安裝openresty

安裝openresty

#!/base/bin
APPDIR=/data/app
mkdir -p $APPDIR

# 設置APPDIR爲環境變量，因爲其它模塊安裝的時候需要用到這個變量
export APPDIR

UPROFILE=/etc/profile

yum install -y gcc-c++

# 切換到當前目錄
cd $WORKDIR

# 避免腳本目錄已經存在

# 設置PATH路徑

echo '#add nginx bin path' >> $UPROFILE 
echo "export PATH=$APPDIR/openresty/nginx/sbin:$PATH" >> $UPROFILE 
source $UPROFILE

echo Done

管理openresty  啓動nginx的腳本：

注意：這裏設置，該nginx啓動腳本和nginx配置在同一個目錄。

#!/bin/bash

workdir=$(dirname $(readlink -f $0))

conffile=$workdir/conf/nginx.conf

cmd=$1
echo "admin path:$workdir"
echo "your CMD:$cmd"

if [ "$cmd" == "start" ]; then
    nginx -p $workdir -c $conffile  
elif [ "$cmd" == "stop" ]; then
    nginx -p $workdir -c $conffile  -s stop 
elif [ "$cmd" == "quit" ]; then
    nginx -p $workdir -c $conffile  -s quit 
elif [ "$cmd" == "restart" ]; then
    nginx -p $workdir -c $conffile  -s stop 
    sleep 2
    nginx -p $workdir -c $conffile  
elif [ "$cmd" == "reload" ]; then
    nginx -p $workdir -c $conffile  -s reload 
elif [ "$cmd" == "test" ]; then
    nginx -p $workdir -c $conffile  -s test 
else
    echo "usage: ./admin.sh start|stop|quit|restart|reload|test"
fi

if [ $? -eq 0 ]; then
    echo ":::Done"
else
    echo ":::Failed"
fi

啓動nginx的時候，需要注意兩點：

（1）啓動選項 “-c” 可以指定配置文件，nginx可以根據不同的配置文件，開啓多個進程，但必須監聽不同的端口。

 （2）啓動選項 “-d”可以指定nginx的工作目錄，這個很重要。在openrest HttpLuaModule這個關鍵的模塊中，很多指令指定的路徑，就是以nginx的工作目錄爲相對路徑！

lua_package_path
syntax: lua_package_path <lua-style-path-str>
default: The content of LUA_PATH environ variable or Lua's compiled-in defaults.（默認爲LUA_PATH環境變量或者是Lua的編譯目錄）
context: http
Sets the Lua module search path used by scripts specified by set_by_lua, content_by_lua and others. The path string is in standard Lua path form, and ;; can be used to stand for the original search paths.
As from the v0.5.0rc29 release, the special notation $prefix or ${prefix} can be used in the search path string to indicate the path of the server prefix usuallydetermined by the -p PATH command-line option while starting the Nginx server.  (nginx開啓時指定的目錄)

類似的還有如下指令：
lua_package_cpath, init_by_lua_file, set_by_lua_file, content_by_lua_file,rewrite_by_lua_file等
