cd /etc/init.d/進(jìn)入目錄 - 創(chuàng)建文件canal,把下面內(nèi)容粘貼進(jìn)去，修改java路徑和canal安裝路徑葬馋。

- 給腳本添加權(quán)限
chmod 755 canal - 添加服務(wù)到開機(jī)項
chkconfig --add canal - 設(shè)置為開機(jī)啟動
chkconfig canal on - 測試
service canal start
發(fā)現(xiàn)一個有意思的事情,canal 如果不正常退出服務(wù),比如虛擬機(jī)強(qiáng)制重啟等,canal開機(jī)就無法正常啟動,報錯如下
found canal.pid , Please run stop.sh first ,then startup.sh canal is started;
說的就是找到了canal.pid 請先運(yùn)行stop.sh,實際上canal服務(wù)已經(jīng)停止了.
這個時候就簡單點(diǎn);
