Lvs+Keepalived+Squid+Nginx+Mysql主从 高性能集群架构配置



Lvs+Keepalived+Squid+Nginx+Mysql主从 高性能集群架构配置_高性能集群架构


不足之处，请指出~~~~~~~~~

先进行优化：


vi /etc/sysctl.conf   # 编辑sysctl.conf文件添加以下内容
  1. net.ipv4.tcp_rmem = 4096 87380 4194304 
  2. net.ipv4.tcp_wmem = 4096 65536 4194304 
  3. net.core.wmem_default = 8388608 
  4. net.core.rmem_default = 8388608 
  5. net.core.rmem_max = 16777216 
  6. net.core.wmem_max = 16777216 
  7. net.core.netdev_max_backlog = 262144 
  8. net.core.somaxconn = 262144 
  9. net.ipv4.tcp_max_orphans = 3276800 
  10. net.ipv4.tcp_max_syn_backlog = 8192 
  11. net.ipv4.tcp_max_tw_buckets = 5000 
  12. net.ipv4.tcp_timestamps = 0 
  13. net.ipv4.tcp_synack_retries = 1 
  14. net.ipv4.tcp_syn_retries = 1 
  15. net.ipv4.tcp_tw_recycle = 1 
  16. net.ipv4.tcp_tw_reuse = 1 
  17. net.ipv4.tcp_mem = 786432 1048576 1572864 
  18. net.ipv4.tcp_fin_timeout = 30 
  19. net.ipv4.tcp_keepalive_time = 1200 
  20. net.ipv4.ip_local_port_range = 1024 65000
以上配置说明：

net.ipv4.tcp_rmem = 4096 87380 4194304：TCP读buffer,可参考的优化值: 32768 436600  873200

net.ipv4.tcp_wmem = 4096 65536 4194304：TCP写buffer,可参考的优化值: 8192 436600  873200

net.core.wmem_default：表示发送套接字缓冲区大小的缺省值（以字节为单位）

net.core.rmem_default：表示接收套接字缓冲区大小的缺省值（以字节为单位）
net.core.rmem_max ：表示接收套接字缓冲区大小的最大值（以字节为单位）
net.core.wmem_max：表示发送套接字缓冲区大小的最大值（以字节为单位）
net.core.netdev_max_backlog =  262144：每个网络接口接收数据包的速率比内核处理这些包的速率快时，允许送到队列的数据包的最大数目。
net.core.somaxconn =  262144：web应用中listen函数的backlog默认会给我们内核参数的net.core.somaxconn限制到128，而nginx定义的NGX_LISTEN_BACKLOG默认为511，所以有必要调整这个值。
net.ipv4.tcp_max_orphans = 3276800：系统中最多有多少个TCP套接字不被关联到任何一个用户文件句柄上。
net.ipv4.tcp_max_syn_backlog =  8192：表示SYN队列的长度，默认为1024，加大队列长度为8192，可以容纳更多等待连接的网络连接数。
net.ipv4.tcp_max_tw_buckets =  5000：表示系统同时保持TIME_WAIT套接字的最大数量，如果超过这个数字，TIME_WAIT套接字将立刻被清除并打印警告信息。减少它的最大数量，避免Squid服务器被大量的TIME_WAIT套接字拖死。
net.ipv4.tcp_timestamps =  0：时间戳可以避免序列号的卷绕。一个1Gbps的链路肯定会遇到以前用过的序列号，时间戳能够让内核接受这种“异常”的数据包，这里需要将其关掉。

net.ipv4.tcp_tw_recycle = 1：表示开启TCP连接中TIME-WAIT sockets的快速回收。

net.ipv4.tcp_tw_reuse = 1：表示开启重用，允许将TIME-WAIT sockets重新用于新的TCP连接。

net.ipv4.tcp_mem = 786432 1048576  1572864：同样有3个值,net.ipv4.tcp_mem[0]:低于此值，TCP没有内存压力；net.ipv4.tcp_mem[1]:在此值下，进入内存压力阶段；net.ipv4.tcp_mem[2]:高于此值，TCP拒绝分配socket。可根据物理内存大小进行调整，如果内存足够大的话，可适当往上调。建议94500000  915000000 927000000。
net.ipv4.tcp_fin_timeout =  30：表示如果套接字由本端要求关闭，这个参数决定了它保持在FIN-WAIT-2状态的时间。
net.ipv4.tcp_keepalive_time =  1200：表示当keepalive起用的时候，TCP发送keepalive消息的频度。缺省是2小时，改为20分钟。
net.ipv4.ip_local_port_range = 1024  65000：表示用于向外连接的端口范围。缺省情况下很小：32768到61000，改为1024到65000。
使配置立即生效：
/sbin/sysctl -p

mysql主从设置~~~~


  1. (1)首先确保主从服务器上的Mysql版本相同 
  2. (2)在主服务器上,设置一个从数据库的账户,使用REPLICATION SLAVE赋予权限,如: 
  3. mysql> GRANT REPLICATION SLAVE ON *.* TO 'slave001'@'10.10.10.59' IDENTIFIED BY 
  4. '123123'; 
  5. Query OK, 0 rows affected (0.13 sec) 
  6. (3)修改主数据库的配置文件my.cnf,开启BINLOG，并设置server-id的值，修改之后必须重启Mysql服务 
  7. [mysqld] 
  8. log-bin=mysql-bin
  9. binlog-ignore-db= mysql
  10. server-id=1
  11. (4)之后可以得到主服务器当前二进制日志名和偏移量，这个操作的目的是为了在从数据库启动后，从这个点开始进行数据的恢复 
  12. mysql> show master status\G; 
  13. *************************** 1. row *************************** 
  14. File: mysql-bin.000003 
  15. Position: 243 
  16. Binlog_Do_DB: 
  17. Binlog_Ignore_DB: 
  18. 1 row in set (0.00 sec) 
  19. (5)好了，现在可以停止主数据的的更新操作，并生成主数据库的备份，我们可以通过mysqldump到处数据到从数据库，当然了，你也可以直接用cp命令将数据文件复制到从数据库去 
  20. 注意在导出数据之前先对主数据库进行READ LOCK，以保证数据的一致性 
  21. mysql> flush tables with read lock; 
  22. Query OK, 0 rows affected (0.19 sec) 
  23. 之后是mysqldump 
  24. mysqldump -h127.0.0.1 -p3306 -uroot -p test > /home/chenyz/test.sql 
  25. 最好在主数据库备份完毕，恢复写操作 
  26. mysql> unlock tables; 
  27. Query OK, 0 rows affected (0.28 sec) 
  28. (6)将刚才主数据备份的test.sql复制到从数据库，进行导入 
  29. (7)接着修改从数据库的my.cnf,增加server-id参数,指定复制使用的用户,主数据库服务器的ip,端口以及开始执行复制日志的文件和位置 
  30. [mysqld] 
  31. server-id=2
  32. log-bin=mysql-bin
  33. master-host =10.10.10.58 
  34. master-user=test
  35. master-pass=123123
  36. master-port =3306
  37. master-connect-retry=60
  38. replicate-do-db =test
  39. (8)在从服务器上,启动slave进程 
  40. mysql> start slave; 
  41. (9)在从服务器进行show salve status验证 
  42. mysql> SHOW SLAVE STATUS\G 
  43. *************************** 1. row *************************** 
  44. Slave_IO_State: Waiting for master to send event 
  45. Master_Host: localhost 
  46. Master_User: root 
  47. Master_Port: 3306 
  48. Connect_Retry: 3 
  49. Master_Log_File: mysql-bin.003 
  50. Read_Master_Log_Pos: 79 
  51. Relay_Log_File: gbichot-relay-bin.003 
  52. Relay_Log_Pos: 548 
  53. Relay_Master_Log_File: mysql-bin .003 
  54. Slave_IO_Running: Yes 
  55. Slave_SQL_Running: Yes 
  56. (10)好了,现在可以在我们的主服务器做一些更新的操作,然后在从服务器查看是否已经更新
