CentOS7环境安装tomcat

环境准备

由于是在练习，为了方便，我们可以

1.关闭防火墙

 systemctl  disable firewalld.service

systemctl  stop firewalld.service

2.关闭selinux

在/etc/selinux/config中，设置：

SELINUX=disabled

3.准备jdk---》jdk-8u333-linux-x64.tar.gz这个包

    可以在编程宝库下载：http://www.codebaoku.com/jdk/jdk-oracle-jdk1-8.html#jdk8u333

创建目录：

mkdir -p  /usr/java/

解压：

 tar  xf jdk-8u333-linux-x64.tar.gz -C /usr/java/

配置：

vim   /etc/profile.d/java.sh

JAVA_HOME=/usr/java/jdk1.8.0_333
PATH=$JAVA_HOME/bin:$PATH
CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
export JAVA_HOME CLASSPATH PATH

测试

source /etc/profile.d/java.sh

java -version

 4.准备apache-tomcat-8.5.70.tar.gz这个包

解压到  /usr/local：

[root@localhost ~]# tar xf apache-tomcat-8.5.70.tar.gz -C /usr/local/

创建软链接

[root@localhost ~]# ln -s /usr/local/apache-tomcat-8.5.70 /usr/local/tomcat

编写配置：

 echo 'export TOMCAT_HOME=/usr/local/tomcat'>>/etc/profile.d/tomcat.sh

检查：

[root@localhost ~]# source /etc/profile.d/tomcat.sh

[root@localhost ~]# /usr/local/tomcat/bin/version.sh
Using CATALINA_BASE:   /usr/local/tomcat
Using CATALINA_HOME:   /usr/local/tomcat
Using CATALINA_TMPDIR: /usr/local/tomcat/temp
Using JRE_HOME:        /usr/java/jdk1.8.0_333
Using CLASSPATH:       /usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar
Using CATALINA_OPTS:
Server version: Apache Tomcat/8.5.70
Server built:   Aug 9 2021 16:17:14 UTC

Architecture:   amd64
JVM Version:    1.8.0_333-b02
JVM Vendor:     Oracle Corporation

 运行：

在/usr/local/apache-tomcat-8.5.70/bin   目录下

[root@localhost bin]# ./startup.sh
Using CATALINA_BASE:   /usr/local/apache-tomcat-8.5.70
Using CATALINA_HOME:   /usr/local/apache-tomcat-8.5.70
Using CATALINA_TMPDIR: /usr/local/apache-tomcat-8.5.70/temp
Using JRE_HOME:        /usr/java/jdk1.8.0_333
Using CLASSPATH:       /usr/local/apache-tomcat-8.5.70/bin/bootstrap.jar:/usr/local/apache-tomcat-8.5.70/bin/tomcat-juli.jar
Using CATALINA_OPTS:
Tomcat started.

 web站点jpress部署

1.启动mariadb数据库

 下载：yum install -y mariadb-server
 启动：systemctl start mariadb.service
 开机自启：systemctl enable mariadb.service

 2.创建数据库并授权

 mysql -e "create database jpress DEFAULT CHARACTER SET utf8;"
 mysql -e "grant all on jpress.* to jpress@'localhost' identified by '123456';"

 3.将jpress安装包放到/usr/local/tomcat/webapps/

 cp jpress-web-newest.war  /usr/local/tomcat/webapps/

ls /usr/local/tomcat/webapps/

 4.访问

http://IP:8080/jpress-web-newest/install

如：

http://192.168.197.148:8080/jpress-web-newest/install

 

5. 安装jpress
