根据进程名pid
以及用户查看相关信息 https://mp.weixin.qq.com/s/zdN04sNkdLFlDd_Pls8ZeA
一. 根据PID
过滤进程所有信息 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 #! /bin/bash read -p "请输入要查询的PID: " Pn=`ps -aux| awk '$2~/^' $P '$/{print $11}' |wc -l` if [ $n -eq 0 ];then echo "该PID不存在!!" exit fi echo "--------------------------------" echo "进程PID: $P " echo "进程命令:`ps -aux| awk '$2 ~/^'$P '$/{print $11 }'`" echo "进程所属用户: `ps -aux| awk '$2 ~/^'$P '$/{print $1 }'`" echo "CPU占用率:`ps -aux| awk '$2 ~/^'$P '$/{print $3 }'`%" echo "内存占用率:`ps -aux| awk '$2 ~/^'$P '$/{print $4 }'`%" echo "进程开始运行的时刻:`ps -aux| awk '$2 ~/^'$P '$/{print $9 }'`" echo "进程运行的时间:`ps -aux| awk '$2 ~/^'$P '$/{print $10 }'`" echo "进程状态:`ps -aux| awk '$2 ~/^'$P '$/{print $8 }'`" echo "进程虚拟内存:`ps -aux| awk '$2 ~/^'$P '$/{print $5 }'`" echo "进程共享内存:`ps -aux| awk '$2 ~/^'$P '$/{print $6 }'`" echo "--------------------------------"
二、根据进程名过滤进程信息 会显示出该进程名包含的所有线程
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 #! /bin/bash read -p "请输入要查询的进程名:" NAMEN=`ps -aux | grep $NAME | grep -v grep | wc -l` if [ $N -le 0 ];then echo "该进程名没有运行!" fi i=1 while [ $N -gt 0 ]do echo "进程PID: `ps -aux | grep $NAME | grep -v grep | awk 'NR=='$i '{print $0 }'| awk '{print $2 }'`" echo "进程命令:`ps -aux | grep $NAME | grep -v grep | awk 'NR=='$i '{print $0 }'| awk '{print $11 }'`" echo "进程所属用户: `ps -aux | grep $NAME | grep -v grep | awk 'NR=='$i '{print $0 }'| awk '{print $1 }'`" echo "CPU占用率:`ps -aux | grep $NAME | grep -v grep | awk 'NR=='$i '{print $0 }'| awk '{print $3 }'`%" echo "内存占用率:`ps -aux | grep $NAME | grep -v grep | awk 'NR=='$i '{print $0 }'| awk '{print $4 }'`%" echo "进程开始运行的时刻:`ps -aux | grep $NAME | grep -v grep | awk 'NR=='$i '{print $0 }'| awk '{print $9 }'`" echo "进程运行的时间:` ps -aux | grep $NAME | grep -v grep | awk 'NR=='$i '{print $0 }'| awk '{print $11 }'`" echo "进程状态:`ps -aux | grep $NAME | grep -v grep | awk 'NR=='$i '{print $0 }'| awk '{print $8 }'`" echo "进程虚拟内存:`ps -aux | grep $NAME | grep -v grep | awk 'NR=='$i '{print $0 }'| awk '{print $5 }'`" echo "进程共享内存:`ps -aux | grep $NAME | grep -v grep | awk 'NR=='$i '{print $0 }'| awk '{print $6 }'`" echo "***************************************************************" let N-- i++ done
三、根据用户名查询该用户的相关信息 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 #! /bin/bash read -p "请输入要查询的用户名:" Aecho "------------------------------" n=`cat /etc/passwd | awk -F: '$1~/^' $A '$/{print}' | wc -l` if [ $n -eq 0 ];then echo "该用户不存在" echo "------------------------------" else echo "该用户的用户名:$A " echo "该用户的UID:`cat /etc/passwd | awk -F: '$1 ~/^'$A '$/{print}'|awk -F: '{print $3 }'`" echo "该用户的组为:`id $A | awk {'print $3 '}`" echo "该用户的GID为:`cat /etc/passwd | awk -F: '$1 ~/^'$A '$/{print}'|awk -F: '{print $4 }'`" echo "该用户的家目录为:`cat /etc/passwd | awk -F: '$1 ~/^'$A '$/{print}'|awk -F: '{print $6 }'`" Login=`cat /etc/passwd | awk -F: '$1~/^' $A '$/{print}' |awk -F: '{print $7}' ` if [ $Login == "/bin/bash" ];then echo "该用户有登录系统的权限!!" echo "------------------------------" elif [ $Login == "/sbin/nologin" ];then echo "该用户没有登录系统的权限!!" echo "------------------------------" fi fi
四、加固系统的一些配置( 未测试 ) 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 #! /bin/bash read -p "设置密码最多可多少天不修改:" Aread -p "设置密码修改之间最小的天数:" Bread -p "设置密码最短的长度:" Cread -p "设置密码失效前多少天通知用户:" Dsed -i '/^PASS_MAX_DAYS/c\PASS_MAX_DAYS ' $A '' /etc/login.defs sed -i '/^PASS_MIN_DAYS/c\PASS_MIN_DAYS ' $B '' /etc/login.defs sed -i '/^PASS_MIN_LEN/c\PASS_MIN_LEN ' $C '' /etc/login.defs sed -i '/^PASS_WARN_AGE/c\PASS_WARN_AGE ' $D '' /etc/login.defs echo "已对密码进行加固,新用户不得和旧密码相同,且新密码必须同时包含数字、小写字母,大写字母!!" sed -i '/pam_pwquality.so/c\password requisite pam_pwquality.so try_first_pass local_users_only retry=3 authtok_type= difok=1 minlen=8 ucredit=-1 lcredit=-1 dcredit=-1' /etc/pam.d/system-auth echo "已对密码进行加固,如果输入错误密码超过3次,则锁定账户!!" n=`cat /etc/pam.d/sshd | grep "auth required pam_tally2.so " |wc -l` if [ $n -eq 0 ];then sed -i '/%PAM-1.0/a\auth required pam_tally2.so deny=3 unlock_time=150 even_deny_root root_unlock_time300' /etc/pam.d/sshd fi echo "已设置禁止root用户远程登录!!" sed -i '/PermitRootLogin/c\PermitRootLogin no' /etc/ssh/sshd_config read -p "设置历史命令保存条数:" Eread -p "设置账户自动注销时间:" Fsed -i '/^HISTSIZE/c\HISTSIZE=' $E '' /etc/profile sed -i '/^HISTSIZE/a\TMOUT=' $F '' /etc/profile echo "已设置只允许wheel组的用户可以使用su命令切换到root用户!" sed -i '/pam_wheel.so use_uid/c\auth required pam_wheel.so use_uid ' /etc/pam.d/su n=`cat /etc/login.defs | grep SU_WHEEL_ONLY | wc -l` if [ $n -eq 0 ];then echo SU_WHEEL_ONLY yes >> /etc/login.defsfi echo "即将对系统中的账户进行检查...." echo "系统中有登录权限的用户有:" awk -F: '($7=="/bin/bash"){print $1}' /etc/passwd echo "********************************************" echo "系统中UID=0的用户有:" awk -F: '($3=="0"){print $1}' /etc/passwd echo "********************************************" N=`awk -F: '($2==""){print $1}' /etc/shadow|wc -l` echo "系统中空密码用户有:$N " if [ $N -eq 0 ];then echo "恭喜你,系统中无空密码用户!!" echo "********************************************" else i=1 while [ $N -gt 0 ] do None=`awk -F: '($2==""){print $1}' /etc/shadow|awk 'NR==' $i '{print}' ` echo "------------------------" echo $None echo "必须为空用户设置密码!!" passwd $None let N-- done M=`awk -F: '($2==""){print $1}' /etc/shadow|wc -l` if [ $M -eq 0 ];then echo "恭喜,系统中已经没有空密码用户了!" else echo "系统中还存在空密码用户:$M " fi fi echo "即将对系统中重要文件进行锁定,锁定后将无法添加删除用户和组" read -p "警告:此脚本运行后将无法添加删除用户和组!!确定输入Y,取消输入N;Y/N:" icase $i in [Y,y]) chattr +i /etc/passwd chattr +i /etc/shadow chattr +i /etc/group chattr +i /etc/gshadow echo "锁定成功!" ;; [N,n]) chattr -i /etc/passwd chattr -i /etc/shadow chattr -i /etc/group chattr -i /etc/gshadow echo "取消锁定成功!!" ;; *) echo "请输入Y/y or N/n" esac
