方案一，在tomcat的workers.PRoperties里面配置相關條件

worker.tomcat.lbfactor=50worker.tomcat.cachesize=10worker.tomcat.cache_timeout=600worker.tomcat.socket_keepalive=1worker.tomcat.socket_timeout=300

linux內核優化：

vi /etc/sysctl.conf # 編輯sysctl.conf文件添加以下內容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 873200

net.ipv4.tcp_wmem = 4096 65536 4194304：TCP寫buffer,可參考的優化值: 8192 436600 873200

net.core.wmem_default：表示發送套接字緩沖區大小的缺省值（以字節為單位）

net.core.rmem_default：表示接收套接字緩沖區大小的缺省值（以字節為單位）net.core.rmem_max ：表示接收套接字緩沖區大小的最大值（以字節為單位）net.core.wmem_max：表示發送套接字緩沖區大小的最大值（以字節為單位）net.core.netdev_max_backlog = 262144：每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，允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默認會給我們內核參數的net.core.somaxconn限制到128，而nginx定義的NGX_LISTEN_BACKLOG默認為511，所以有必要調整這個值。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，默認為1024，加大隊列長度為8192，可以容納更多等待連接的網絡連接數。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，如果超過這個數字，TIME_WAIT套接字將立刻被清除并打印警告信息。減少它的最大數量，避免Squid服務器被大量的TIME_WAIT套接字拖死。net.ipv4.tcp_timestamps = 0：時間戳可以避免序列號的卷繞。一個1Gbps的鏈路肯定會遇到以前用過的序列號，時間戳能夠讓內核接受這種“異常”的數據包，這里需要將其關掉。net.ipv4.tcp_tw_recycle = 1：表示開啟TCP連接中TIME-WAIT sockets的快速回收。

net.ipv4.tcp_tw_reuse = 1：表示開啟重用，允許將TIME-WAIT sockets重新用于新的TCP連接。

net.ipv4.tcp_mem = 786432 1048576 1572864：同樣有3個值,net.ipv4.tcp_mem[0]:低于此值，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]:高于此值，TCP拒絕分配socket?？筛鶕锢韮却娲笮∵M行調整，如果內存足夠大的話，可適當往上調。建議94500000 915000000 927000000。net.ipv4.tcp_fin_timeout = 30：表示如果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，改為20分鐘。net.ipv4.ip_local_port_range = 1024 65000：表示用于向外連接的端口范圍。缺省情況下很?。?2768到61000，改為1024到65000。

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賬戶,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,開啟BINLOG，并設置server-id的值，修改之后必須重啟Mysql服務  [mysqld] log-bin=mysql-binbinlog-ignore-db= mysqlserver-id=1  (4)之后可以得到主服務器當前二進制日志名和偏移量，這個操作的目的是為了在從數據庫啟動后，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，現在可以停止主數據的的更新操作，并生成主數據庫的備份，我們可以通過mysqldump到處數據到從數據庫，當然了，你也可以直接用cp命令將數據文件復制到從數據庫去 注意在導出數據之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)  之后是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，恢復寫操作  mysql> unlock tables; Query OK, 0 rows affected (0.28 sec)  (6)將剛才主數據備份的test.sql復制到從數據庫，進行導入 (7)接著修改從數據庫的my.cnf,增加server-id參數,指定復制使用的用戶,主數據庫服務器的ip,端口以及開始執行復制日志的文件和位置  [mysqld] server-id=2 log-bin=mysql-binmaster-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,啟動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
