nginx安装lua模块实现高并发

nginx安装lua扩展模块

1.下载安装LuaJIT-2.0.4.tar.gz

wget -c http://luajit.org/download/LuaJIT-2.0.4.tar.gz

tar xzvf LuaJIT-2.0.4.tar.gz

cd LuaJIT-2.0.4

make install PREFIX=/usr/local/luajit

#注意环境变量!

export LUAJIT_LIB=/usr/local/luajit/lib

export LUAJIT_INC=/usr/local/luajit/include/luajit-2.0

2.下载解压ngx_devel_kit

wget https://github.com/simpl/ngx_devel_kit/archive/v0.3.0.tar.gz

tar -xzvf v0.3.0.tar.gz

3.下载解压lua-nginx-module

wget https://github.com/openresty/lua-nginx-module/archive/v0.10.8.tar.gz

tar -xzvf v0.10.8.tar.gz

4.下载安装nginx-1.10.3.tar.gz

wget http://nginx.org/download/nginx-1.10.3.tar.gz

tar -xzvf nginx-1.10.3.tar.gz

cd nginx-1.10.3

./configure --add-module=/opt/soft/ngx_devel_kit-0.3.0 --add-module=/opt/soft/lua-nginx-module-0.10.8

#注意ngx_devel_kit和lua-nginx-module以实际解压路径为准

make -j2

make install

注：报错gcc需要安装，可以执行

yum install -y gcc g++ gcc-c++

依赖报错，可以执行

yum -y install zlib zlib-devel openssl openssl--devel pcre pcre-devel

5.验证

#将nginx做成命令

ln -s /usr/local/nginx/sbin/nginx /usr/bin/nginx

cd /usr/local/nginx/conf/

vi nginx.conf

#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");

#启动nginx（已经做了软连接了，可以在任何目录启动）

nginx

注：

报错nginx: error while loading shared libraries: libluajit-5.1.so.2: cannot open shared object file: No such file or directory 可以执行

ln -s /usr/local/luajit/lib/libluajit-5.1.so.2 /lib64/libluajit-5.1.so.2

具体source的路径已实际安装路径为准

window平台开发代码部署到Linux服务器

由于两个平台的不同导致脚本文件的编码类型不一致部署后会出现一些诡异的问题
