安裝jdk
1、CentOS 6.X 和 7.X 自帶有OpenJDK runtime environment (openjdk)。它是一個在linux上實現開源的Java 平臺。yum search java | grep -i --color JDK2、在CentOS linux安裝 JAVA SDK 在命令列終端以root使用者 輸入以下命令yum安裝 OpenSDK :
yum install java-1.8.0-openjdk java-1.8.0-openjdk-devel #安裝openjdk3、配置環境變數 編輯
vi /etc/profile
export JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.191.b12-0.el7_5.x86_64 export CLASSPATH=$JAVA_HOME/lib/*.* export PATH=$PATH:$JAVA_HOME/bin生效:
source /etc/profile #讓設定立即生效。確認是否成功:
echo $JAVA_HOME echo $CLASSPATH echo $PATH4、檢視是否安裝成功
java -version
安裝tomcat
1、安裝wgetyum install wget2、下載、解壓安裝tomcat
wget https://mirrors.tuna.tsinghua.edu.cn/apache/tomcat/tomcat-9/v9.0.13/bin/apache-tomcat-9.0.13.tar.gz3、 把startup.sh和shutdown.sh這兩個腳本里的最前面加上下面一段:tar xvf apache-tomcat-9.0.13.tar.gz -C /usr/local/ ## 解壓 mv /usr/local/apache-tomcat-9.0.13/ /usr/local/tomcat/ ##剪下到tomcat目錄下
export JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.191.b12-0.el7_5.x86_64 export TOMCAT_HOME=/usr/local/tomcat export CATALINA_HOME=/usr/local/tomcat export CLASS_PATH=$JAVA_HOME/bin/lib:$JAVA_HOME/jre/lib:$JAVA_HOME/lib/tool.jar export PATH=$PATH:/usr/local/java/bin:/usr/local/tomcat/bin4、啟動tomcat
/usr/local/tomcat/bin/startup.sh
5、開放預設埠8080
firewall-cmd --zone=public --add-port=8080/tcp --permanent #重啟 systemctl restart firewalld.service #重新載入載 firewall-cmd --reload
6、瀏覽器中訪問http://192.168/226/129:8080,出現下面頁面,證明安裝成功
7、設定開機自啟
vi /etc/rc.d/init.d/tomcat
寫入以下內容:
#!/bin/bash # # kenny [email protected] # /etc/rc.d/init.d/tomcat # init script for tomcat precesses # # processname: tomcat # description: tomcat is a j2se server # chkconfig: 2345 86 16 # description: Start up the Tomcat servlet engine. if [ -f /etc/init.d/functions ]; then . /etc/init.d/functions elif [ -f /etc/rc.d/init.d/functions ]; then . /etc/rc.d/init.d/functions else echo -e "/atomcat: unable to locate functions lib. Cannot continue." exit -1 fi RETVAL=$? CATALINA_HOME="/usr/local/tomcat" case "$1" in start) if [ -f $CATALINA_HOME/bin/startup.sh ]; then echo $"Starting Tomcat" $CATALINA_HOME/bin/startup.sh fi ;; stop) if [ -f $CATALINA_HOME/bin/shutdown.sh ]; then echo $"Stopping Tomcat" $CATALINA_HOME/bin/shutdown.sh fi ;; *) echo $"Usage: $0 {start|stop}" exit 1 ;; esac exit $RETVAL
8、新增許可權,使得指令碼檔案可執行
chmod 755 /etc/rc.d/init.d/tomcat
9、新增到服務中
chkconfig --add /etc/rc.d/init.d/tomcat
10、在catalina.sh中新增如下內容
#auto startup tomcat config export JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.191.b12-0.el7_5.x86_64 export TOMCAT_HOME=/usr/local/tomcat export CATALINA_HOME=/usr/local/tomcat export CLASS_PATH=$JAVA_HOME/bin/lib:$JAVA_HOME/jre/lib:$JAVA_HOME/lib/tool.jar export PATH=$PATH:/usr/local/java/bin:/usr/local/tomcat/bin
重啟tomcat
結語
注意環境變數的配置,jdk的路徑問題。
