环境: centos7.9 tomcat9 jdk1.8

一.阿里云申请 免费SSL

按照官网的方法并未成功启动!

443 80端口加入安全组

阿里云申请免费ssl 下载后解压将localhost-rsa.pfx上传至tomcat 的 /usr/local/tomcat/apache-tomcat-9/conf/ 下

配置service.xml

修改 redirectPort="443"

            <Connector port="80" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="443"
               maxParameterCount="1000"
               />

新增 Connector 可以将xxx.pfx文件 修改为localhost-rsa.pfx

    <Connector port="443" protocol="org.apache.coyote.http11.Http11NioProtocol"
               maxThreads="150" SSLEnabled="true"
               maxParameterCount="1000"
               >
        <SSLHostConfig>
            <Certificate certificateKeystoreFile="/usr/local/tomcat/apache-tomcat-9/conf/localhost-rsa.pfx"
                         certificateKeystorePassword="密码"
                         type="RSA" />
        </SSLHostConfig>
    </Connector>

二.下载安装JDK,yum安装后面依赖缺少时还要重新配置环境变量

（1）查看是否已安装jdk JDK1.8 验证 mx1f

rpm -qa | grep jdk

（2）查看jdk版本

java -version

（3）删除所有旧版本jdk

1. 删除java的安装目录

#卸载所有openjdk相关文件输入
yum -y remove java-1.8.0-openjdk*

#卸载tzdata-java
yum -y remove tzdata-java.noarch  

2. vi /etc/profile 删除关于java的配置
3. source /etc/profile 立刻生效; java -version 此时查不到
4. 下载后解压 配置jdk 环境 在 /etc/ 下修改profile 将如下粘贴到最后

export JAVA_HOME=/usr/local/java/jdk8
export JRE_HOME=/usr/local/java/jdk8/jre
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
export PATH=$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$PATH:$HOME/bin

一些问题

1.Failed to initialize component [Connector[HTTP/1.1-443]] ;

• 检查上述文件的por是否正确
• 查看catalina.2023-08-03.log 日志信息,例如: 命名写错了FileNotFoundException该正后就行了

2.The Apache Tomcat Native library which allows using OpenSSL was not found on the java.library.path: [/usr/java/packages/lib/am

原因:缺少依赖 需要配置安装依赖 可参考

1、安装 openssl

yum install apr-devel openssl-devel

2、安装 tomcat-native

tomcat-native 下载解压安装。tomcat-native-1.2.23-src.tar.gz

# 解压
tar xzcf tomcat-native-1.2.23-src.tar

# 进入/native下
cd tomcat-native-1.2.23-src/native

# 安装  
./configure 

# 安装
make && make install

3、配置 tomcat 的 setenv.sh 文件

在tomcat安装目录的bin /usr/local/tomcat/apache-tomcat-9/bin/ 下setenv.sh 文件则新建一个

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/apr/lib

4. minio无法使用 Unsupported or unrecognized SSL message

无解决 准备换阿里云存储或者其他 OSS云存储
