1.前期需要的安装包下载地址:
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/v0.10.19rc1.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-1.20.2:wget --no-check-certificate http://nginx.org/download/nginx-1.20.2.tar.gz
ngx_devel_kit-0.3.0:wget --no-check-certificate https://github.com/vision5/ngx_devel_kit/archive/refs/tags/v0.3.0.tar.gz
备注:
luajit #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-resty-core和lua-resty-lrucache是必须的包,0.10.16 以后都需要这两个包
2.安装(app用户安装):
#安装包放到这个目录下面
mkdir /app/nginx_plug
tar xf v2.1-20210510.tar.gz
cd luajit2-2.1-20210510
make install PREFIX=/app/nginx_plug/LuaJIT
#添加环境变量
export LUAJIT_LIB=/app/nginx_plug/LuaJIT/lib
export LUAJIT_INC=/app/nginx_plug/LuaJIT/include/luajit-2.1
[app@web01 /opt/download]$ tail -3f /etc/profile
#Lua
export LUAJIT_LIB=//app/nginx_plug/LuaJIT/lib
export LUAJIT_INC=/app/nginx_plug/LuaJIT/include/luajit-2.1
source /etc/profile
#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= /etc/profile/lua_core
cd ../lua-resty-lrucache-0.11
make install PREFIX= /etc/profile/lua_core
#解压v0.3.0.tar.gz和v0.10.19rc1.tar.gz
#nginx安装
cd nginx-1.20.2/
./configure --prefix=/app/nginx20 --pid-path=/app/nginx20/logs/nginx.pid --with-http_ssl_module --with-http_v2_module --with-http_dav_module --with-http_flv_module --with-http_realip_module --with-http_addition_module --with-http_xslt_module --with-http_stub_status_module --with-http_sub_module --with-http_random_index_module --with-http_degradation_module --with-http_secure_link_module --with-http_gzip_static_module --http-client-body-temp-path=/app/nginx20/client_body --http-proxy-temp-path=/app/nginx20/proxy --http-fastcgi-temp-path=/app/nginx20/fastcgi --http-uwsgi-temp-path=/app/nginx20/uwsgi --http-scgi-temp-path=/app/nginx20/scgi --with-stream --with-ld-opt=-Wl,-E --add-module=/app/nginx_plug/lua-nginx-module-0.10.19rc1/ --add-module=/app/nginx_plug/ngx_devel_kit-0.3.0
make
make install
#加载lua库,加入到ld.so.conf文件
[root@web01 ~]# echo "/app/nginx_plug/LuaJIT/lib" >> /etc/ld.so.conf
[root@web01 ~]# ldconfig
#启动nginx
/app/nginx20/sbin/nginx -c /app/nginx20/conf/nginx.conf
3.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
报错截图:配置文件没有问题,但是起不来
1)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
对应luajit-----#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
2)报错信息:
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 './resty/core.lua'
no file '/usr/local/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 './resty/core.so'
no file '/usr/local/lib/lua/5.1/resty/core.so'

no file '/usr/local/lib/lua/5.1/resty.so'
no file '/usr/local/lib/lua/5.1/loadall.so') in /app/nginx20/conf/nginx.conf:441
解决方法:
1)这个问题到git上面看了,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,显然这样不行,造成这样的原因是:nginx_lua 0.10.16之后的版本是需要lua_resty_core库的,需要需要在安装lua-resty-core-0.1.21和lua-resty-lrucache-0.11(安装参考上面)
2)安装完成之后依然还是报错:
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:
解决方法:创建超链接
ln -s /app/nginx_plug/lua_core/lib/lua/resty /app/nginx_plug/LuaJIT/share/luajit-2.1.0-beta3/resty
3)再重启发现服务可以启动了
