安装jdk

设置JAVA_HOME等环境变量

sed -i 's#securerandom.source=file:/dev/random#securerandom.source=file:/dev/./urandom#g' "$JAVA_HOME/jre/lib/security/java.security"

安装tomcat

复制两份tomcat到/usr/local/目录下

[root@zrd /usr/local]# ls tomcat*
tomcat1:
bin  conf  lib  LICENSE  logs  NOTICE  RELEASE-NOTES  RUNNING.txt  temp  webapps  work

tomcat2:
bin  conf  lib  LICENSE  logs  NOTICE  RELEASE-NOTES  RUNNING.txt  temp  webapps  work

chown -R tomcat /usr/local/tomcat*

配置

• pid

mkdir -p /var/run/tomcat && chown tomcat.tomcat -R /var/run/tomcat && chmod 600 /var/run/tomcat
