Linux内核优化：
vi /etc/sysctl.conf # 编辑sysctl.conf文件添加以下内容
net.ipv4.tcp_rmem =
net.ipv4.tcp_wmem =
net.core.wmem_default =
net.core.rmem_default =
net.core.rmem_max =
net.core.wmem_max =
net.core.netdev_max_backlog =
net.core.somaxconn =
net.ipv4.tcp_max_orphans =
net.ipv4.tcp_max_syn_backlog =
net.ipv4.tcp_max_tw_buckets =
net.ipv4.tcp_timestamps =
net.ipv4.tcp_synack_retries =
net.ipv4.tcp_syn_retries =
net.ipv4.tcp_tw_recycle =
net.ipv4.tcp_tw_reuse =
net.ipv4.tcp_mem =
net.ipv4.tcp_fin_timeout =
net.ipv4.tcp_keepalive_time =
net.ipv4.ip_local_port_range =
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。

mysql主从设置：
()首先确保主从服务器上的Mysql版本相同
()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: mysql> GRANT REPLICATION SLAVE ON *.* TO 'slave001'@'10.10.10.59' IDENTIFIED BY
'';
Query OK, rows affected (0.13 sec) ()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 [mysqld]
log-bin=mysql-bin
binlog-ignore-db= mysql
server-id= ()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 mysql> show master status\G;
*************************** . row ***************************
File: mysql-bin.

Binlog_Ignore_DB:
row in set (0.00 sec) ()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
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 mysql> flush tables with read lock;
Query OK, rows affected (0.19 sec) 之后是mysqldump mysqldump -h127.0.0. -p3306 -uroot -p test > /home/chenyz/test.sql 最好在主数据库备份完毕，恢复写操作 mysql> unlock tables;
Query OK, rows affected (0.28 sec) ()将刚才主数据备份的test.sql复制到从数据库，进行导入
()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 [mysqld]
