//從官網(wǎng)下載tomcat7[cjh@iZwz9catu2mrq92b07d1d0Z ~]$ wget http://mirrors.tuna.tsinghua.edu.cn/apache/tomcat/tomcat-7/v7.0.82/bin/apache-tomcat-7.0.82.tar.gz//檢查壓縮包文件[cjh@iZwz9catu2mrq92b07d1d0Z ~]$ tar -ztvf apache-tomcat-7.0.82.tar.gz//解壓[cjh@iZwz9catu2mrq92b07d1d0Z ~]$ tar -zxvf apache-tomcat-7.0.82.tar.gz[cjh@iZwz9catu2mrq92b07d1d0Z ~]$ lsapache-tomcat-7.0.82 apache-tomcat-7.0.82.tar.gz |
注：當(dāng)我們嘗試啟動(dòng)tomcat時(shí)可能會(huì)遇到啟動(dòng)非常慢的情況，并且在啟動(dòng)日志中會(huì)看到類似以下的信息
|

2
|
<DATE> org.apache.catalina.util.SessionIdGenerator createSecureRandomINFO: Creation of SecureRandom instance for session ID generation using [SHA1PRNG] took [5172] milliseconds. |
關(guān)于本問題請(qǐng)參考官方文章末尾有說明 官方說明
問題說明：
Tomcat 7+ heavily relies on SecureRandom class to provide random values for its session ids and in other places. Depending on your JRE it can cause delays during startup if entropy source that is used to initialize SecureRandom is short of entropy
譯：tomcat7+嚴(yán)重依賴SecureRandom類為會(huì)話ids和其它地方提供的隨機(jī)值，這會(huì)導(dǎo)致啟動(dòng)過程出現(xiàn)延遲。
解決辦法：
There is a way to configure JRE to use a non-blocking entropy source by setting the following system property: -Djava.security.egd=file:/dev/./urandom
譯：添加jvm參數(shù) -Djava.security.egd=file:/dev/./urandom
