Linux安裝JDK、Tomcat並將其做成Service服務__Linux

環境 Ubuntu 16.04 LTS jdk1.8.0_161 apache-tomcat-7.0.82 安裝JDK並配置環境變數

安裝JDK：

//解壓縮包tar -zxvf jdk-8u161-linux-x64.tar.gz //將jdk目錄拷貝至/user/local/目錄下sudo cp -r jdk1.8.0_161 /usr/local/

修改環境變數：

//安裝vim命令sudo apt install vim//編輯系統配置sudo vim /etc/profile

在/etc/profile末尾添加如下配置：

JAVA_HOME=/usr/local/jdk1.8.0_161JRE_HOME=/usr/local/jdk1.8.0_161/jreCLASS_PATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:$JRE_HOME/libPATH=$PATH:$JAVA_HOME/bin:$JRE_HOME/binexport JAVA_HOME JRE_HOME CLASS_PATH PATH

使得配置生效：

//查看當前配置hanchao@hanchao-virtual-machine:/etc$ echo $PATH/home/hanchao/bin:/home/hanchao/.local/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin//生效hanchao@hanchao-virtual-machine:/etc$ source /etc/profile//再次查看當前配置hanchao@hanchao-virtual-machine:/etc$ echo $PATH/home/hanchao/bin:/home/hanchao/.local/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin:/snap/bin:/usr/local/jdk1.8.0_161/bin:/usr/local/jdk1.8.0_161/jre/bin

查看JDK版本

hanchao@hanchao-virtual-machine:/etc$ java -versionjava version "1.8.0_161"Java(TM) SE Runtime Environment (build 1.8.0_161-b12)Java HotSpot(TM) 64-Bit Server VM (build 25.161-b12, mixed mode)

安裝啟動Tomcat

安裝：

unzip -q apache-tomcat-7.0.82.zip sudo cp -r apache-tomcat-7.0.82 /usr/local/tomcatsudo mv tomcat apache-tomcat-7.0.82

啟動Tomcat：

root@hanchao-virtual-machine:/usr/local/apache-tomcat-7.0.82/bin# chmod +x *.shroot@hanchao-virtual-machine:/usr/local/apache-tomcat-7.0.82/bin# ./startup.sh Using CATALINA_BASE:   /usr/local/apache-tomcat-7.0.82Using CATALINA_HOME:   /usr/local/apache-tomcat-7.0.82Using CATALINA_TMPDIR: /usr/local/apache-tomcat-7.0.82/tempUsing JRE_HOME:        /usr/local/jdk1.8.0_161/jreUsing CLASSPATH:       /usr/local/apache-tomcat-7.0.82/bin/bootstrap.jar:/usr/local/apache-tomcat-7.0.82/bin/tomcat-juli.jarTomcat started.

測試服務：

在瀏覽器中輸入http://localhost:8080/，成功進入tomcat首頁。

關閉tomcat：

root@hanchao-virtual-machine:/usr/local/apache-tomcat-7.0.82/bin# ./shutdown.sh 

將Tomcat做成Service服務

拷貝啟動指令碼至/etc/init.d/：

cp /usr/java/tomcat/bin/catalina.sh /etc/init.d/tomcat    #將catalina.sh重新命名為tomcat，作為今後的服務名

修改啟動指令碼配置：

sudo vim /etc/init.d/tomcat

在/etc/init.d/tomcat檔案中，在首行之後插入如下配置：

### BEGIN INIT INFO# Provides:          tomcat# Required-Start:    $remote_fs $network# Required-Stop:     $remote_fs $network# Default-Start:     2 3 4 5# Default-Stop:      0 1 6# Short-Description: The tomcat Java Application Server### END INIT INFOCATALINA_HOME=/usr/local/apache-tomcat-7.0.82JAVA_HOME=/usr/local/jdk1.8.0_161

添加指令碼的執行許可權：

chmod 755 /etc/init.d/tomcat

佈建服務：

有的Linux系統中通過chkconfig命令佈建服務。

在Ubuntu 16.04 LTS中是沒有chkconfig命令的，所以用update-rc.d 來代替。

//佈建服務sudo update-rc.d tomcat defaults//使服務生效sudo update-rc.d tomcat enable

用Service啟動服務：

//啟動服務sudo service tomcat start//停止服務sudo service tomcat stop//重啟服務sudo service tomcat restart//查看運行狀態sudo service tomcat status
