Atlas下載地址: https://github.com/Qihoo360/Atlas/releases
Atlas是出於360的, 比mysql-proxy更穩定, 部署起來更方便。
環境:
proxy:192.168.99.60
master:192.168.99.61
slave:192.168.99.62
1.安裝
由於我使用的是rpm包, 直接安裝
rpm -ivh Atlas-2.2.el6.x86_64.rpm
就是這么簡單, 安裝完成。
目錄默認在:
/usr/local/mysql-proxy
一覽目錄結構:
total 16 drwxr-xr-x. 2 root root 4096 Dec 12 10:04 bin drwxr-xr-x. 2 root root 4096 Dec 12 11:04 conf drwxr-xr-x. 3 root root 4096 Dec 12 10:04 lib drwxr-xr-x. 2 root root 4096 Dec 12 11:17 log
2.配置文件
cd /usr/local/mysql-proxy/conf vim test.cnf
很多中文指示, 完美
[mysql-proxy] #帶#號的為非必需的配置項目 #管理接口的用戶名 admin-username = admin #管理接口的密碼 admin-password = admin #Atlas后端連接的MySQL主庫的IP和端口,可設置多項,用逗號分隔 proxy-backend-addresses = 192.168.99.61:3306 #Atlas后端連接的MySQL從庫的IP和端口,@后面的數字代表權重,用來作負載均衡,若省略則默認為1,可設置多項,用逗號分隔 proxy-read-only-backend-addresses = 192.168.99.62:3306@1 #用戶名與其對應的加密過的MySQL密碼,密碼使用PREFIX/bin目錄下的加密程序encrypt加密,下行的user1和user2為示例,將其替換為你的MySQL的用戶名和加密密碼! pwds = admin:la1Ux+Bu4zo= #設置Atlas的運行方式,設為true時為守護進程方式,設為false時為前台方式,一般開發調試時設為false,線上運行時設為true,true后面不能有空格。 daemon = true #設置Atlas的運行方式,設為true時Atlas會啟動兩個進程,一個為monitor,一個為worker,monitor在worker意外退出后會自動將其重啟,設為false時只有worker,沒有monitor,一般開發調試時設為false,線上運行時設為true,true后面不能有空格。 keepalive = true #工作線程數,對Atlas的性能有很大影響,可根據情況適當設置 event-threads = 8 #日志級別,分為message、warning、critical、error、debug五個級別 log-level = message #日志存放的路徑 log-path = /usr/local/mysql-proxy/log #SQL日志的開關,可設置為OFF、ON、REALTIME,OFF代表不記錄SQL日志,ON代表記錄SQL日志,REALTIME代表記錄SQL日志且實時寫入磁盤,默認為OFF sql-log = REALTIME #慢日志輸出設置。當設置了該參數時,則日志只輸出執行時間超過sql-log-slow(單位:ms)的日志記錄。不設置該參數則輸出全部日志。 #sql-log-slow = 10 #實例名稱,用於同一台機器上多個Atlas實例間的區分 instance = test #Atlas監聽的工作接口IP和端口 proxy-address = 0.0.0.0:1234 #Atlas監聽的管理接口IP和端口 admin-address = 0.0.0.0:2345 #分表設置,此例中person為庫名,mt為表名,id為分表字段,3為子表數量,可設置多項,以逗號分隔,若不分表則不需要設置該項 #tables = person.mt.id.3 #默認字符集,設置該項后客戶端不再需要執行SET NAMES語句 #charset = utf8 #允許連接Atlas的客戶端的IP,可以是精確IP,也可以是IP段,以逗號分隔,若不設置該項則允許所有IP連接,否則只允許列表中的IP連接 #client-ips = 127.0.0.1, 192.168.1 #Atlas前面掛接的LVS的物理網卡的IP(注意不是虛IP),若有LVS且設置了client-ips則此項必須設置,否則可以不設置 #lvs-ips = 192.168.1.1
3.啟動
cd /usr/local/mysql-proxy/bin ./mysql-proxyd test start
在這個目錄下有mysql-proxy mysql-proxyd, 第一個是mysql團隊的, 第二個是屬於360團隊的, 我們使用的是360的。
端口
netstat -tlnp | grep mysql-proxy tcp 0 0 0.0.0.0:1234 0.0.0.0:* LISTEN 7270/mysql-proxy tcp 0 0 0.0.0.0:2345 0.0.0.0:* LISTEN 7270/mysql-proxy
留意您的配置文件: 1234端口是api接口, 提供能外部進行工作連接的, 2345是屬於內部管理的, 比如查詢負載主機狀態等。
進程
ps aux | grep mysql-proxy root 1227 0.0 0.0 103244 856 pts/5 S+ 16:03 0:00 grep mysql-proxy root 7269 0.0 0.0 64916 5168 ?

查詢日志
/usr/local/mysql-proxy/log ls sql_test.log test.log test.pid
sql_test.log是運行過的sql記錄, test.log是日志,test.pid是進程ID
