tomcat

# yum install apr apr-devel apr-utils openssl-devel
# tar xf tomcat-native-1.2.23-src.tar.gz 
# cd tomcat-native-1.2.23-src/native/
# ./configure --with-apr=/usr/bin/apr-1-config --with-java-home=/usr/local/jdk --prefix=/usr/local/tomcat
# make && make install

将jdk和tomcat写入环境变量

# vim /etc/profile
export JAVA_HOME=/usr/local/jdk
export JRE_HOME=/usr/local/jdk/jre
export TOMCAT_HOME=/usr/local/tomcat
export PATH=${JAVA_HOME}/bin:${JRE_HOME}/bin:$PATH

可以自己写一个小脚本

<!--这里要吐槽一下java的程序运行的是真的慢，服务刚启动的话8005的套接字端口不会那么快就启用，而关闭服务的时候是要使用到8005端口shutdown的，所以应该把restart服务加上一段时间-->

# chmod +x /etc/init.d/tomcat
# vim /usr/local/tomcat/bin/catalina.sh	# 把环境变量写入相应需要的文件中(tomcat的变量这里没有引用系统环境变量,所以要自己再写上)
