--linux 基础配置  指定机器名为sql1

--查看centos内核
uname -a
cat /etc/issue

--修改机器名

1、 echo "192.168.33.190 sql1 localhost.localdomain localhost4 localhost4.localdomain4" >> /etc/hosts

2、 vi /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=sql1

--修改ip
vi /etc/sysconfig/network-scripts/ifcfg-eth0

DEVICE="eth0"
BOOTPROTO="static"
HWADDR="00:0C:29:39:E0:20"
NM_CONTROLLED="yes"
ONBOOT="yes"
TYPE="Ethernet"
UUID="78bfd5ef-0ba2-4fff-aba3-bf8d7839fcb9"
IPADDR="192.168.33.190"
GATEWAY="192.168.33.1"
DNS1=180.76.76.76

--关闭selinux
vi /etc/sysconfig/selinux
SELINUX=disabled

--关闭防火墙
service iptables stop
chkconfig iptables off

--配置本地yum源 卸载 umount /mnt/cdrom
mkdir /mnt/cdrom
mount /dev/cdrom /mnt/cdrom

cd /etc/yum.repos.d
其下所有文件，进行重命名；新建CentOS-Media.repo

vi CentOS-Media.repo
[c6-media]
name=CentOS-$releasever - Media
baseurl=file:///mnt/cdrom/
gpgcheck=1
enabled=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6

yum clean all --清理yum缓存

yum install php --安装php测试

如需要将yum源改为网络，还原/etc/yum.repos.d目录下的四个文件即可

--查看是否已安装
rpm -qa | grep mysql
mysql-libs-5.1.61-4.el6.x86_64

--卸载mysql
rpm -e mysql-libs --直接删除会失败
rpm --nodeps -e mysql-libs

--编译安装需要的包
yum -y install make
yum -y install gcc-c++
yum -y install cmake
yum -y install bison-devel
yum -y install ncurses-devel

--创建mysql用户和组
groupadd mysql
useradd -g mysql mysql

--设置用户的操作系统资源限制
vi /etc/security/limits.conf
mysql soft nproc 2047
mysql hard nproc 16384
mysql soft nofile 1024
mysql hard nofile 65536
