腾讯云初始化

1. 硬盘初始化

http://www.qcloud.com/wiki/Linux系统格式化小于2TB数据盘操作指引

fdisk -l，查看数据盘信息，包括未分区硬盘
fdisk /dev/vdb
依次输入“n”(新建分区)、“p”(新建扩展分区)、“1”(使用第1个主分区)，两次回车(使用默认配置)，输入“w”(保存分区表)，开始分区。

mkfs.ext3 /dev/vdb1
返回根目录
mkdir /mydata
mount /dev/vdb1 /mydata
echo '/dev/vdb1 /mydata ext3 defaults 0 0' >> /etc/fstab

df -h
说明：重装系统后，无需再重新分区，直接进入格式化，mkfs.ext3 /dev/vdb1

2. 安全加固
   http://bbs.qcloud.com/forum.php?mod=viewthread&tid=4480

wget http://mirrors.tencentyun.com/install/sec/vpcagent-X64.zip
unzip vpcagent-X64.zip
sh install64.sh

检查：/usr/local/sa/agent/check.sh

3. yum 源
   mv /etc/yum.repos.d/base.repo /etc/yum.repos.d/base.repo.backup
   wget http://mirrors.163.com/.help/CentOS6-Base-163.repo
   yum clean all
   yum makecache

yum updatcd

http://mirrors.163.com/.help/centos.html

6. MySQL

检查，rpm -qa | grep -i mysql
强制卸载 默认的mysql 5.1， rpm -e --nodeps mysql-libs-5.1.*，
http://zfy421.iteye.com/blog/1960247

卸载 mariadb
rpm -e —nodeps
http://www.jb51.net/article/72397.htm

yum install glibc

wget http://mirrors.sohu.com/mysql/MySQL-5.5/MySQL-server-5.5.46-1.linux2.6.x86_64.rpm
wget http://mirrors.sohu.com/mysql/MySQL-5.5/MySQL-client-5.5.46-1.linux2.6.x86_64.rpm
wget http://mirrors.sohu.com/mysql/MySQL-5.5/MySQL-devel-5.5.46-1.linux2.6.x86_64.rpm

rpm -ivh MySQL-server-5.5.46-1.linux2.6.x86_64.rpm

cp /usr/share/mysql/my-medium.cnf /etc/my.cnf，改名为my.cnf作为mysql配置文件。

http://www.myexception.cn/operating-system/629986.html

更改mysql 目录到 数据盘
mv /var/lib/mysql　/mydata/mysql/data/
chown -R mysql:mysql /mydata/mysql/data/
chmod -R 755 /mydata/mysql/data/
chmod -R 755 /mydata/mysql/data/mysql
chmod -R 755 /mydata/mysql/data/test
chmod -R 755 /mydata/mysql/data/performance_

修改 /etc/my.cnf，/etc/init.d/mysql, /usr/bin/mysqld_safe

[client]
default-character-set=utf8
socket=/mydata/mysql/data/mysql.sock

[mysqld]
port=3306
socket=/mydata/mysql/data/mysql.sock
character_set_server=utf8
max_allowed_packet = 16M

socket　 = /var/lib/mysql/mysql.sock
datadir=/var/lib/mysql

ln -s /home/data/mysql/mysql.sock /var/lib/mysql/mysql.sock

grant all privileges ON . TO 'root'@'%' IDENTIFIED BY 'a123456' WITH GRANT OPTION;

字符集
SHOW VARIABLES LIKE ‘character%’;

默认编码：a123456

代理配置

wget http://www.boutell.com/rinetd/http/rinetd.tar.gz

vi /etc/rc.d/rc.local
/usr/sbin/rinetd -c /etc/rinetd.conf

端口转发：rinetd，http://www.boutell.com/rinetd/
配置：http://blog.sina.com.cn/s/blog_695d0b300101bdan.html
rinetd -c /etc/rinetd.conf

安装：
mkdir /usr/man/man8
http://www.linuxidc.com/Linux/2013-01/77794.htm

配置文件：
vi /etc/rinetd.conf

需要确认进程中没有rinetd，如果有的话，需要删除该进程：pkill rinetd
ps ax|grep rinetd
