Linux下Tomcat执行shutdown.sh无法结束进程解决方案
Linux下Tomcat执行shutdown.sh的时候，tomcat进程依然还在无法关闭，再次启动tomcat会有两个一样的进程启动，找了好多资料终于解决了这个问题，在此总结一下处理办法，以供参考具体步骤如下：
- 首先通过 ps -ef | grep tomcat 命令找到正在运行的tomcat引用的进程ID
- 通过 kill -9 进程ID 杀掉正在运行的tomcat进程
- 进入到tomcat的 bin 目录 修改 catalina.sh 文件
vi catalina.sh在catalina.sh脚本下面加上如下脚本
if [ -z "$CATALINA_PID" ]; then CATALINA_PID=$PRGDIR/CATALINA_PID cat $CATALINA_PID fi
进入到tomcat的 bin 目录 修改 shutdown.sh 文件
vi shutdown.sh在shutdown.sh脚本最下面的
exec "$PRGDIR"/"$EXECUTABLE" stop "$@"
替换为 exec "$PRGDIR"/"$EXECUTABLE" stop -force "$@"# 原来的脚本：exec "$PRGDIR"/"$EXECUTABLE" stop "$@" 修改成下面的脚本 exec "$PRGDIR"/"$EXECUTABLE" stop -force "$@"
启动tomcat 通过ps -ef | grep tomcat 看是否启动成功，然后执行 shutdown.sh 再通过ps -ef | grep tomcat 看是否结束进程成功
Linux中结束进程<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />
一.试验目的：当我们的进程出现无法操作的时候，我们要采取结束此项任务二.试验步骤：1.开启一个vi，目的是为了下面使用方法来结束VI2.使用Alt+F2切换用户 然后root登陆3.登陆后使用命令：ps –aux 打开进程。4.使用命令：kill -9 16866来结束进程，在使用ps –aux查看是否还有此进程5.对比一下没有此进程了，结束进程成功。

lsof -i:端口号
kill -9 PID
原文：Linux 查看端口占用情况 并 结束进程
有时候使用 ps 命令无法检查出特定的进程，可考虑通过观察端口占用情况结束相关服务
Linux 查看端口占用情况可以使用 lsof 和 netstat 命令，结束进程用 kill 命令
lsof
lsof(list open files)列出当前系统打开的文件
lsof -i:端口号
netstat
netstat -tunlp 用于显示 tcp，udp 的端口和进程等相关情况。
netstat -tunlp | grep 端口号
在查到端口占用的进程后，如果你要杀掉对应的进程可以使用 kill 命令：
kill -9 PID

1 所谓的初始化数据库脚本运行错误
/usr/local/mysql/scripts/mysql_install_db --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data --user=mysql
ps1：mysql安装在/usr/local/mysql/
ps2：没有打印任何日志
2 /usr/local/mysql/目录权限已经全部设定ok，全部为mysql:mysql(mysql用户和mysql群组)
3 另外有个很奇怪的现象是很多人都不提需要把my.cnf拷贝到/etc/目录下，自己拷贝了一下，否则日志也没法生成的。
顺便加了配置项，与上面初始化数据库脚本一致的信息：
[mysqld]
basedir = /usr/local/mysql
datadir = /usr/local/mysql/data
log-error = /usr/local/mysql/mysql_error.log
pid-file = /usr/local/mysql/mysql.pid
user = mysql
tmpdir = /tmp
3 无视最上面脚本运行错误，直接运行mysqld_safe --user=mysql &
