初步设计
- mysql开放远端连接（应用可以水平部署，数据库目前还不能水平部署）
- 服务端水平对称部署
- 验证访问

5 years ago 先开放数据库远程连接
grant all privileges on *.* to root@'%' identified by 'root'; # 所有权限给知道root密码的人
flush privileges;安装java环境直接采用
chmod -R 777 XXX.rpm
rpm -ivh XXX.rpm新建gethost.js
var g_host = "localhost:8090";引入对应的js文件
<script src="./gethost.js" type="text/javascript"></script>替换原本localhost的地方
url: "http://"+g_host+"/item/create",chmod -R 777 openresty-1.13.6.2.tar.gz
tar -zxvf openresty-1.13.6.2.tar.gz./configure # 进行编译会报错，产生错误
./configure: error: the HTTP rewrite module requires the PCRE library.应该按照官网指示安装新的依赖关系：官网

具体命令
将本地的static文件下内容都上传到//usr/local/openresty/nginx/html文件夹下
scp -r * root@47.103.27.246://usr/local/openresty/nginx/html首先修改规则实现动静分离，将所有文件copy到resources下面
server {
listen 80;
server_name localhost;
#charset koi8-r;
#access_log logs/host.access.log main;
location /resources/ # 注意两边都有斜杠，是指命中之后进行操作{
alias /usr/local/openresty/nginx/html/resources/; # alias是替换的意思，这个斜杠也很重要！！
index index.html index.htm;
}root@iZuf6ivhkgilwhtmycw9niZ://usr/local/openresty/nginx# ps -ef | grep nginx
root 17352 1 0 10:55 ? 00:00:00 nginx: master process sbin/nginx -c conf/nginx.conf

nobody 17661 17352 0 11:31 ? 00:00:00 nginx: worker process
root 17663 4492 0 11:31 pts/1 00:00:00 grep --color=auto nginx 对应的master进程没有变，但是对应的worker进程却发生了变化。

5 years ago 设置upstrem server
upstream backend_server {
server 172.19.228.205:8090 weight=1; # 注意用私有地址快一点
server ···
}设置动态请求location为proxy pass路径
···
location / { # 其余都算作动态处理
proxy_pass http://backend_server;
proxy_set_header Host $http_host:$proxy_port;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}开启tomcat access log验证，只会损失一部分性能，但是用处很大，可以定位问题，并且观察消耗
# tomcat日志
server.tomcat.accesslog.enabled=true
server.tomcat.accesslog.directory=/var/www/java/seckillmall/tomcat
# 日志格式 h=ip地址，u=user，t=处理时长，r=请求第一行，s=状态码
server.tomcat.accesslog.pattern=%h %l %u %t "%r" %s %b %Depoll多路复用，指的是socket
master worker进程模型
协程机制（非阻塞模型）
