openresty (nginx + lua)
这里部署一个 双层的nginx
部署 openresty
mkdir -p /usr/servers/distribution_nginx
cd /usr/servers/distribution_nginx
上传 openresty 的tar.gz包 下载地址：http://openresty.org/cn/download.html
tar -zxvf openresty-1.13.6.1.tar.gz
cd openresty-1.13.6.1/
一、安装lua
cd bundle/LuaJIT-2.1-20171103/
make clean && make && make install
如果安装中出现以下错误：
gcc: Command not found
解决：
yum -y install gcc automake autoconf libtool make
再重新安装lua
二、下载ngx_cache_purge模块，该模块用于nginx缓存
cd /usr/servers/distribution_nginx/openresty-1.13.6.1/bundle
wget https://github.com/FRiCKLE/ngx_cache_purge/archive/2.3.tar.gz
tar -xvf 2.3.tar.gz
三、下载nginx_upstream_check_module模块，该模块用于ustream健康检查
wget https://github.com/yaoweibin/nginx_upstream_check_module/archive/v0.3.0.tar.gz
tar -xvf v0.3.0.tar.gz
安装 openresty
./configure --prefix=/usr/servers/distribution_nginx/ --with-http_realip_module --with-pcre --with-luajit --add-module=./bundle/ngx_cache_purge-2.3/ --add-module=./bundle/nginx_upstream_check_module-0.3.0/ -j2
会报错，根据错误提示，安装以下的库
yum install gcc
yum install -y pcre pcre-devel
yum install -y openssl openssl-devel
yum install -y zlib zlib-devel (如果安装过，就不用安装)
执行成功过后执行
make && make install
检查安装是否成功
cd /usr/servers/distribution_nginx/nginx/sbin
./nginx -v 查看版本
./nginx 启动
出现以下内容：
ps -ef| grep nginx
root 14827 1 0 14:07 ? 00:00:00 nginx: master process ./nginx
nobody 14828 14827 0 14:07 ? 00:00:00 nginx: worker process
--------------------------------------------------------------------------------------------------------------------------------------------------------------
nginx + lua的 hello world
cd /usr/servers/distribution_nginx/nginx/
cd conf
vi lua.conf
添加如下内容
server {
listen 80;
server_name _;
location /lua {
default_type 'text/html';
content_by_lua 'ngx.say("hello world");
}
}
vi nginx.conf
在http 部分添加：
http {
lua_package_path "/usr/servers/lualib/?.lua;;";
lua_package_cpath "/usr/servers/lualib/?.so;;";
include lua.conf;
include mime.types;
default_type application/octet-stream;
.
.
.
验证配置是否正确：
cd ../sbin
./nginx -t
看到
nginx: the configuration file /usr/servers/distribution_nginx//nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/servers/distribution_nginx//nginx/conf/nginx.conf test is successful
重新加载
./nginx -s reload
