解决tomcat启动慢
1.在Tomcat环境中解决
可以通过配置JRE使用非阻塞的Entropy Source。
在catalina.sh中加入这么一行:-Djava.security.egd=file:/dev/./urandom 即可。
2.在JVM环境中解决(*实测,真实好使)
打开$JAVA_PATH/jre/lib/security/java.security这个文件,找到下面的内容:
securerandom.source=file:/dev/urandom
替换成
securerandom.source=file:/dev/./urandom
实例配置:
[root@df-search bin]# cat catalina.sh
# USE_NOHUP (Optional) If set to the string true the start command will # use nohup so that the Tomcat process will ignore any hangup # signals. Default is "false" unless running on HP-UX in which # case the default is "true" # ----------------------------------------------------------------------------- export JAVA_OPTS="-Djava.security.egd=file:/dev/./urandom -Dons.client.logRoot=/root/logs -Dons.client.logLevel=WARN -Dons.client.logFileMaxIndex=20" # OS specific support. $var _must_ be set to either true or false. cygwin=false
