Nginx安装配置Lua支持

Nginx中配置lua脚本，访问url总是提示404

总结

Nginx安装配置Lua支持

默认情况下Nginx不支持Lua模块，需要安装LuaJIT解释器，并且重新编译Nginx，或者可使用国人开发的openrestry

需要的模块：LuaJIT,Ngx_devel和lua-nginx-module

Luajit官网：https://luajit.org

1. 环境准备

[root@nginx_lua ~]# yum install -y gcc gcc-c++ make pcre-devel zlib-devel openssl-devel

2. 下载最新的luajit和ngx_devel_kit以及lua-nginx-module解压

[root@nginx_lua ~]# mkdir -p /soft/src 
[root@nginx_lua ~]# cd /soft/src/
wget https://luajit.org/download/LuaJIT-2.0.4.tar.gz
wget https://github.com/simpl/ngx_devel_kit/archive/v0.2.19.tar.gz
wget https://github.com/openresty/lua-nginx-module/archive/v0.10.13.tar.gz

3. 解压ngx_devel_kit以及lua-nginx-module

[root@nginx_lua src]# tar xf v0.2.19.tar.gz
[root@nginx_lua src]# tar xf v0.10.13.tar.gz

4. 编译安装LuaJIT，即Lua及时编译器

[root@nginx_lua src]# tar xf LuaJIT-2.0.4.tar.gz
[root@nginx_lua src]# cd LuaJIT-2.0.4/
[root@nginx_lua LuaJIT-2.0.4]# make && make install

5. 编译安装Nginx

[root@nginx_lua src]# wget http://nginx.org/download/nginx-1.14.2.tar.gz
[root@nginx_lua src]# tar xf nginx-1.14.2.tar.gz
[root@nginx_lua src]# cd nginx-1.14.2
[root@nginx_lua nginx-1.14.2]# ./configure --prefix=/soft/nginx --with-http_ssl_module --with-http_stub_status_module --with-http_dav_module --with-file-aio --with-http_dav_module --add-module=../ngx_devel_kit-0.2.19/ --add-module=../lua-nginx-module-0.10.13/
[root@nginx_lua nginx-1.14.2]# make && make install
[root@nginx_lua nginx-1.14.2]# ln -s /soft/nginx/sbin/nginx /usr/bin/nginx
[root@nginx_lua conf]# vim nginx.conf  #简单配置写nginx测试Nginx是否已经支持Lua(lua指令方式)
...
server {
 location /test_lua {
                default_type text/html;
                content_by_lua_block {
                        ngx.say("Hello Lua!") 
                }
        }
...
}
#lua指令方式
#在server 中添加一个localtion
location /hello {
            default_type 'text/plain';
            content_by_lua 'ngx.say("hello, lua")';
        }
#lua文件方式
#在server 中添加一个localtion
location /lua {
    default_type 'text/html';
    content_by_lua_file conf/lua/test.lua; #相对于nginx安装目录
}
#test.lua文件内容
ngx.say("hello world");
//建立软连接，如果不建立软链接，则会出现share object错误
[root@nginx_lua conf]# nginx -t
/soft/nginx/sbin/nginx: error while loading shared libraries: libluajit-5.1.so.2: cannot open shared object file: No such file or directory
[root@nginx_lua conf]# 
[root@nginx_lua lib64]# ln -s /usr/local/lib/libluajit-5.1.so.2 /lib64/libluajit-5.1.so.2
[root@nginx_lua lib64]# ll libluajit-5.1.so.2
lrwxrwxrwx 1 root root 33 Dec 21 20:52 libluajit-5.1.so.2 -> /usr/local/lib/libluajit-5.1.so.2
[root@nginx_lua lib64]#
#//加载lua库，加入到ld.so.conf文件（暂时不执行这一步）
#[root@nginx_lua nginx-1.14.2]# echo "/usr/local/LuaJIT/lib" >> /etc/ld.so.conf
[root@nginx_lua conf]# nginx -t
nginx: the configuration file /soft/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /soft/nginx/conf/nginx.conf test is successful
[root@nginx_lua conf]# nginx -s reload

6. 测试安装Lua成功

Nginx中配置lua脚本，访问url总是提示404

然后进入nginx的error.log中发现了以下错误日志

2022/06/09 18:31:46 [error] 24475#24475: *5 failed to load external Lua file "/root/lua/68/update_content.lua": cannot open /root/lua/68/update_content.lua: Permission denied, client: 112.4.254.104, server: localhost, request: "GET /api/update_content HTTP/1.1", host: "your host"

然后在nginx.conf中配置

user root root;

再重启nginx即可

总结

以上为个人经验，希望能给大家一个参考，也希望大家多多支持软件开发网。
