1. 安装依赖的软件包
/usr/bin/env: perl: No such file or directory出现这种错误可能是没有安装prel
yum install readline-devel pcre-devel openssl-devel gcc
2. 安装openresty
-- 1. 下载openresty源码： http://openresty.org/cn/download.html
$ wget https://openresty.org/download/openresty-1.9.7.4.tar.gz
-- 2. 解压tar包
$ tar xzvf openresty-1.9.7.4.tar.gz
-- 3. 配置编译选项，可以根据你的实际情况增加、减少相应的模块
$ ./configure --prefix=/opt/openresty --with-luajit --without-http_redis2_module --with-http_iconv_module
-- 4. 编译并安装
$ make
$ make install
3. HelloWorld
-- 1. 修改配置文件如下：
$ cat /opt/openresty/nginx/conf/nginx.conf
worker_processes 1;
error_log logs/error.log info;
events {
worker_connections 1024;
}
http {
server {
listen 8003;
location / {
content_by_lua 'ngx.say("hello world.")';
}
}
}
-- 2. 启动nginx
$ /opt/openresty/nginx/sbin/nginx
-- 3. 检查nginx
$ curl http://127.0.0.1:8003/
hello world.
4. 性能测试
-- 1. 安装压力测试工具
$ yum install httpd-tools
-- 2. 测试
$ ab -c10 -n50000 http://localhost:8003/
