脚本任务

监测主机是否联通正常

检查安装操作系统版本是否和需求一致

检查CPU是否满足规格要求

检查内存是否满足规格要求

检查数据磁盘是否满足规格要求

检查操作系统分区目录大小是否满足需求

检查集群主机时间是否一致

0.配置文件准备及脚本变量初始化

编写config.ini存放主机配置文件

[hosts]
10.0.1.10 node01
10.0.1.20 node02
10.0.1.30 node03[root_password]
000000

编写 env-check.sh 取出ip和密码

#!/bin/bash
#
if [ ! -e ./config.ini ];thenecho "config.ini is not exist...please check.."EXIT 1
fiHOSTS_IP=`cat config.ini | sed -n '/\[hosts\]/,/\[.*\]/p' | grep -v "\[.*\]" |grep -v ^$ |grep -v ^# |awk '{print $1}'`ROOT_PATH=`cat config.ini | sed -n '/\[root_password\]/,/\[.*\]/p' | grep -v "\[.*\]" |grep -v ^$ |grep -v ^#`

1.监测主机是否联通正常

function check_host_online
{echo "++++++++++++++++监测主机是否联通正常++++++++++++++++"for host in $HOSTS_IP;doping -w 3 $host &> /dev/nullif [ $? -eq 0 ];thenecho "检测主机 $host 连通性通过"elseecho "检测主机 $host 无法连通"ping_faild_hosts="$ping_faild_hosts $host"fidoneif [[ "$ping_faild_hosts" == "" ]];thenecho "1.使用ping对主机连通性检查，全部通过"elseecho "1.使用ping对主机连通性检查，未全部通过：$ping_faild_hosts"exit 1fi
}

循环遍历主机列表：通过for循环遍历HOSTS_IP变量中包含的所有主机IP地址。

执行ping命令：对每个主机执行ping命令，-w 3参数指定ping操作持续3秒，&> /dev/null将标准输出和标准错误都重定向到/dev/null，即不显示ping命令的输出。

检查ping命令的返回值：使用$?获取上一个命令（即ping命令）的退出状态。如果返回值为0（-eq 0），表示ping命令成功，即主机连通性通过。

打印连通性结果：如果主机连通性通过，则打印"检测主机 $host 连通性通过"；如果不通，则打印"检测主机 $host 无法连通"，并将该主机IP添加到ping_faild_hosts变量中，用于记录失败的主机。

检查是否有主机未通过连通性检查：循环结束后，使用if语句检查ping_faild_hosts变量是否为空。如果为空，表示所有主机的连通性检查都通过了，打印"1.使用ping对主机连通性检查，全部通过"。如果不为空，表示有主机未通过连通性检查，打印"1.使用ping对主机连通性检查，未全部通过：$ping_faild_hosts"，并退出脚本，返回状态为1。

退出脚本：如果检测到有主机连通性失败，脚本将通过exit 1命令退出，并返回状态码1，表示脚本执行失败。

2.检查安装操作系统版本是否和需求一致

先编写检查主机是否能登录

function verify_password
{if [ $# -lt 2 ];thenecho "Usage: verify_password IP root_password"exit 1fisshpass -p$2 ssh -o StrictHostKeyChecking=no -o ConnectTimeout=2 root@$1 "df -h" &> /dev/nullif [ $? -ne 0 ];thenecho "尝试登录ssh主机$1 失败,检查后重试"return 255elsereturn 0fi
}

编写检查操作系统版本是否一致

grep $OS_VERSION /etc/redhat-release

OS_VERSION=`cat config.ini | sed -n '/\[os_version\]/,/\[.*\]/p' | grep -v "\[.*\]" |grep -v ^$ |grep -v ^#`function check_os_version
{for host in $HOSTS_IP;doverify_password $host $ROOT_PASSif [ $? -eq 0 ];thensshpass -p$ROOT_PASS ssh -o StrictHostKeyChecking=no -o ConnectTimeout=2 root@$host "grep $OS_VERSION /etc/redhat-release" &> /dev/nullif [ $? -ne 0 ];thenecho "检查主机$host 版本，与目标不一致,检查不通过"os_failed_hosts="$os_failed_hosts $host"elseecho "检查主机$host 版本，与目标一致,检查通过"fielseos_failed_hosts="$os_failed_hosts $host"fidoneif [[ "$os_failed_hosts" == "" ]];thenecho "2.对主机版本检查，全部通过"elseecho "2.对主机版本检查，未全部通过: $os_failed_hosts"exit 1fi
}

循环遍历主机列表：通过for循环遍历HOSTS_IP变量中包含的所有主机IP地址。

验证密码：对每个主机调用verify_password函数，传入主机IP和root用户的密码$ROOT_PASS，以验证SSH连接的密码是否正确。

检查SSH连接：如果verify_password函数返回状态码0（表示密码验证成功），则继续执行；否则，跳过当前主机。

SSH连接并检查操作系统版本：使用sshpass工具和提供的root用户密码通过SSH连接到主机，并执行grep命令检查/etc/redhat-release文件中是否包含特定的操作系统版本字符串$OS_VERSION。这里使用了-o StrictHostKeyChecking=no选项来禁用严格的主机密钥检查，这在自动化脚本中常用于避免每次连接时的手动确认。

记录检查结果：如果操作系统版本检查未通过（即grep命令返回非0状态码），则打印该主机的检查未通过信息，并将主机IP添加到os_failed_hosts变量中；如果检查通过，则打印该主机的检查通过信息。

汇总检查结果：循环结束后，使用if语句检查os_failed_hosts变量是否为空。如果为空，表示所有主机的操作系统版本检查都通过了，打印"2.对主机版本检查，全部通过"。如果不为空，表示有主机的操作系统版本检查未通过，打印"2.对主机版本检查，未全部通过：$os_faild_hosts"，并退出脚本，返回状态码1。

退出脚本：如果检测到有主机操作系统版本不一致，脚本将通过exit 1命令退出，并返回状态码1，表示脚本执行失败。

3.检查CPU是否满足规格要求

cat /proc/cpuinfo |grep ^processor |sort |uniq |wc -l

CPU_CORES=`cat config.ini | sed -n '/\[cpu_cores\]/,/\[.*\]/p' | grep -v "\[.*\]" |grep -v ^$ |grep -v ^#`
function check_cpu_cores
{for host in $HOSTS_IP;doverify_password $host $ROOT_PASSif [ $? -eq 0 ];thenDST_CPU_CORES=`sshpass -p$ROOT_PASS ssh -o StrictHostKeyChecking=no -o ConnectTimeout=2 root@$host "cat /proc/cpuinfo |grep ^processor |sort |uniq |wc -l"` &> /dev/nullif [ $DST_CPU_CORES -lt $CPU_CORES ];thenecho "检查主机CPU逻辑核心数量,检查不通过"cpu_failed_hosts="$cpu_failed_hosts $host"elseecho "检查主机CPU逻辑核心数量,检查通过"fielsecpu_failed_hosts="$cpu_failed_hosts $host"fidoneif [[ "$cpu_failed_hosts" == "" ]];thenecho "3.对主机cpu检查，全部通过"elseecho "3.对主机cpu检查，未全部通过: $cpu_failed_hosts"exit 1fi

4.检查内存是否满足规格要求

cat /proc/meminfo |grep MemTotal| awk '{print $2}'

TOTAL_MEMORY=`cat config.ini | sed -n '/\[memory_kb\]/,/\[.*\]/p' | grep -v "\[.*\]" |grep -v ^$ |grep -v ^#`
function check_memory
{for host in $HOSTS_IP;doverify_password $host $ROOT_PASSif [ $? -eq 0 ];thenDST_TOTAL_MEMORY=`sshpass -p$ROOT_PASS ssh -o StrictHostKeyChecking=no -o ConnectTimeout=2 root@$host "cat /proc/meminfo |grep MemTotal| awk '{print \\$2}'"` &> /dev/nullif [ $DST_TOTAL_MEMORY -lt $TOTAL_MEMORY ];thenecho "检查主机 $host 内存大小,检查不通过"men_failed_hosts="$men_failed_hosts $host"elseecho "检查主机 $host 内存大小,检查通过"fielsemen_failed_hosts="$men_failed_hosts $host"fidoneif [[ "$men_failed_hosts" == "" ]];thenecho "4.对主机内存检查，全部通过"elseecho "4.对主机内存检查，未全部通过,未通过的主机: $men_failed_hosts"fi
}

5.检查数据磁盘是否满足规格要求

function check_disk_number
{for host in $HOSTS_IP;doverify_password $host $ROOT_PASSALL_DISK_SYMBOLS=`sshpass -p$ROOT_PASS ssh -o StrictHostKeyChecking=no -o ConnectTimeout=2 root@$host "lsscsi |awk '\\$2~/disk/{print \\$8}'"` &> /dev/nullfor d in $ALL_DISK_SYMBOLS;dodf -h | grep "$d" &> /dev/nullif [ $? -eq 0 ];thenDATA_DISK_SYMBOLS=`echo $ALL_DISK_SYMBOLS | sed "s#$d##g"`fidoneDATA_DISK_NUMBER=`echo $DATA_DISK_SYMBOLS | awk '{print NF}'`if [ $DATA_DISK_NUMBER -ge $NUM_OF_DISK ]; thenecho "检查主机 $host 数据盘个数,检查通过"elseecho "检查主机 $host 数据盘个数,检查不通过"disk_failed_hosts="$disk_failed_hosts $host"fidoneif [[ "$disk_failed_hosts" == "" ]];thenecho "5.对主机内存检查，全部通过"elseecho "5.对主机内存检查，未全部通过,未通过的主机: $disk_failed_hosts"fi}

6.检查操作系统分区目录大小是否满足需求

PARTITION_SIZE=`cat config.ini | sed -n '/\[root_partition_size\]/,/\[.*\]/p' | grep -v "\[.*\]" |grep -v ^$ |grep -v ^#`
function check_root_partition_size
{for host in $HOSTS_IP;doverify_password $host $ROOT_PASSif [ $? -eq 0 ];thenROOT_PARTITION_SIZE=`sshpass -p$ROOT_PASS ssh -o StrictHostKeyChecking=no -o ConnectTimeout=2 root@$host "df -h |awk '\\$6==\"/\"{print \\$2}' |sed 's/[^0-9]//g'"` &> /dev/nullif [ $ROOT_PARTITION_SIZE -ge $PARTITION_SIZE ]; thenecho "检查主机 $host 分区大小,检查通过"elseecho "检查主机 $host 分区大小,检查不通过"part_failed_hosts="$part_failed_hosts $host"fielsepart_failed_hosts="$part_failed_hosts $host"fidoneif [[ "$part_failed_hosts" == "" ]];thenecho "6.对主机分区大小,全部通过"elseecho "6.对主机分区大小,未全部通过,未通过的主机: $part_failed_hosts"fi
}

7.检查集群主机时间是否一致

TIME_VALUE=`cat config.ini | sed -n '/\[time_sync_diff\]/,/\[.*\]/p' | grep -v "\[.*\]" |grep -v ^$ |grep -v ^#`
function check_time_sync
{for host in $HOSTS_IP;doLOCAL_TIME=`date "+%Y%m%d%H%M%S"`verify_password $host $ROOT_PASSif [ $? -eq 0 ];thenDST_HOST_TIME=`sshpass -p$ROOT_PASS ssh -o StrictHostKeyChecking=no -o ConnectTimeout=2 root@$host 'date "+%Y%m%d%H%M%S"'` &> /dev/nullTIME_DIFF=`expr $LOCAL_TIME - $DST_HOST_TIME |sed 's/[^0-9]//g'`if [ $TIME_DIFF -lt $TIME_VALUE ];thenecho "检查主机 $host 时间同步通过"elseecho "检查主机 $host 时间同步不通过，时间误差在 $TIME_DIFF"time_failed_hosts="$time_failed_hosts $host"fielsetime_failed_hosts="$time_failed_hosts $host"fidoneif [[ "$time_failed_hosts" == "" ]];thenecho "7.对主机时间检查,全部通过"elseecho "7.对主机时间检查,未全部通过,未通过的主机: $time_failed_hosts"fi
