LVS+Keepalived+Squid+Nginx+MySQL主從高性能集羣架構部署方案
方案一，在tomcat的workers.properties裏面配置相關條件php
worker.tomcat.lbfactor=50 worker.tomcat.cachesize=10 worker.tomcat.cache_timeout=600 worker.tomcat.socket_keepalive=1 worker.tomcat.socket_timeout=300
Linux內核優化：css
vi /etc/sysctl.conf # 編輯sysctl.conf文件添加如下內容
net.ipv4.tcp_rmem = 4096 87380 4194304 net.ipv4.tcp_wmem = 4096 65536 4194304 net.core.wmem_default = 8388608 net.core.rmem_default = 8388608 net.core.rmem_max = 16777216 net.core.wmem_max = 16777216 net.core.netdev_max_backlog = 262144 net.core.somaxconn = 262144 net.ipv4.tcp_max_orphans = 3276800 net.ipv4.tcp_max_syn_backlog = 8192 net.ipv4.tcp_max_tw_buckets = 5000 net.ipv4.tcp_timestamps = 0 net.ipv4.tcp_synack_retries = 1 net.ipv4.tcp_syn_retries = 1 net.ipv4.tcp_tw_recycle = 1 net.ipv4.tcp_tw_reuse = 1 net.ipv4.tcp_mem = 786432 1048576 1572864 net.ipv4.tcp_fin_timeout = 30 net.ipv4.tcp_keepalive_time = 1200 net.ipv4.ip_local_port_range = 1024 65000
以上配置說明：
net.ipv4.tcp_rmem = 4096 87380 4194304：TCP讀buffer,可參考的優化值: 32768 436600 873200html
net.ipv4.tcp_wmem = 4096 65536 4194304：TCP寫buffer,可參考的優化值: 8192 436600 873200mysql
net.core.wmem_default：表示發送套接字緩衝區大小的缺省值（以字節爲單位）linux
net.core.rmem_default：表示接收套接字緩衝區大小的缺省值（以字節爲單位）
net.core.rmem_max ：表示接收套接字緩衝區大小的最大值（以字節爲單位）
net.core.wmem_max：表示發送套接字緩衝區大小的最大值（以字節爲單位）
net.core.netdev_max_backlog = 262144：每一個網絡接口接收數據包的速率比內核處理這些包的速率快時，容許送到隊列的數據包的最大數目。
net.core.somaxconn = 262144：web應用中listen函數的backlog默認會給咱們內核參數的net.core.somaxconn限制到128，而nginx定義的NGX_LISTEN_BACKLOG默認爲511，因此有必要調整這個值。
net.ipv4.tcp_max_orphans = 3276800：系統中最多有多少個TCP套接字不被關聯到任何一個用戶文件句柄上。
net.ipv4.tcp_max_syn_backlog = 8192：表示SYN隊列的長度，默認爲1024，加大隊列長度爲8192，能夠容納更多等待鏈接的網絡鏈接數。
net.ipv4.tcp_max_tw_buckets = 5000：表示系統同時保持TIME_WAIT套接字的最大數量，若是超過這個數字，TIME_WAIT套接字將馬上被清除並打印警告信息。減小它的最大數量，避免Squid服務器被大量的TIME_WAIT套接字拖死。
net.ipv4.tcp_timestamps = 0：時間戳能夠避免序列號的卷繞。一個1Gbps的鏈路確定會遇到之前用過的序列號，時間戳可以讓內核接受這種「異常」的數據包，這裏須要將其關掉。
net.ipv4.tcp_tw_recycle = 1：表示開啓TCP鏈接中TIME-WAIT sockets的快速回收。nginx
net.ipv4.tcp_tw_reuse = 1：表示開啓重用，容許將TIME-WAIT sockets從新用於新的TCP鏈接。web
net.ipv4.tcp_mem = 786432 1048576 1572864：一樣有3個值,net.ipv4.tcp_mem[0]:低於此值，TCP沒有內存壓力；net.ipv4.tcp_mem[1]:在此值下，進入內存壓力階段；net.ipv4.tcp_mem[2]:高於此值，TCP拒絕分配socket。可根據物理內存大小進行調整，若是內存足夠大的話，可適當往上調。建議94500000 915000000 927000000。
net.ipv4.tcp_fin_timeout = 30：表示若是套接字由本端要求關閉，這個參數決定了它保持在FIN-WAIT-2狀態的時間。
net.ipv4.tcp_keepalive_time = 1200：表示當keepalive起用的時候，TCP發送keepalive消息的頻度。缺省是2小時，改成20分鐘。
net.ipv4.ip_local_port_range = 1024 65000：表示用於向外鏈接的端口範圍。缺省狀況下很小：32768到61000，改成1024到65000。sql

mysql主從設置：
(1)首先確保主從服務器上的Mysql版本相同 (2)在主服務器上,設置一個從數據庫的帳戶,使用REPLICATION SLAVE賦予權限,如: mysql> GRANT REPLICATION SLAVE ON *.* TO 'slave001'@'10.10.10.59' IDENTIFIED BY '123123'; Query OK, 0 rows affected (0.13 sec) (3)修改主數據庫的配置文件my.cnf,開啓BINLOG，並設置server-id的值，修改以後必須重啓Mysql服務 [mysqld] log-bin=mysql-bin binlog-ignore-db= mysql server-id=1 (4)以後能夠獲得主服務器當前二進制日誌名和偏移量，這個操做的目的是爲了在從數據庫啓動後，從這個點開始進行數據的恢復 mysql> show master status\G; *************************** 1. row *************************** File: mysql-bin.000003 Position: 243 Binlog_Do_DB: Binlog_Ignore_DB: 1 row in set (0.00 sec) (5)好了，如今能夠中止主數據的的更新操做，並生成主數據庫的備份，咱們能夠經過mysqldump處處數據到從數據庫，固然了，你也能夠直接用cp命令將數據文件複製到從數據庫去 注意在導出數據以前先對主數據庫進行READ LOCK，以保證數據的一致性 mysql> flush tables with read lock; Query OK, 0 rows affected (0.19 sec) 以後是mysqldump mysqldump -h127.0.0.1 -p3306 -uroot -p test > /home/chenyz/test.sql 最好在主數據庫備份完畢，恢復寫操做 mysql> unlock tables; Query OK, 0 rows affected (0.28 sec) (6)將剛纔主數據備份的test.sql複製到從數據庫，進行導入 (7)接着修改從數據庫的my.cnf,增長server-id參數,指定複製使用的用戶,主數據庫服務器的ip,端口以及開始執行復制日誌的文件和位置 [mysqld] server-id=2 log-bin=mysql-bin master-host =10.10.10.58 master-user=test master-pass=123123 master-port =3306 master-connect-retry=60 replicate-do-db =test (8)在從服務器上,啓動slave進程 mysql> start slave; (9)在從服務器進行show salve status驗證 mysql> SHOW SLAVE STATUS\G *************************** 1. row *************************** Slave_IO_State: Waiting for master to send event Master_Host: localhost Master_User: root Master_Port: 3306 Connect_Retry: 3 Master_Log_File: mysql-bin.003 Read_Master_Log_Pos: 79 Relay_Log_File: gbichot-relay-bin.003 Relay_Log_Pos: 548 Relay_Master_Log_File: mysql-bin .003 Slave_IO_Running: Yes Slave_SQL_Running: Yes
