ngx_openresty编译安装部署详解

软件简介:

OpenResty (也称为 ngx_openresty)是一个全功能的 Web 应用服务器,它打包了标准的 Nginx 核心,很多的常用的第三方模块,以及它们的大多数依赖项。

OpenResty 通过汇聚各种设计精良的 Nginx 模块,

从而将 Nginx 有效的变成一个强大的 Web 应用服务器,

这样, Web 开发人员可以使用 Lua 脚本语言调动 Nginx 支持的各种C以及Lua 模块,

快速构造出足以胜任 10K+ 并发连接响应的超高性能Web 应用系统.


OpenResty 的目标是让你的Web服务直接跑在 Nginx 服务内部,

充分利用 Nginx 的非阻塞 I/O 模型,

不仅仅对 HTTP 客户端请求,甚至于对远程后端诸如

MySQL,PostgreSQL,~Memcaches 以及 ~Redis 等都进行一致的高性能响

1.建立nginx运行用户和程序目录:

groupadd www

useradd -s /sbin/nologin -g www www

mkdir -p /usr/local/nginx

mkdir -p /usr/local/pcre


2.软件包下载(目前最稳定版本):

wget http://jaist.dl.sourceforge.net/project/pcre/pcre/8.32/pcre-8.32.zip

wget http://agentzh.org/misc/nginx/ngx_openresty-1.4.3.6.tar.gz


3.软件安装

3.1:安装pcre-8.32


mkdir -p /usr/local/pcre

unzip pcre-8.32.zip

cd pcre-8.32

./configure --prefix=/usr/local/pcre --enable-utf8 --enable-pcregrep-libbz2 --enable-pcregrep-libz

make && make install


3.2:安装ngx_openresty


tar -xvf ngx_openresty-1.4.3.6.tar.gz

cd ngx_openresty-1.4.3.6

./configure --user=www --group=www --prefix=/usr/local/ --with-pcre --user=www --group=www --with-luajit --with-file-aio --with-http_ssl_module  --with-http_gzip_static_module --with-http_stub_status_module  --with-pcre=/workspace/pcre-8.32 --with-cc-opt=' -O3'

gmake

gmake install

/etc/init.d/nginx reload


4.nginx调用lua测试配置文件


worker_processes  1;

events {

  worker_connections  1024;

}

http {

  include       mime.types;

  default_type  application/octet-stream;

  #log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '

  #                  '$status $body_bytes_sent "$http_referer" '

  #                  '"$http_user_agent" "$http_x_forwarded_for"';

  #access_log  logs/access.log  main;

  sendfile        on;

  #tcp_nopush     on;

  #keepalive_timeout  0;

  keepalive_timeout  65;

  #gzip  on;

  server {

      listen       80;

      server_name  localhost;

      #access_log  logs/host.access.log  main;

location /echo {

default_type 'text/plain';

echo 'hello echo';

}


location /lua {

default_type 'text/plain';

  content_by_lua 'ngx.say("hello, lua")';

}


}  


   }


5.nginx 启动文件内容


#! /bin/sh

# chkconfig: 2345 55 25

# Description: Startup script for nginx webserver on Debian. Place in /etc/init.d and

# run 'update-rc.d -f nginx defaults', or use the appropriate command on your

# distro. For CentOS/Redhat run: 'chkconfig --add nginx'


### BEGIN INIT INFO

# Provides:          nginx

# Required-Start:    $all

# Required-Stop:     $all

# Default-Start:     2 3 4 5

# Default-Stop:      0 1 6

# Short-Description: starts the nginx web server

# Description:       starts nginx using start-stop-daemon

### END INIT INFO

DAEMON=/usr/local/nginx/sbin/$NAME

CONFIGFILE=/usr/local/nginx/conf/$NAME.conf

set -e

[ -x "$DAEMON" ] || exit 0


do_start() {

$DAEMON -c $CONFIGFILE || echo -n "nginx already running"

}


do_stop() {

kill -INT `cat $PIDFILE` || echo -n "nginx not running"

}


do_reload() {

kill -HUP `cat $PIDFILE` || echo -n "nginx can't reload"

}


case "$1" in

start)

echo -n "Starting $DESC: $NAME"

do_start

echo "."

echo -n "Stopping $DESC: $NAME"

do_stop

do_stop

do_start

echo "."

;;

*)

echo "Usage: $SCRIPTNAME {start|stop|reload|restart}" >&2

exit 3

;;

esac


exit 0


6,安装报错:

6.1

[root@localhost conf]# /usr/local/nginx/sbin/nginx -t  

/usr/local/nginx/sbin/nginx: error while loading shared libraries: libpcre.so.1: cannot open shared object file: No such file or directory  


解决方法:在/lib中创建一个symbol link到/usr/local/lib/libpcre.so.1


[root@localhost conf]# ln -s /usr/local/lib/libpcre.so.1 /lib


若出现如下信息,则表示配置正确,否则需按错误提示进行配置文件更正


nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok

nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful



6.2、启动Nginx服务


#/usr/local/nginx/sbin/nginx


出现告警信息:


nginx: [warn] the "log_format" directive may be used only on "http" level in /usr/local/nginx/conf/nginx.conf:


这是新版本的问题,需要我们将log_format的定义放到server的前面。如果你是直接更改的nginx.conf文件,你会发现这一句原本就是在server的前面的。
