cenos7安裝配置tomcat8，新增到系統服務，使用systemctl直接啟動

建立目錄

mkdir -p /usr/local/tomcat

下載tomcat壓縮檔案

解壓到指定目錄

tar -zxvf apache-tomcat-8.5.31.tar.gz -C /usr/local/tomcat/

執行

cd /usr/local/tomcat/apache-tomcat-8.5.31/ ./startup.sh ./shutdown.sh

將tomcat作為系統服務，使用systemctl直接啟動方法。

修改tomcat的catalina.sh檔案，vim開啟 ：set number 應該是142行下面新增 CATALINA_PID="$CATALINA_BASE/tomcat.pid"

138 # Only set CATALINA_HOME if not already set
139 [ -z "$CATALINA_HOME" ] && CATALINA_HOME=`cd "$PRGDIR/.." >/dev/null; pwd`
140 
141 # Copy CATALINA_BASE from CATALINA_HOME if not already set
142 [ -z "$CATALINA_BASE" ] && CATALINA_BASE="$CATALINA_HOME"
143 CATALINA_PID="$CATALINA_BASE/tomcat.pid"
 

144 # Ensure that any user defined CLASSPATH variables are not used on startup,
145 # but allow them to be specified in setenv.sh, in rare case when it is needed.

然後在/usr/lib/systemd/system下面建立tomcat.service檔案

vim /usr/lib/systemd/system/tomcat.service

systemctl管理tomcat

• systemctl enable tomcat 開機啟動
• systemctl status tomcat 檢視狀態
• systemctl start / stop / restart tomcat 開始/停止/重啟 tomcat

遇到的問題

如果只是配好了tomcat.pid就啟動過tomcat的話，需要在所有配置完成後 在tomcat關閉的情況下 刪除 rm tomcat.pid 檔案，然後使用上面的命令來啟動tomcat
