在ubuntu服务器上安装tomcat 9

2022-10-25 09:33:22

前提条件：

确保ubuntu服务器上已经安装 java 8 或更高版本，安装java8可以参考我的另一篇博文通过 ppa 在ubuntu server 上安装java 8

java -version

java version "1.8.0_191"
Java(TM) SE Runtime Environment (build 1.8.0_191-b12)
Java HotSpot(TM) 64-Bit Server VM (build 25.191-b12, mixed mode)

第一步：下载安装包，解压缩

cd /usr/local

sudo wget http://www-us.apache.org/dist/tomcat/tomcat-9/v9.0.12/bin/apache-tomcat-9.0.12.tar.gz

sudo tar xzf apache-tomcat-9.0.12.tar.gz

sudo mv apache-tomcat-9.0.12 apache-tomcat9

第二步：配置环境变量

echo "export CATALINA_HOME="/usr/local/apache-tomcat9"" >> ~/.bashrc

echo "export JAVA_HOME="/usr/lib/jvm/java--oracle"" >> ~/.bashrc

echo "export JRE_HOME="/usr/lib/jvm/java--oracle/jre"" >> ~/.bashrc

source ~/.bashrc

第三步：设置用户账号

编辑conf/tomcat-users.xml 在 <tomcat-users> </tomcat-users> 标签之间添加以下管理账号.

<!-- user manager can access only manager section -->

<role rolename="manager-gui" />

<user username="manager" password="_SECRET_PASSWORD_" roles="manager-gui" />

<!-- user admin can access manager and admin section both -->

<role rolename="admin-gui" />

<user username="admin" password="_SECRET_PASSWORD_" roles="manager-gui,admin-gui" />

第四步：允许远程IP访问tomcat 主机已经管理tomcat

tomcat默认自允许localhost 访问&管理tomcat服务器，修改以下两个文件中允许访问主机的IP地址的正则表达式

Manager File: ./webapps/manager/META-INF/context.xml
Host Manager File: ./webapps/host-manager/META-INF/context.xml

第五步：启动tomcat

cd /usr/local/apache-tomcat9

chmod +x ./bin/startup.sh

./bin/startup.sh

Using CATALINA_BASE: /usr/local/apache-tomcat9
Using CATALINA_HOME: /usr/local/apache-tomcat9
Using CATALINA_TMPDIR: /usr/local/apache-tomcat9/temp
Using JRE_HOME: /usr/lib/jvm/java-8-oracle/jre
Using CLASSPATH: /usr/local/apache-tomcat9/bin/bootstrap.jar:/usr/local/apache-tomcat9/bin/tomcat-juli.jar
Tomcat started.

第六步：验证启动成功

打开浏览器，访问网站，如果界面显示正常则启动成功。
