进程自动重启 以nginx 和 php-fpm为例

#!/bin/bash
process='nginx php-fpm'
bin="/etc/init.d"
log="/data/logs/check_process.log"
data=$(date +"%Y-%m-%d %H:%M:%S")
for i in $process
do
#echo $i
exists=`ps -ef|grep "$i"|grep -v grep|wc -l`
if [ "$exists" -eq "0" ]; then
${bin}/${i} restart
    if [ "$?" -eq "0" ]; then
        echo "${data} : ${i} ------------------restart sucesses------------------" >> $log
    else
        echo "${data} : ${i} ***-------------------------------------------------------------restart failed***" >> $log
    fi
else
echo "${data} : ${i} already running" >> $log
fi
done
