线上服务器后端G1组机器下线，同时上线G22服务器 16/06/25 16:30已完成[编辑]

1.编辑两台反向代理服务器的/etc/nginx/nginx.conf文件，注释掉upstream模块的G1组5台服务器 

http {
    upstream www.52jiaoshi.com {
        #G1
		#server 123.56.154.254:8089;
        #server 123.57.57.241:8089;
        #server 123.56.77.165:8089;
        #server 123.56.238.65:8089;
        #server 123.56.47.69:8089;
        #server 123.57.143.153:8089;
		#G2
        #server 123.57.180.46:8089;
        server 123.57.26.145:8089;
        server 123.57.27.27:8089;
        server 123.56.253.188:8089;
        server 101.200.135.96:8089;
        server 123.56.75.106:8089;
        ip_hash;
    }

2.分别重启两台反向代理服务器的nginx服务 

nginx -s reload

52jiaoshi线上代码发布脚本增加回滚机制 16/06/25 15:00已完成[编辑]

1.在发布脚本中添加，将每次发布的最新commit版本号写入发布日志
	git branch master
	git checkout master
	git pull origin master
	git log --pretty=format:'[%h] at [%cd] by [%ce] : [%s]' -n 1|xargs echo -e "`date`\n" >> /alidata/pub/jiaoshi/publish_master/publish.log

	Fri Jun 24 16:15:04 CST 2016
	 [73764e9] at [Mon Jun 20 14:46:45 2016 +0800] by [qiaochenglei@52jiaoshi.com] : [ShellCommit 160620-144643]
 
2.在回滚脚本中新建rollback分支，并选择想要重新发布的版本号（此版本号为7位简短版，git可以自动搜索）
	git checkout -b rollback 73764e9

3.成功发布并测试正常后，删除rollback分支
	git branch -d rollback
	
4.查看已经发布过的代码版本历史
	ido pub log

52jiaoshi.com增加https接口 16/06/23 22:00已完成[编辑]

1.上传api.52jiaohsi.com的证书和私钥到两台nginx反向代理服务器的/etc/nginx/ssl目录下
	api.52jiaoshi.com_bundle.crt  
	api.52jiaoshi.com.key
2.修改nginx配置文件，增加虚拟主机并添加ssl模块配置信息
	vim /etc/nginx/nginx.conf
	
	http模块增加（nginx主可以不用添加）：
	upstream alpha.52jiaoshi.com {
        ip_hash;
        server 10.172.220.56:8089;      #G22_alpha
        server 10.172.225.201:8089;     #zabbix_alpha
    }

    底部追加：
	server {
        listen  443;
        server_name     api.52jiaoshi.com;
        ssl on;
        ssl_certificate /etc/nginx/ssl/wosign/api.52jiaoshi.com_bundle.crt;
        ssl_certificate_key /etc/nginx/ssl/wosign/api.52jiaoshi.com.key;

        location / {
                root    html;
                index   index.html index.htm;

        #access_log  logs/test.access.log  main;

        #proxy_set_header Host $host;
        #proxy_set_header X-Real-IP $remote_addr;
        #proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_pass http://www.52jiaoshi.com;
        }
    }

    server {
        listen 80;
        server_name api.52jiaoshi.com;
        rewrite ^(.*) https://$server_name$1 permanent;
    }

    server {
        listen  80;
        server_name     www.52jiaoshi.com;

	    location / {
                root    html;
                index   index.html index.htm;

        #access_log  logs/test.access.log  main;

        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_connect_timeout   600;
        proxy_send_timeout      600;
        proxy_read_timeout      600;
        proxy_pass http://www.52jiaoshi.com;
        }

        error_page  404         /404.html;
        location = /404.html {
                root   /usr/share/nginx/html;
        }

        #redirect server error pages to the static page /50x.html

        error_page  500 502 503 504  /50x.html;
        location = /50x.html {
                root   /usr/share/nginx/html;
        }
    }

    server {
        listen  80;
        server_name      52jiaoshi.com;
        return 301 $scheme://www.52jiaoshi.com$request_uri;
    }

    server {                                           #nginx主可以不用添加
        listen  443;
        server_name     alpha.52jiaoshi.com;
        ssl on;
        ssl_certificate /etc/nginx/ssl/wosign/alpha.52jiaoshi.com_bundle.crt;
        ssl_certificate_key /etc/nginx/ssl/wosign/alpha.52jiaoshi.com.key;

        location / {
                root    html;
                index   index.html index.htm;

        #access_log  logs/test.access.log  main;

        #proxy_set_header Host $host;
        #proxy_set_header X-Real-IP $remote_addr;
        #proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_pass http://alpha.52jiaoshi.com;
        }
    }
3.重新载入nginx配置
	nginx -s reload

52gongji添加硬盘 16/06/07 0:30已完成[编辑]

1.关闭httpd服务
	/alidata/server/httpd/bin/httpd -k stop
2.关闭php推送服务
	killall php
3.关闭redis服务
	redis-cli -a Born shutdown
4./alidata目录改名为/alidata-backup
	mv /alidata /alidata-backup
5.建立新的/alidata目录作为新磁盘挂载点
	mkdir /alidata
6.挂载新磁盘到/alidata目录下
	mount /dev/xvdb /alidata
7.将原目录数据拷贝到新的目录里
	cp -a /alidata-backup/* /alidata/
8.启动httpd服务
	/alidata/server/httpd/bin/httpd -k start
9.启动php推送脚本
	cd  /alidata/server/httpd/htdocs/gongji/pushServer/ApnsPHP-master/
	nohup php apnsServer.php &
	cd /alidata/server/httpd/htdocs/gongji/pushServer/umeng/
	nohup php umengServer.php &
10.启动redis服务
	redis-server /etc/redis.conf

REDIS加从 16/06/02 0:30 已完成 步骤参见WORD[编辑]

1、停止线上redis主服务器的持久化功能
	redis>config set save ""
	redis>config set appendonly 
1.	停止线上redis主服务器的持久化功能
	 redis>config set save “”							 #关闭快照持久化
	 redis>config set appendonly no				  #关闭AOF持久化
2.	手动执行快照备份，备份线上redis数据
	redis>bgsave
	cp dump.rdb /bak/dump.rdb.bak		        #快照文件同样复制一份，以防原文件有问题
3.	在redis从的配置文件中加入下面一行，启动redis从服务器，自动执行主从同步
	slaveof 10.170.237.175 6379
4.	如果主库发生错误，重启redis服务即可（自动进行数据恢复）
	redis-cli 
	redis>auth Born
	redis>shutdown
	redis-server /etc/redis.conf
5.	同步成功后，redis从开启持久化功能，redis主关闭持久化功能，减少主I/O压力
从（开启AOF持久化）：
	redis-cli -a Born config set appendonly yes
主（用计划任务完成快照持久化备份，每小时备份一次）：
	crontab –e
	0 * * * * /usr/bin/redis-cli -a Born bgsave
