1,调整最大文件数限制
ulimit -n
1024 #这个是默认值
echo ulimit -n 65535 >>/etc/profile
source /etc/profile #加载修改后的profile
ulimit -n #显示65535，修改完毕！
2,修改IO调度器设置
[root@mysql support-files]# cat /sys/block/sda/queue/scheduler
noop anticipatory [deadline] cfq #采用deadline的io调度器,重启后失效
title CentOS (2.6.32-220.el6.x86_64)
root (hd0,0)
kernel /boot/vmlinuz-2.6.32-220.el6.x86_64 ro root=UUID=5b4002c7-52b5-4749-8d87-ac61bacd0c8d rd_NO_LUKS rd_NO_LVM LANG=en_US .UTF-8 rd_NO_MD quiet SYSFONT=latarcyrheb-sun16 elevator=deadline numa=off rhgb crashkernel=auto KEYBOARDTYPE=pc KEYTABLE=us rd_NO_
DM
initrd /boot/initramfs-2.6.32-220.el6.x86_64.img #修改IO调度器和关闭numa,修改内核启动参数
3,修改swappiness设置
vi /etc/sysctl.conf
vm.swappiness = 0
sysctl -p
4,磁盘分区及文件类型
/ 根分区采用ext4
/opt 采用xfs
查看磁盘分区的文件类型
[root@mysql ~]# parted
GNU Parted 2.1

6,手工安装gcc
rpm -ivh gcc-4.4.6-3.el6.x86_64.rpm cloog-ppl-0.15.7-1.2.el6.x86_64.rpm cpp-4.4.6-3.el6.x86_64.rpm glibc-devel-2.12-1.47.el6.x86_64.rpm \

手工安装gcc-c++
rpm -ivh gcc-c++-4.4.6-3.el6.x86_64.rpm libstdc++-devel-4.4.6-3.el6.x86_64.rpm
tar xzvf cmakeXXXXX
tar zxvf percornaxxxxx
安装cmake
cd ~/cmake
./bootstrap
#检查无误后安装
make && make install
检查是否安装成功：
输入shell命令: cmake --version
给出一下信息表示安装成功：cmake version 2.8.10.2
cmake 会默认安装在 /usr/local/bin 下面
要改变安装路径，在bootstrap命令中加入'--prefix=PATH'选项。

Installing MySQL system tables...OK
Filling help tables...OK
To start mysqld at boot time you have to copy
support-files/mysql.server to the right place for your system
PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands:
/opt/mysql/bin/mysqladmin -u root password 'new-password'
/opt/mysql/bin/mysqladmin -u root -h mysql password 'new-password'
Alternatively you can run:
/opt/mysql/bin/mysql_secure_installation
which will also give you the option of removing the test
databases and anonymous user created by default. This is
strongly recommended for production servers.
See the manual for more instructions.
You can start the MySQL daemon with:
cd . ; /opt/mysql/bin/mysqld_safe &
You can test the MySQL daemon with mysql-test-run.pl
cd mysql-test ; perl mysql-test-run.pl
