1.安裝依賴環境
yum -y install gcc zlib zlib-devel pcre-devel openssl openssl-devel
2.安裝LuaJIT
cd /usr/local/ mkdir LuaJIT cd /usr/local/LuaJIT
wget http://luajit.org/download/LuaJIT-2.0.2.tar.gz
tar –xvf LuaJIT-2.0.2.tar.gz cd LuaJIT-2.0.2 make install
3.安裝nginx
cd /usr/local/ mkdir nginx
下載ngx_devel_kit
wget https://github.com/simpl/ngx_devel_kit/archive/v0.3.0.tar.gz
下載lua-nginx-module
wget https://github.com/openresty/lua-nginx-module/archive/v0.10.9rc7.tar.gz
下載nginx
wget http://nginx.org/download/nginx-1.12.1.tar.gz
解壓文件
tar -xvf ngx_devel_kit-0.3.0 .tar.gz tar -xvf lua-nginx-module-0.10.9rc7.tar.gz tar -xvf nginx-1.12.1.tar.gz
編譯nginx
cd nginx-1.12.1 ./configure --prefix=/usr/local/nginx --add-module=../ngx_devel_kit-0.3.0 --add-module=../lua-nginx-module-0.10.9rc7
安裝
make
make install
或者合並兩個命令（4表示並行運行任務的數量）
make -j 4 && make install
啟動nginx
cd /usr/local/nginx/sbin ./nginx
測試是否啟動成功:
訪問 http：127.0.0.1:80
顯示welcome to n ginx！表示啟動成功
關閉nginx
./nginx –s stop
4.安裝redis
cd /usr/local mkdir redis
下載
wget http://download.redis.io/releases/ redis-2.8.17.tar.gz
解壓
tar -xvf redis-2.8.17.tar.gz
進入解壓后的文件夾
cd redis-2.8.17
安裝
make
啟動redis(&表示后台運行)
cd src
./redis-server &
啟動成功后按ctrl+c退出啟動界面
測試
./redis-cli set foo liq ---OK get foo ---liq
關閉redis
SHUTDOWN
5.配置redis主從
5.1主reids 配置文件
復制一份redis的配置文件：
cd /usr/local/redis/redis-2.8.17 mkdir –p 6379/data 6380/data cp redis.conf /usr/local/redis/redis-2.8.17/6379/data/redis-6379.conf
編輯文件
cd /usr/local/redis/ redis-2.8.17/6379/data/ vim redis-6379.conf
cd /usr/local/redis/ redis-2.8.17/6379/data/ vim redis-6379.conf
5.1.1
daemonize no
修改為：
daemonize yes (后台程序方式運行)
5.1.2
pidfile /var/run/redis_6379.pid
修改為：
pidfile /usr/local/redis/redis-2.8.17/6379/redis_6379.pid
5.1.3
//設置請求密碼
requirepass system
5.1.4
//設置數據文件路徑
dir /usr/local/redis/redis-2.8.17/6379/data
5.2從reids 配置文件
cp /usr/local/redis/redis-2.8.17/6379/data/redis-6379.conf /usr/local/redis/redis-2.8.17/6380/data/redis-6380.conf
5.2.1
port 改為6380
5.2.2
pidfile 改為/usr/local/redis/redis-2.8.17/6380/redis_6380.pid
5.2.2
刪除 requirepass system
5.2.3
//設置數據文件路徑
dir /usr/local/redis/redis-2.8.17/6380/data
5.2.4
添加從屬關系
slaveof 127.0.0.1 6379
5.2.5
添加主redis訪問密碼
masterauth system
5.3啟動redis
/usr/local/redis/redis-2.8.17/src/redis-server /usr/local/redis/redis-2.8.17/6379/redis-6379.conf
/usr/local/redis/redis-2.8.17/src/redis-server /usr/local/redis/redis-2.8.17/6380/redis-6380.conf
5.4測試主從
在主redis中存數據
cd /usr/local/redis/redis-2.8.17/src ./redis-cli -h 127.0.0.1 -p 6379 auth system set foo test
ctrl+c退出
在從redis中取數據
./redis-cli -h 127.0.0.1 -p 6380 get foo
6.安裝lua-resty-redis
從https://github.com/openresty/lua-resty-redis.git下載lua-resty-redis-master后解壓
將lib包安裝到lua庫
cd lua-resty-redis-master
make && make install
安裝完成之后在/usr/local/lib/lua/resty里面會有redis.lua
7.修改nginx配置文件
cd /usr/local/nginx/conf vim nginx.conf
7.1
http內添加 lua_package_path "/usr/local/lib/lua/?.lua;;";
7.2
server listen改為 9080;
7.3
server 內添加
location /lua/set {
default_type 'text/plain';
content_by_lua_file conf/lua/setKeyValue.lua;
}
location /lua/get {
default_type 'text/plain';
content_by_lua_file conf/lua/getKey.lua;
}
完整配置文件nginx.cnof：
worker_processes 1; events { worker_connections 1024; } http { include mime.types; default_type application/octet-stream; lua_package_path "/usr/local/lib/lua/?.lua;;"; sendfile on; keepalive_timeout 65; server { listen 9080; server_name localhost; location / { root html; index index.html index.htm; } location /lua/set { default_type 'text/plain'; content_by_lua_file conf/lua/setKeyValue.lua; } location /lua/get { default_type 'text/plain'; content_by_lua_file conf/lua/getKey.lua; } error_page 500 502 503 504 /50x.html; location = /50x.html { root html; } } }
8.編寫content_by_lua_file對應的lua腳本
8.1
#對應nginx中的配置： content_by_lua_file conf/lua/setKeyValue.lua;
cd /usr/local/nginx/conf mkdir lua cd lua vim setKeyValue.lua
setKeyValue.lua代碼：--receive request params local request_method = ngx.var.request_method local args = nil local key = nil local value = nil --獲取參數的值 if "GET" == request_method then args = ngx.req.get_uri_args() elseif "POST" == request_method then ngx.req.read_body() args = ngx.req.get_post_args() end key = args["key"] value = args["value"] --connect redis local redis = require "resty.redis" local cache = redis.new() local ok, err = cache.connect(cache, '127.0.0.1', '6379') cache:set_timeout(60000) if not ok then ngx.say("failed to connect:", err) return end -- 請注意這里 auth 的調用過程 -- check password local count count, err = cache:get_reused_times() if 0 == count then ok, err = cache:auth("system") if not ok then ngx.say("failed to auth: ", err) return end elseif err then ngx.say("failed to get reused times: ", err) return end local res, err = cache:set(key, value) if not res then ngx.say("failed to set "..key..": ", err) return end if res == ngx.null then ngx.say(key.." not found.") return end ngx.say("set redis value >>> "..key..": ", res) local ok, err = cache:close() if not ok then ngx.say("failed to close:", err) return end
8.2
#對應nginx中的配置： content_by_lua_file conf/lua/getKey.lua;
vim getKey.lua
getKey.lua代碼：
--receive request params local request_method = ngx.var.request_method local args = nil local key = nil local value = nil --獲取參數的值 if "GET" == request_method then args = ngx.req.get_uri_args() elseif "POST" == request_method then ngx.req.read_body() args = ngx.req.get_post_args() end key = args["key"] value = args["value"] --connect redis local redis = require "resty.redis" local cache = redis.new() local ok, err = cache.connect(cache, '127.0.0.1', '6380') cache:set_timeout(60000) if not ok then ngx.say("failed to connect:", err) return end local res, err = cache:get(key) if not res then ngx.say("failed to get "..key..": ", err) return end if res == ngx.null then ngx.say(key.." not found.") return end ngx.say("get from redis >>> "..key..": ", res) local ok, err = cache:close() if not ok then ngx.say("failed to close:", err) return end
9.開啟端口映射（如果不是安裝在虛擬機上的不需要此步驟）
9.1開啟虛擬機端口映射：
9.2開放9080端口的防火牆（--permanent永久生效，沒有此參數重啟后失效）:
firewall-cmd --zone=public --add-port=9080/tcp --permanent
10.重新啟動nginx
cd /usr/local/nginx/sbin ./nginx
11.查看效果
存值 -- 訪問網址並傳參：
http://localhost:9080/lua/set?key=foo&value=test1
取值 -- 訪問網址並傳參：
http://localhost:9080/lua/get?key=foo
