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
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

[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 reload6. 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
