LVS+Keepalived+Squid+Nginx+MySQL主从高性能集群架构部署方案


方案一，在tomcat的workers.properties里面配置相关条件

worker.tomcat.lbfactor=====

 

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 =   =   = = = = = = = = = = = = = = =   = = =

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.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_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。

/sbin/sysctl -p

 LVS + keepalived 配置：

master的配置： 
mkdir /usr/local/src//usr/local/src/
wget http:
|--s /usr/src/kernels/$(uname -r)/usr/src/-s /usr/src/kernels/.* /usr/src/--&&-.-./configure&& make &&/usr/local/etc/rc.d/init.d/keepalived /etc/rc.d/init.d//usr/local/etc/sysconfig/keepalived /etc/sysconfig//etc//usr/local/etc/keepalived/keepalived.conf /etc/keepalived//usr/local/sbin/keepalived /usr/sbin/|>> /usr/local/etc/keepalived/keepalived.conf <<! Configuration File .    #  另一端 .. . . .

backup主机的配置：

mkdir /usr/local/src//usr/local/src/
wget http:

Squid缓存反向代理配置：

#!/bin/
tar jxvf squid-/configure --prefix=/usr/local/--enable--io=--enable-storeio=--enable-useragent---enable-referer---enable-kill-parent---enable-forward---enable---enable-cache---enable--err-language=--enable---enable-removal-policies=--enable-large-cache---disable----enable-x-accelerator---enable-follow-x-forwarded---disable-ident---with-large---with-filedescriptors=>> /usr/local/squid/etc/squid.conf <<.:/tmp1   ^ftp:               %     ^gopher:            %             %     %>a %ui %un [%tl]  %Hs %<st   %Ss:%//log/squid///log/squid///log/squid/./.-----i ^-i .+. parent   no-query originserver name=web1 round-. parent   no-query originserver name=web2 round-.com *..^ftp:  % ^gopher:  % ^gopher:  %  % -i \.css$            %     -i \.js$            %     -i \.html$           %     -i \.jpg$           %     -i \.gif$           %     -i \.swf$           %     -i \.jpg$           %     -i \.png$           %     -i \.bmp$           %     -i \.doc$           %     -i \.ppt$           %     -i \.xls$           %     -i \.pdf$           %     -i \.rar$           %     -i \.zip$           %     -i \.txt$           %     ///log/-R nobody:nobody / /-R nobody:nobody //log//usr/local/squid/sbin/squid - > /proc/sys/fs/file--HSn    
/usr/local/squid/sbin/squid

*取得squid运行状态信息： squidclient -p 80 mgr:info

*取得squid内存使用情况： squidclient -p 80 mgr:mem

*取得squid已经缓存的列表： squidclient -p 80 mgr:objects. use it carefully,it may crash

*取得squid的磁盘使用情况： squidclient -p 80 mgr:diskd

缓存的清理脚本

#!/bin/==-a -r $ $squidcache_path

下面是3.1的安装，针对需要3.1部分模块的朋友，但是不推荐用3.1 

tar -zxvf squid-.---.--/configure --prefix=/usr/local/squid --enable--io= --disable-delay-pools --disable-mem-gen-trace --disable-useragent-log --enable-kill-parent-hack --disable-arp-acl --enable-epoll --disable-ident-lookups --enable-snmp --enable-large-cache-files --with-large-&&-g squid -s /sbin/-R squid /usr/local/squid/-p //-p //-R //cache //-R  //cache ///usr/local/squid/etc/squid.conf /usr/local/squid/etc//usr/local/squid/etc/. sibling  . sibling  . sibling  -. parent   no-query originserver round-robin  name=. parent   no-query originserver round-robin  name=--bin ?-i ^https:\\ ?-i cgi-bin \?-i ^/usr/local/squid//logs//usr/local/squid//logs///cache      #设定缓存目录cache，目录容量最大1024M，*//squid      #设定缓存目录squid，目录容量最大3072M，*%以上时，新的内容将取代旧的内容，直到空间又下降到90%
/usr/local/squid/sbin/squid -/usr/local/squid/sbin/squid

配置lvs客户端模式

#!/bin/=./etc/rc.d/init.d/   $SNS_VIP netmask ./sbin/route add -host $SNS_VIP dev lo: >/proc/sys/net/ipv4/conf/lo/ >/proc/sys/net/ipv4/conf/lo/ >/proc/sys/net/ipv4/conf/all/ >/proc/sys/net/ipv4/conf/all/>/dev/ >& >/proc/sys/net/ipv4/conf/lo/ >/proc/sys/net/ipv4/conf/lo/ >/proc/sys/net/ipv4/conf/all/ >/proc/sys/net/ipv4/conf/all/*

lnmp自动安装脚本，含有eaccelerator memcache组件

这个是完整的配置脚本，可以把mysql部分取消~

版本我选择的是

pcre-8.01.tar.gz,  nginx-1.0.2.tar.gz,  mysql-5.1.41.tar.gz,   php-5.3.3.tar.bz2,   memcache-2.2.5.tgz

memcached 缓存安装配置：

mysql安装配置，已开启了indodb的支持
