程序和进程
程序和进程
- 进程的状态
-
- 如何杀死进程
- 小实验
- 程序是保存在硬盘中，是静态保存的代码
- 进程是在cpu及内存中运行的代码，是动态执行的代码，他有父进程，然后父进程产生子进程
- 每个程序可以创建一个或者多个进程
- 当子进程快要结束时会发送一个信息通知父进程，但是父进程如果未响应的话，子进程就会转变成僵尸进程
- 如果父进程直接被杀死，它下面的子进程就会变成孤儿进程，然后作为pid=1的systemd回去管理这些孤儿进程
进程的状态
- 运行状态
- 可中断睡眠状态
- 不可中断睡眠状态
- 僵死状态
- 停止状态
用ps -elf或者ps aux来查看进程
user：用户
pid：子进程号
ppid：父进程号
%cpu：cup百分占比
%MEM：内存百分占比
VSZ：虚拟内存
RSS：实际占用物理内存
TTY：终端，TTY1代表图形化界面，TTY2-6代表字符界面，PTS代表通过远程连接，？代表没有终端。
STAT：S可中断睡眠，D不可中断睡眠，R运行状态，Z僵死状态，T停止状态，s控制性进程，<高优先级，N低优先级，l多线程，+当前进程运行前台。
COMMAND：命令，带[ ]是内核态，不带[ ]是用户态
top查看实时进程
默认以CPU降序排列，M是内存降序，P是CPU降序，N是pid降序排列，s改变更新时间
字段up是运行时间
load average：平均负载，越大说明等待运行的越多
- top -d 5，设置更新时间
- top -p 8025，只看8025的进程
- ps -o user，pid 指定参数显示
- ps aux |grep vim | grep -v grep 查看vim进程号
- pstree -u tom 针对用户查看进程
- pstree -p 显示进程的pid
- pgrep -l vim 指定进程名看进程号
- pgrep -u tom 指定用户名看用户运行进程号
如何杀死进程
- kill 12987 杀掉pid为12987进程
- kill -9 13140 强行杀掉此进程，1 重启 9强制杀死 15等完成进程在杀死
- kill -l 查看kill参数
- killall vim 跟进程名杀死
- pkill vim 跟进程名杀死
- kill -9 %1 杀死后台进程
- jobs 查看后台进程
- ctrl +z 调到后台进程并停止
- vim test & 调到后台并运行
- fg 1 调到前台，数字是后台进程编号
- bg 4 在后台运行进程4
小实验
ps按占用内存百分比从大到小排列

查找到某一个进程的pid有几种方式
[root@localhost ~]# ps aux | grep vim | grep -v grep
root 72410 7.5 0.2 151888 5440 pts/1 S+ 19:56 0:00 vim test
[root@localhost ~]# pgrep -l vim

[root@localhost ~]# ps -axo pid,command |grep vim | grep -v grep
72410 vim test
[root@localhost ~]# pstree -up | grep vim
| `-sshd(72360)---bash(72368)---vim(72410)
统计出root用户一共运行的进程总数
[root@localhost ~]# ps -axo user,stat |grep root|grep R |wc -l
1
统计出系统当中所有正在正常运行的进程数
[root@localhost ~]# ps -axo stat |grep R |wc -l
1
查看httpd一共启动了几个进程并全部杀死
[root@localhost ~]# pgrep httpd |wc -l
6
[root@localhost ~]# kill `pgrep httpd`
[root@localhost ~]# pgrep httpd |wc -l
0
查看当前用户的所有进程的详细信息
[root@localhost ~]# ps -ux
