Nginx整合Lua步骤

以你之姓@ 2022-05-24 05:37 232阅读 1赞

**1、Nginx:**

yum install gcc-c++
    yum install -y pcre pcre-devel
    yum install -y zlib zlib-devel
    yum install -y openssl openssl-devel
    
    wget -c https://nginx.org/download/nginx-1.10.1.tar.gz
    
    tar -xzf nginx-1.10.1.tar.gz

**2.下载安装LuaJIT-2.0.4.tar.gz**

wget -c http://luajit.org/download/LuaJIT-2.0.4.tar.gz
    tar -zxf LuaJIT-2.0.4.tar.gz
    cd LuaJIT-2.0.4
    
    make install PREFIX=/usr/local/luajit

环境变量/etc/profile文件中增加环境变量，并执行source /etc/profile

export LUAJIT_LIB=/usr/local/luajit/lib
    export LUAJIT_INC=/usr/local/luajit/include/luajit-2.0
    export LD_LIBRARY_PATH=/usr/local/luajit/lib:$LD_LIBRARY_PATH

**3.下载解压ngx\_devel\_kit**

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

**4.下载解压lua-nginx-module**

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

**5、Nginx解压包下**

./configure --add-module=/usr/local/ngx_devel_kit-0.3.0 --add-module=/usr/local/lua-nginx-module-0.10.8
    make -j2
    make install
    
    将nginx做成命令  ln -s /usr/local/nginx/sbin/nginx /usr/bin/nginx
    启动：nginx  重启：nginx -s reload  关闭：nginx -s stop

**错误1：**  
nginx: error while loading shared libraries: libluajit-5.1.so.2: cannot open shared object file: No such file or

directory

解决：  
环境变量/etc/profile文件中增加环境变量，并执行source /etc/profile

export LD_LIBRARY_PATH=/usr/local/luajit/lib:$LD_LIBRARY_PATH

**错误2：**  
nginx: \[error\] open() “/usr/local/nginx/logs/nginx.pid” failed (2: No such file or directory)

解决：  
进入nginx安装目录下，使用nginx -c的参数指定nginx.conf文件的位置

/usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf

测试：

#直接写nginx-lua脚本语言方式
            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; #nginx安装目录conf下
            }
    
            #test.lua中的内容
            ngx.say("hello, world")
