1 windows openresty major command
Considering the ease of operation, it has proposed the establishment of a bat file into the system directory.
Bat script file is as follows, has been through many times use.
openresty startup script
openresty 启动： openresty-start.bat
@echo off
set flag=0
set installPath="E:\tool\openresty-1.15.8.2-win64"
set configPath="E:\tool\openresty-1.15.8.2-win64"
tasklist|find /i "nginx.exe" > nul
if %errorlevel%==0 (
echo "openresty/nginx already running ! "
exit /b
) else set flag=1
cd /d %installPath%
if %flag%==1 (
start nginx.exe -p %configPath%
ping localhost -n 2 > nul
)
tasklist /fi "imagename eq nginx.exe"
tasklist|find /i "nginx.exe" > nul
if %errorlevel%==0 (
echo "openresty/nginx starting succeced!"
)The main changes:
1: installPath for the installation directory;
2: configPath to include web project directory nignx configuration path / config and other paths. Default and the same can be installPath.
openresty stop script
openresty startup script openresty-stop.bat
@echo off
tasklist|find /i "nginx.exe" > nul
if %errorlevel%==0 (
taskkill /f /t /im nginx.exe > nul
echo "openresty/nginx stoped!"
)else echo "openresty/nginx not running!"Examples performed are as follows:
openresty state script
openresty-status.bat
@echo off
tasklist|find /i "nginx.exe" > nul
if %errorlevel%==0 (
tasklist /fi "imagename eq nginx.exe"
echo "openresty/nginx is running!"
exit /b
) else echo "openresty/nginx is stoped!" openresty 重启脚本
openresty-restart.bat
@echo off
call openresty-stop.bat
call openresty-start.bat可以提前从疯狂创客圈的网盘，下载以上的脚本。
2 windows openresty 的安装
前面提到，OpenResty 的依赖库有： perl 5.6.1+, libreadline, libpcre, libssl。
2.1 下载安装 openresty
打开openresty的中文官网，下载网站为：http://openresty.org/cn/download.html 。具体如下图
下载合适的版本， 然后解压即可。
解压到要安装的目录，这里我选择e:/tool目录，你可以根据自己的喜好选择位置。
使用 openresty-start.bat 启动，然后，在浏览器的地址栏输入 http://localhost:80/，理论上，会有 nginx 的欢迎页面。
但是，也有可能启动失败，如下图：
在浏览器的地址栏输入 localhost，加载 nginx 的欢迎页面。成功加载说明 nginx 正在运行。如下图：
可能的原因是，缺少依赖包。
2.2：需要安装 perl
前面提到，OpenResty 的依赖库有： perl 5.6.1+, libreadline, libpcre, libssl。
首先要安装Perl。 Perl 是 Practical Extraction and Report Language 的缩写，可翻译为 "实用报表提取语言"。Perl 是高级、通用、直译式、动态的程序语言。
如果没有安装perl，启动会报如下错误：
PS E:\tool\openresty-1.15.8.2-win64\conf> resty.bat
'perl' 不是内部或外部命令，也不是可运行的程序
或批处理文件。
You do not have Perl in your PATH.
PS E:\tool\openresty-1.15.8.2-win64\conf>打开浏览器在搜索栏里面输入: http://strawberryperl.com/ 进入到 perl 官网进行下
双击打开下载好的 perl安装文件，安装到自己喜欢的目录。这里使用了 e:/tool
使用快捷键 win + r 打开 windows 应用程序, 输入 cmd 来查看是否安装成功
In which enter cmd: perl -version View installed version
PS E:\tool\openresty-1.15.8.2-win64\conf> perl -version
This is perl 5, version 30, subversion 1 (v5.30.1) built for MSWin32-x64-multi-thread

this system using "man perl" or "perldoc perl". If you have access to the
Internet, point your browser at http://www.perl.org/, the Perl Home Page.
Note: If you can not already open before installing the cmd window, after installation, you need to open a new window cmd
3 officially launched openresty
3.1 modify the script and start
Openresty talked about earlier start: openresty-start.bat
Modify the path in which to install their own path, and then start
Script, the tasklist /fi "imagename eq nginx.exe"output nginx process, one of which is the master process, the other is a worker process
View 3.2 browser interface
Go to http input in the browser address bar: // localhost: 80 /, you can see the results after a successful start:
