tomcat 版本的选择
ApacheTomcat 是 JakartaEE (正式的 JavaEE)技术的一个子集的开放源码软件实现。ApacheTomcat 的不同版本可用于规范的不同版本。规范和相应的 Apache Tomcat 版本之间的映射如下:
| Servlet Spec | JSP Spec | EL Spec | WebSocket Spec | Authentication (JASPIC) Spec | Apache Tomcat Version | Latest Released Version | Supported Java Versions |
|---|---|---|---|---|---|---|---|
| 6.0 | 3.1 | 5.0 | 2.1 | 3.0 | 10.1.x | 10.1.0-M16 (beta) | 11 and later |
| 5.0 | 3.0 | 4.0 | 2.0 | 2.0 | 10.0.x | 10.0.22 | 8 and later |
| 4.0 | 2.3 | 3.0 | 1.1 | 1.1 | 9.0.x | 9.0.64 | 8 and later |
| 3.1 | 2.3 | 3.0 | 1.1 | 1.1 | 8.5.x | 8.5.81 | 7 and later |
| 3.1 | 2.3 | 3.0 | 1.1 | N/A | 8.0.x (superseded) | 8.0.53 (superseded) | 7 and later |
| 3.0 | 2.2 | 2.2 | 1.1 | N/A | 7.0.x (archived) | 7.0.109 (archived) | 6 and later (7 and later for WebSocket) |
| 2.5 | 2.1 | 2.1 | N/A | N/A | 6.0.x (archived) | 6.0.53 (archived) | 5 and later |
| 2.4 | 2.0 | N/A | N/A | N/A | 5.5.x (archived) | 5.5.36 (archived) | 1.4 and later |
| 2.3 | 1.2 | N/A | N/A | N/A | 4.1.x (archived) | 4.1.40 (archived) | 1.3 and later |
| 2.2 | 1.1 | N/A | N/A | N/A | 3.3.x (archived) | 3.3.2 (archived) | 1.1 and later |
mac / linux 下 tomcat 安装
需要预先配置 Java 环境, 并选择对应的版本, 我选择的是 Tomcat 8.5
Tomcat 主页 (https://tomcat.apache.org/index.html)
下载 Tomcat 压缩包。
wget https://mirrors.tuna.tsinghua.edu.cn/apache/tomcat/tomcat-8/v8.5.71/bin/apache-tomcat-8.5.71.tar.gz
解压刚刚下载 Tomcat 包。
tar -zxvf apache-tomcat-8.5.71.tar.gz
修改Tomcat名字。
mv apache-tomcat-8.5.71 /usr/local/Tomcat8.5
为Tomcat授权。
chmod +x /usr/local/Tomcat8.5/bin/*.sh
执行以下命令，修改Tomcat默认端口号为80。
sed -i 's/Connector port="8080"/Connector port="80"/' /usr/local/Tomcat8.5/conf/server.xml
启动
/usr/local/Tomcat8.5/bin/./startup.sh
下载后启动 bin 下的 startup.sh 即可.
在浏览器地址栏输入: http://localhost:8080 或者 http://127.0.0.1:8080, 验证服务是否可用.
启动时报
[root@10-9-64-159 bin]# ./startup.sh
Neither the JAVA_HOME nor the JRE_HOME environment variable is defined
At least one of these environment variable is needed to run this program解决办法: cent os 下安装 open-jre8 即可
su -c "yum install java-1.8.0-openjdk-devel"
mac下查看自己的IP
终端输入ifconfig | grep "inet " | grep -v 127.0.0.1代码 显示ip地址
或者ifconfig en0
常用操作
关闭 Tomcat
./shutdown.sh
查看 Tomcat 版本信息
sh catalina.sh version
解决乱码问题
config/logging.properties
win 控制台乱码的问题, 查看默认编码, 是否没有设置 UTF-8 替换为 gb2312 编码
修改端口号
服务器的默认端口是 8080,也可以将其改成自定义的端口,conf 目录下的 server.xml 文件,将以下语句的 port 值 8080 改为自定义的端口号:(例如8081)
<Connector port="8081" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="8443" />
创建多个 tomcat 容器
需要分别修改 apache-tomcat-8.5.39-solr 中 shutdowm.bat、startup.bat、catalina.bat。
