IT｜作業系統｜Linux｜Ubuntu rc.local systemd 開機自動執行應用程式

作業系統版本 Ubuntu 18.04 

使用 systemd 設置開機啓動：

systemd 默認讀取 /etc/systemd/system 下的配置文件該目錄下的文件會鏈接 /lib/systemd/system/ 下的文件。

一般系統安裝完 /lib/systemd/system/ 下會有 rc-local.service文件，即需要的配置文件。

ln -fs /lib/systemd/system/rc-local.service /etc/systemd/system/rc-local.service

cd /etc/systemd/system/

cat rc-local.service

rc-local.service内容

1) [Unit] 區塊：啓動順序與依賴關係。

2) [Service] 區塊：啓動行為,如何啓動，啓動類型。

3) [Install] 區塊，定義如何安裝這個配置文件，即怎樣做到開機啓動。

建立 /etc/rc.local 

sudo touch /etc/rc.local

chmod 755 /etc/rc.local

編輯 /etc/rc.local

sudo nano /etc/rc.local

內容如下：

========

#!/bin/bash

#

# rc.local

#

# This script is executed at the end of each multiuser runlevel.

# Make sure that the script will "exit 0" on success or any other

# value on error.

#

# In order to enable or disable this script just change the execution

# bits.

#

# By default this script does nothing.:

echo "test rc " >> /home/lilee/Signal/project/logs/mylog

/bin/bash /home/lilee/Signal/project/redis-service.sh 1>>   /home/lilee/Signal/project/logs/mylog   # send stderr from rc.local to a log file

2>&1   # send stdout to the same log file

sleep 10

/bin/bash /home/lilee/Signal/project/signal-priority.sh 1>> /home/lilee/Signal/project/logs/mylog   # send stderr from rc.local to a log file

2>&1   # send stdout to the same log file

exit 0

編輯  /home/lilee/Signal/project/redis-service.sh

#!/bin/bash

redis-server /home/lilee/Signal/redis-4.0.1/redis.conf &

exit 0

賦予檔案執行權限
