本人有乙個自己寫的**用tcp**伺服器,需要隨系統啟動完成到 目標埠的**操作
命令為 tcp_proxy -l 20011 -r 182.61.145.146 -p 20011
建立服務指令碼檔案
vi /usr/lib/systemd/system/wonrowl_proxy.service
寫入以下內容
[unit]
description=wonrowl proxy install as service test
after=network.target
[service]
type=forking
user=root
execstart=/root/wonrowl_proxy/start.sh
execstop=/root/wonrowl_proxy/stop.sh
[install]
wantedby=default.target
服務檔案中用到的兩個sh指令碼內容分別是
#!/bin/bash
/root/wonrowl_proxy/tcp_proxy -l 20011 -r 182.61.145.146 -p 20011 >> /dev/null &
和#!/bin/bash
killall tcp_proxy
檔案許可權我為了省事,全部777
-rwxrwxrwx 1 root root 9038 oct 7 22:47 main.c
-rwxrwxrwx 1 root root 95 oct 8 14:56 start.sh
-rwxrwxrwx 1 root root 31 oct 8 14:55 stop.sh
-rwxrwxrwx 1 root root 14336 oct 7 22:47 tcp_proxy
萬事具備後
執行 systemctl start wonrowl_proxy
即可啟動服務
通過 systemctl status wonrowl_proxy
檢視結果

執行 systemctl stop wonrowl_proxy
即可關閉服務
通過 systemctl status wonrowl_proxy

此時雖然建立服務成功,但是並沒有具備開機自動的功能,通過 systemctl enable wonrowl_proxy 新增開機自啟動
[root@hecs-x-medium-2-linux-20201005162808 wonrowl_proxy]# systemctl enable wonrowl_proxy
created symlink from /etc/systemd/system/default.target.wants/wonrowl_proxy.service to /usr/lib/systemd/system/wonrowl_proxy.service.
直接reboot
重啟後 systemctl status wonrowl_proxy
[root@hecs-x-medium-2-linux-20201005162808 wonrowl_proxy]# systemctl status wonrowl_proxy
● wonrowl_proxy.service - wonrowl proxy install as service test

可以看到已經自己執行,新增開機啟動成功

1.自己新建乙個指令碼,如centnet service.sh mkdir centnet 建立檔案 centnet service.sh 經過後面的幾個步驟後,這個指令碼在開機的時候會執行,在這個指令碼裡面可以寫你開機的時候想執行的命令,如啟動tomcat,oracle等服務 2.在指令碼中輸入啟...
