用tomcat用户开机启动

创建用户

groupadd tomcat
useradd -g tomcat   tomcat   -s /sbin/nologin
chown tomcat.tomcat -R /usr/local/tomcat/*

编译 jsvc

cd /usr/local/tomcat/bin/
tar xf commons-daemon-native.tar.gz
cd commons-daemon-1.1.0-native-src/unix/
./configure --with-java=$JAVA_HOME
make

cp jsvc /usr/local/tomcat/bin/
cp /usr/local/tomcat/bin/daemon.sh    /etc/init.d/tomcat

修改启动文件，内存优化

vim   /etc/init.d/tomcat
#!/bin/sh
# chkconfig: 2345 81 91
