• 测试Lua环境
• 上面都是经过安装的一些坑之后安装完成的，下面是安装过程中出现的坑

一、环境装备

[root@web01 ~]# cat /etc/redhat-release 
CentOS Linux release 7.7.1908 (Core)

YUM下载安装相关依赖环境
[root@web01 ~]# yum install gcc gcc-c++ prce prce-devel 
> autoconf make automake  
> openssl-devel openssl zlib-devel zlib 
> httpd-tools gperftools -y  

创建下载目录
[root@web01 ~]# cd /opt/;mkdir download 

下载相关软件
v2.1-20210510.tar.gz      #不要下载官网的，要去下载openresty的优化版本 后面会说出现的坑
lua-nginx-module-0.10.20.tar.gz  # 0.10.16 以后都需要3，4两个包
lua-resty-core-0.1.22.tar.gz [必须]
lua-resty-lrucache-0.10.tar.gz [必须]
nginx-1.17.5.tar.gz
ngx_devel_kit-0.3.1.tar.gz

对应下载的网站：https://github.com/openresty

二、解压安装相应的软件

[root@web01 /opt/download]# ls *.tar.gz | xargs -n1 tar xzvf
[root@web01 /opt/download]# cd luajit2-2.1-20210510
make install  PREFIX=/usr/local/LuaJIT
添加环境变量
export LUAJIT_LIB=/usr/local/LuaJIT/lib
export LUAJIT_INC=/usr/local/LuaJIT/include/luajit-2.1
[root@web01 /opt/download]# tail -3f /etc/profile
#Lua
export LUAJIT_LIB=/usr/local/LuaJIT/lib
export LUAJIT_INC=/usr/local/LuaJIT/include/luajit-2.1

安装Lua核心库
lua-resty-core-0.1.21.tar.gz [必须]
lua-resty-lrucache-0.11.tar.gz [必须]

安装在同一个目录下
cd lua-resty-core-0.1.22
make install PREFIX=/usr/local/lua_core
cd ../lua-resty-lrucache-0.11
make install PREFIX=/usr/local/lua_core

编译安装NGINX
[root@web01 /opt/download]# cd nginx-1.17.2/
 ./configure --prefix=/etc/nginx 
 --sbin-path=/usr/sbin/nginx 
 --modules-path=/usr/lib64/nginx/modules

 --add-module=/opt/download/ngx_devel_kit-0.3.1 
 --add-module=/opt/download/lua-nginx-module-0.10.20

加载lua库，加入到ld.so.conf文件
[root@web01 ~]# cat  /etc/ld.so.conf.d/libc.conf
/usr/local/lib
/usr/local/LuaJIT/lib
[root@web01 ~]#  ldconfig

测试Lua环境

主配置文件添加如下：nginx.conf
添加在http模块下
# 指定lua模块路径，多个之间";"分隔，其中";;"表示默认搜索路径，默认到nginx的根目录下找
lua_package_path "/usr/local/Lua_core/lib/lua/?.lua;;";
#指定server配置文件目录
include /etc/nginx/conf.d/*.conf;

server配置如下
[root@web01 /etc/nginx/conf.d]# cat test_lua.conf 
server {
    listen       80;
    server_name 10.4.7.8 www.server1.com;
 
    location /lua {
        set $test "hello,world";
        content_by_lua '
            ngx.header.content_type="text/plain"
            ngx.say(ngx.var.test)';
 
    }
 
}

上面都是经过安装的一些坑之后安装完成的，下面是安装过程中出现的坑

坑一：

nginx: [alert] detected a LuaJIT version which is not OpenResty's; many optimizations will be disabled and performance will be compromised (see https://github.com/openresty/luajit2 for OpenResty's LuaJIT or, even better, consider using the OpenResty releases from https://openresty.org/en/download.html)
# 让我不要用这个luajit版本，可以用openresty提供的luajit优化版本，或者干脆直接用openresty
卸载luajit官网版本，下载openresty提供的luajit优化版本

坑二：

nginx: [alert] failed to load the 'resty.core' module (https://github.com/openresty/lua-resty-core); ensure you are using an OpenResty release from https://openresty.org/en/download.html (reason: module 'resty.core' not found:
        no field package.preload['resty.core']
        no file '../lua-resty-core/lib/resty/core.lua'
        no file '../lua-resty-lrucache/lib/resty/core.lua'
        no file './resty/core.lua'
        no file '/usr/local/LuaJIT/share/luajit-2.0.5/resty/core.lua'
        no file '/usr/local/share/lua/5.1/resty/core.lua'
        no file '/usr/local/share/lua/5.1/resty/core/init.lua'
        no file '/usr/local/LuaJIT/share/lua/5.1/resty/core.lua'
        no file '/usr/local/LuaJIT/share/lua/5.1/resty/core/init.lua'
        no file './resty/core.so'
        no file '/usr/local/lib/lua/5.1/resty/core.so'
        no file '/usr/local/LuaJIT/lib/lua/5.1/resty/core.so'
        no file '/usr/local/lib/lua/5.1/loadall.so'
        no file './resty.so'
        no file '/usr/local/lib/lua/5.1/resty.so'
        no file '/usr/local/LuaJIT/lib/lua/5.1/resty.so'
        no file '/usr/local/lib/lua/5.1/loadall.so') in /etc/nginx/nginx.conf:117
网上查找的结果是说
这个问题到git上面看了 ，https://github.com/openresty/lua-nginx-module/issues/1509
就是在nginx.conf 中的 http{}模块中加入下面这行代码：lua_load_resty_core off;但是检查的时候发现这命令已经废弃

按照上面说安装lua-resty-core和依赖文件lua-resty-lrucache解决问题

lua-resty-core-0.1.22.tar.gz 
lua-resty-lrucache-0.10.tar.gz
