环境安装
首先创建一个安装目录
mkdir -p /usr/servers
cd /usr/servers/
接下来安装下面的命令一步一步来
yum install -y readline-devel pcre-devel openssl-devel gcc
wget http://openresty.org/download/ngx_openresty-1.7.7.2.tar.gz
tar -xzvf ngx_openresty-1.7.7.2.tar.gz
cd /usr/servers/ngx_openresty-1.7.7.2/
cd bundle/LuaJIT-2.1-20150120/
make clean && make && make install
ln -sf luajit-2.1.0-alpha /usr/local/bin/luajit
cd /usr/servers/ngx_openresty-1.7.7.2/bundle
wget https://github.com/FRiCKLE/ngx_cache_purge/archive/2.3.tar.gz
tar -xvf 2.3.tar.gz
cd /usr/servers/ngx_openresty-1.7.7.2/bundle
wget https://github.com/yaoweibin/nginx_upstream_check_module/archive/v0.3.0.tar.gz
tar -xvf v0.3.0.tar.gz
cd /usr/servers/ngx_openresty-1.7.7.2
./configure --prefix=/usr/servers --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
make && make install
cd /usr/servers/
到此可以看到这么多的目录
/usr/servers/luajit
/usr/servers/lualib
/usr/servers/nginx
/usr/servers/nginx/sbin/nginx -V
启动nginx:
/usr/servers/nginx/sbin/nginx
nginx+lua开发的hello world
vi /usr/servers/nginx/conf/nginx.conf
在http部分添加:
lua_package_path "/usr/servers/lualib/?.lua;;";
lua_package_cpath "/usr/servers/lualib/?.so;;";
/usr/servers/nginx/conf下,创建一个lua.conf
server {
listen 80;
server_name _;
}
在nginx.conf的http部分添加:
include lua.conf;
验证配置是否正确:
/usr/servers/nginx/sbin/nginx -t
在lua.conf的server部分添加:
location /lua {
default_type 'text/html';
content_by_lua 'ngx.say("hello world")';
}
检测语法是否正确
/usr/servers/nginx/sbin/nginx -t
重新nginx加载配置
/usr/servers/nginx/sbin/nginx -s reload
访问http: http://192.168.219.133/lua
可以在专门的目录下开发
比如创建一个 lua 目录
vi /usr/servers/nginx/conf/lua/test.lua
在test.lua下编写
ngx.say("hello world");
修改lua.conf
location /lua {
default_type 'text/html';
content_by_lua_file conf/lua/test.lua;
}
查看异常日志
tail -f /usr/servers/nginx/logs/error.log
