單元的特定日誌
|
||||
例如，如果要查看 NetworkManager 服務的日誌
|
||||
```bash
|
||||
journalctl -u NetworkManager.service
|
||||
```
|
||||
|
||||
如果不知道service name，看[[systemd#列出系統中的 systemd service]]
|
||||
|
||||
### 查看使用者、群組的日誌
|
||||
```bash
|
||||
id -u debugpoint # 先找出使用者的uid
|
||||
journalctl _UID=1000 --since today
|
||||
```
|
||||
|
||||
### 查看可執行檔的日誌
|
||||
```bash
|
||||
journalctl /usr/bin/gnome-shell --since today
|
||||
```
|
||||
|
||||
### 看log佔用的磁碟空間
|
||||
```bash
|
||||
journalctl --disk-usage
|
||||
```
|
||||
|
||||
### 清除日誌
|
||||
#### 手動清除
|
||||
```bash
|
||||
sudo journalctl --flush --rotate # 將所有日誌歸檔
|
||||
sudo journalctl --vacuum-time=7d # 只保留最近7天的日誌
|
||||
sudo journalctl --vacuum-time=1s # 只保留最近1秒的日誌
|
||||
```
|
||||
或者設定日誌的大小
|
||||
```bash
|
||||
sudo journalctl --vacuum-size=400M # 保留最後400M
|
||||
```
|
||||
|
||||
#### 自動清除
|
||||
修改`/etc/systemd/journald.conf`，裡面有下面幾個設定項：
|
||||
- `SystemMaxUse`: 指定日志在持久性存储中可使用的最大磁盘空间。例：`SystemMaxUse=500M`
|
||||
- `SystemKeepFree`: 指定在将日志条目添加到持久性存储时，日志应留出的空间量。例：`SystemKeepFree=100M`
|
||||
- `SystemMaxFileSize`: 控制单个日志文件在被轮换之前在持久性存储中可以增长到多大。例：`SystemMaxFileSize=100M`
|
||||
- `RuntimeMaxUse`: 指定在易失性存储中可以使用的最大磁盘空间（在 /run 文件系统内）。例：`RuntimeMaxUse=100M`
|
||||
- `RuntimeKeepFree`: 指定将数据写入易失性存储（在 /run 文件系统内）时为其他用途预留的空间数量。例：`RuntimeMaxUse=100M`
|
||||
- `RuntimeMaxFileSize`: 指定单个日志文件在被轮换之前在易失性存储（在 /run 文件系统内）所能占用的空间量。例：`RuntimeMaxFileSize=200M`
|
||||
|
||||
修改後記得重啟`journalctl`：
|
||||
```bash
|
||||
sudo systemctl restart systemd-journald
|
||||
```
|
||||
|
||||
也請記得[[確認日誌的完整性]]
|
||||
|
||||
### 確認日誌的完整性
|
||||
```bash
|
||||
journalctl --verify
|
||||
```
|
||||
|
||||

{"id":"84c3e0d9a25b9cfd","type":"text","text":"## 看log\nRaspberry Pi 4沒有`/var/log/syslog`，要使用`journalctl`。\n```bash\njournalctl\n```\nOr \n```bash\njournalctl | grep SOMETHING\n```\n\n### 看系統訊息\n```bash\njournalctl -p 0\n```\n\n#### Error code意思\n```\n0: 紧急情况\n1: 警报\n2: 危急\n3: 错误\n4: 警告\n5: 通知\n6: 信息\n7：调试\n```\n\n### 看開機log\n```bash\njournalctl --list-boots\n```\n\n- 第一個數字顯示的是journald 的唯一的啟動追蹤號碼，你可以在下一個命令中使用它來分析該特定的啟動。\n- 第二個數字是啟動ID，你也可以在指令中指定。\n- 接下來的兩個日期、時間組合是儲存在對應文件中的日誌的時間。如果你想找出某個特定日期、時間的日誌或錯誤，這就非常方便了。\n\n例如：\n```bash\njournalctl -b -45\n```\nOr\n```bash\njournalctl -b 8bab42c7e82440f886a3f041a7c95b98\n```\n\n也可以使用 `-x` 選項，在顯示器上加入systemd 錯誤訊息的解釋。在某些情況下，這是個救命稻草。例：\n```bash\njournalctl -xb -p 3\n```\n\n### 看某一特定時間、日期的日誌記錄\n使用 `--since` 選項與 `yesterday`、`today`、`tomorrow` 或 `now` 組合。\n\n以下是一些不同指令的範例。你可以根據你的需求修改它們。它們是不言自明的。以下命令中的日期、時間格式為 `\"YYYY-MM-DD HH:MM:SS\"`\n```bash\njournalctl --since \"2020-12-04 06:00:00\"\njournalctl --since \"2020-12-03\" --until \"2020-12-05 03:00:00\"\njournalctl --since yesterday\njournalctl --since 09:00 --until \"1 hour ago\"\n```\n\n### 看內核特定的記錄\n```bash\njournalctl -k\n```\n\n### 過濾出某個systemd 服務單元的特定日誌\n例如，如果要查看 NetworkManager 服務的日誌\n```bash\njournalctl -u NetworkManager.service\n```\n\n如果不知道service name，看[[systemd#列出系統中的 systemd service]]\n\n### 查看使用者、群組的日誌\n```bash\nid -u debugpoint # 先找出使用者的uid\njournalctl _UID=1000 --since today\n```\n\n### 查看可執行檔的日誌\n```bash\njournalctl /usr/bin/gnome-shell --since today\n```\n\n### 看log佔用的磁碟空間\n```bash\njournalctl --disk-usage\n```\n\n### 清除日誌\n#### 手動清除\n```bash\nsudo journalctl --flush --rotate # 將所有日誌歸檔\nsudo journalctl --vacuum-time=7d # 只保留最近7天的日誌\nsudo journalctl --vacuum-time=1s # 只保留最近1秒的日誌\n```\n或者設定日誌的大小\n```bash\nsudo journalctl --vacuum-size=400M # 保留最後400M\n```\n\n#### 自動清除\n修改`/etc/systemd/journald.conf`，裡面有下面幾個設定項：\n- `SystemMaxUse`: 指定日志在持久性存储中可使用的最大磁盘空间。例：`SystemMaxUse=500M`\n- `SystemKeepFree`: 指定在将日志条目添加到持久性存储时，日志应留出的空间量。例：`SystemKeepFree=100M`\n- `SystemMaxFileSize`: 控制单个日志文件在被轮换之前在持久性存储中可以增长到多大。例：`SystemMaxFileSize=100M`\n- `RuntimeMaxUse`: 指定在易失性存储中可以使用的最大磁盘空间（在 /run 文件系统内）。例：`RuntimeMaxUse=100M`\n- `RuntimeKeepFree`: 指定将数据写入易失性存储（在 /run 文件系统内）时为其他用途预留的空间数量。例：`RuntimeMaxUse=100M`\n- `RuntimeMaxFileSize`: 指定单个日志文件在被轮换之前在易失性存储（在 /run 文件系统内）所能占用的空间量。例：`RuntimeMaxFileSize=200M`\n\n修改後記得重啟`journalctl`：\n```bash\nsudo systemctl restart systemd-journald\n```\n\n也請記得[[確認日誌的完整性]]\n\n### 確認日誌的完整性\n```bash\njournalctl --verify\n```\n\n### 參考\n- [系統運作|如何使用journalctl 檢視和分析systemd 日誌（附實例）](https://linux.cn/article-15544-1.html)","x":-1659,"y":1180,"width":928,"height":640}
