新建a.sh文件,复制粘贴以上内容到文件中,运行sh a.sh
2. 对TCP/IP网络参数进行调整
echo 'net.ipv4.tcp_syncookies = 1' >> /etc/sysctl.conf
sysctl -p
3. 修改shell命令的history 记录个数
vim /etc/profile
    HISTSIZE=100
4. 定时校正服务器时间
yum install ntp
crontab -e
    */5 * * * * ntpdate ntp.api.bz
5. 停止打印服务
/etc/rc.d/init.d/cups stop
chkconfig --list cups 确认是否关闭
6. 停止ipv6
ifconfig -a
vim /etc/modprobe.conf
    alias net -pf -10 off
    alias ipv6 off
echo "IPV6INIT = no " >> /etc/sysconfig/network-scripts/ifconfig-eth0
shutdown -r now
7. 调整linux 最大文件打开数
vim /etc/rc.local
ulimit -SHn 65535
8. 关闭写磁盘I/0功能
vim /etc/fstab
   /dev/sda5 /data/ ext3 noatime,nodiratime 0 0
9. 优化内核TCP参数
vim /etc/sysctl.conf
    net.ipv4.neigh.default.gc_stale_time = 120
    net.ipv4.conf.all.rp_filter = 0
    net.ipv4.conf.default.rp_filter = 0
    net.ipv4.conf.default.arp_announce = 2
    net.ipv4.conf.all.arp_announce = 2
    net.ipv4.tcp_max_tw_buckets = 5000
    net.ipv4.tcp_syncookies = 1
    net.ipv4.tcp_max_syn_backlog = 20000
    net.ipv4.tcp_synack_retries = 2
    net.ipv4.conf.lo.arp_announce=2
    net.ipv4.tcp_fin_timeout = 30
    net.ipv4.tcp_keepalive_time = 1200
    net.ipv4.tcp_tw_reuse = 1
    net.ipv4.tcp_tw_recycle = 1
    net.ipv4.ip_local_port_range = 1024 65000
sysctl -p
