OpenResty--------企業級入門實踐篇
前景
前篇介紹了OpenResty核心概念，優點與架構等信息，進行本篇以前建議至少觀看一遍。OpenResty--------企業級理論實踐篇
本篇將進行OpenResty的安裝與編寫第一個應用過程。
注：本篇採用CentOS 7(7.4)系統php

生成編譯與安裝文件
- --prefix=/usr/local/openresty-1.13.6.2 指定安裝目錄爲/usr/local/openresty-1.13.6.2, 默認爲/opt/openresty
- --with-luajit 開啓luajit組件
- --without-http_redis2_module 禁用 http_redis2_module組件
- --with-http_iconv_module 開啓 http_iconv_module組件
[root@localhost openresty-1.13.6.2]# ./configure \ --prefix=/usr/local/openresty-1.13.6.2 \ --with-luajit \ --without-http_redis2_module \ --with-http_iconv_module
編譯
[root@localhost openresty-1.13.6.2]# gmake
安裝
[root@localhost openresty-1.13.6.2]# gmake install
建立軟連接
[root@localhost openresty-1.13.6.2]# ln -s /usr/local/openresty-1.13.6.2 /usr/local/openresty

使用默認的配置文件啓動
[root@localhost openresty-1.13.6.2]# /usr/local/openresty/bin/openresty -p /usr/local/openresty/nginx/
經過瀏覽器訪問測試[測試虛擬機IP爲：192.168.0.254]
訪問成功，OpenResty已經成功返回頁面。html
編寫程序
切換至用戶家目錄
[root@localhost openresty-1.13.6.2]# cd ~
建立工做目錄
[root@localhost ~]# mkdir -vp openresty-test01/{logs,conf}
mkdir: created directory ‘openresty-test01’
mkdir: created directory ‘openresty-test01/logs’
mkdir: created directory ‘openresty-test01/conf’
[root@localhost ~]# tree openresty-test01/
openresty-test01/
├── conf
└── logs
2 directories, 0 files
編寫配置文件
注意： 若是你安裝的是 openresty 1.9.3.1 及如下版本，請使用 content_by_lua 命令代替示例中的 content_by_lua_block。可以使用 nginx/openresty -V 命令查看版本號。linux
[root@localhost ~]# cat openresty-test01/conf/nginx.conf
worker_processes 1; # 設置worker數量
error_log logs/error.log; # 指定錯誤日誌文件路徑
events {
worker_connections 1024; # 單個worker進程最大容許同時創建外部鏈接的數量
}
http {
server {
listen 8888; # 設置監聽端口, 注意系統其它服務是否已佔用該端口
location / {
# lua 代碼塊
content_by_lua_block {
ngx.say("this is lisea no.1 openresty app")
}
}
}
}
運行
[root@localhost ~]# /usr/local/openresty/bin/openresty -p openresty-test01
無報錯就表示運行成功nginx
經過命令測試
[root@localhost ~]# curl 127.0.0.1:8888 this is lisea no.1 openresty app
訪問成功，OpenResty已經成功返回內容。git
經過瀏覽器測試[測試虛擬機IP爲：192.168.0.254, 端口爲配置文件中監聽設置的：8888]
訪問成功，OpenResty已經成功返回內容。github
