sh's Introduction

sh

auto start php project

#下面是auto_build.sh文件内容

 #!/bin/bash
 ## build src
 echo $1 #project git url
 webroot="/home/project/"
 giturl=$1
 port=$2

 #1、build direct
 dir=$webroot"test"
 if [ ! -d $dir ]; then
 mkdir $dir
 else  
 d="`date +%Y%m%d%H%M%S`"
 cp -r $dir $dir"_"$d
 rm -rf $dir
 mkdir $dir
 fi
 cd $dir

 #2、download project
 #git clone "$1"

 #3、get project name
 last=${giturl##*/}
 project_name=${last%.*}
 echo $project_name

 #4、set nginx config for the project
 ngx_conf=$project_name".conf"
 echo $ngx_conf
 new_conf=$webroot$ngx_conf
 #5、如果没有创建过配置文件
 if [ ! -d $new_conf ]; then
 #创建配置文件
 cp $webroot"/create.conf" $new_conf
 #替换文件内容
 project_url=$webroot$project_name
 sed -i "s/@port@/$port/g" $new_conf 
 sed -i "s/@project_name@/"${project_name}"/g" $new_conf 
 sed -i "s/@server_name@/www.$project_name.com/g" $new_conf 
 fi

#linux crontab每秒执行的最简单实现方法

 近要做一个发短信订阅的计划，每3秒执行一次

 * * * * * for i in {0..59}; do curl http://localhost/data/sms_data.php && sleep 3; done;

 每秒执行如下：
 
 * * * * * for i in {0..59}; do curl http://localhost/data/sms_data.php && sleep 1; done;

 每15秒执行一次：

 * * * * * for i in 0 1 2; do curl http://localhost/data/sms_data.php & sleep 15; done;
