NGINX+Lua 环境配置

NGINX+Lua 环境配置
- 一、环境装备
- 二、解压安装相应的软件
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

luajit： wget --no-check-certificate https://github.com/openresty/luajit2/archive/refs/tags/v2.1-20210510.tar.gz

lua-nginx-module：wget --no-check-certificate https://github.com/openresty/lua-nginx-module/archive/refs/tags/v0.10.20.tar.gz

lua-resty-core：wget --no-check-certificate https://github.com/openresty/lua-resty-core/archive/refs/tags/v0.1.22.tar.gz

lua-resty-lrucache：wget --no-check-certificate https://github.com/openresty/lua-resty-lrucache/archive/refs/tags/v0.11.tar.gz

nginx-1.17.5：wget --no-check-certificate http://nginx.org/download/nginx-1.17.5.tar.gz

ngx_devel_kit-0.3.1：wget --no-check-certificate https://github.com/vision5/ngx_devel_kit/archive/refs/tags/v0.3.1.tar.gz

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 \

 --conf-path=/etc/nginx/nginx.conf \

 --error-log-path=/var/log/nginx/error.log \

 --http-fastcgi-temp-path=/var/lib/nginx/tmp/fastcgi \

 --http-uwsgi-temp-path=/var/lib/nginx/tmp/uwsgi \

 --http-scgi-temp-path=/var/lib/nginx/tmp/scgi \

 --pid-path=/run/nginx.pid \

 --lock-path=/run/lock/subsys/nginx \

 --user=nginx --group=nginx \

 --with-compat --with-debug --with-file-aio \

 --with-google_perftools_module \

 --with-http_addition_module \

 --with-http_auth_request_module \

 --with-stream=dynamic --with-stream_ssl_module \

 --with-stream_ssl_preread_module --with-threads \

 --with-cc-opt='-O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector-strong --param=ssp-buffer-size=4 -grecord-gcc-switches -specs=/usr/lib/rpm/redhat/redhat-hardened-cc1 -m64 -mtune=generic' \

 --with-ld-opt='-Wl,-z,relro -specs=/usr/lib/rpm/redhat/redhat-hardened-ld -Wl,-E' \

 --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
