chmod -R 755 /opt/apr/
方法1：
参考：
https://www.cnblogs.com/hyzhou/p/7077012.html
更改配置文件
vim /etc/profile
末尾添加：
#apr
export LD_LIBRARY_PATH=/opt/apr/apr/lib
保存，生效：
source /etc/profile
修改server.xml
cd /usr/local/apache-tomcat-7.0.53/conf
vim server.xml
<Connector port="8090" protocol="HTTP/1.1”中的protocol修改成org.apache.coyote.http11.Http11AprProtocol
重启Tomcat
查看tomcat启动情况
cd /usr/local/apache-tomcat-7.0.53/logs
tail -100f catalina.out
INFO: Deploying web application directory /usr/local/apache-tomcat-7.0.53/webapps/manager

Aug 20, 2019 4:53:41 PM org.apache.catalina.startup.Catalina start

与参考博主的结果不一样
于是，我把所有的配置都还原，结果

Aug 20, 2019 5:16:18 PM org.apache.coyote.AbstractProtocol start

Aug 20, 2019 5:16:18 PM org.apache.catalina.startup.Catalina start

居然和参考博主的结果一样
这TM是在逗我么

方法2：
参考：

cd /usr/local/apache-tomcat-7.0.53/bin

但8080端口网页是打不开的
于是，我将server.xml中，Connector executor 8080端口改为8090
<!-- 添加配置 -->
<Connector executor="tomcatThreadPool"
maxThreads="1000"
URIEncoding="UTF-8"
port="8090"
protocol="org.apache.coyote.http11.Http11AprProtocol"
connectionTimeout="20000"
enableLookups="false"
redirectPort="8443" />
结果
INFO: Deploying web application directory /usr/local/apache-tomcat-7.0.53/webapps/manager
Aug 20, 2019 5:43:59 PM org.apache.coyote.AbstractProtocol start
INFO: Starting ProtocolHandler ["http-apr-8090"]

Aug 20, 2019 5:43:59 PM org.apache.catalina.startup.Catalina start

算是成功吧
但我不明白我不进行配置为啥也是apr模式。。。。留着，等以后有机缘懂了再记录。
