——安装MySQL
1）创建mysql用户
# mysql -M -s /sbin/nologin mysql 2）安装软件所需依赖包
# yum install gcc gcc-c++ autoconf automake ncurses-devel libtool-ltdl-devel* libaio libaio-devel -y 3）解压安装MySQL [这里下载的是免安装版本]
# tar fzvx mysql-5.6.16-linux-x86_64.tar.gz -C /usr/local/
# mv mysql-5.6.16-linux-x86_64 mysql
# cd mysql/
# chown -R root:mysql .
# chown -R mysql:mysql data/
# ./scripts/mysql_install_db --user=mysql \
> --basedir=/usr/local/mysql/ \
> --datadir=/usr/local/mysql/data/
WARNING: The host 'master' could not be looked up with /usr/local/mysql//bin/resolveip.
This probably means that your libc libraries are not 100 % compatible
with this binary MySQL version. The MySQL daemon, mysqld, should work
normally with the exception that host name resolving will not work.
This means that you should use IP addresses instead of hostnames
when specifying MySQL privileges !

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:
/usr/local/mysql//bin/mysqladmin -u root password 'new-password'
/usr/local/mysql//bin/mysqladmin -u root -h master password 'new-password'
Alternatively you can run:
/usr/local/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 . ; /usr/local/mysql//bin/mysqld_safe &
You can test the MySQL daemon with mysql-test-run.pl
cd mysql-test ; perl mysql-test-run.pl
Please report any problems at http://bugs.mysql.com/
The latest information about MySQL is available on the web at
http://www.mysql.com
Support MySQL by buying support/licenses at http://shop.mysql.com
New default config file was created as /usr/local/mysql//my.cnf and
will be used by default by the server when you start it.
You may edit this file to change server settings
WARNING: Default config file /etc/my.cnf exists on the system
This file will be read by default by the MySQL server
If you do not want to use this, either remove it, or use the
--defaults-file argument to mysqld_safe when starting the server. 4）复制配置文件并设置启动脚本
# cp my.cnf /etc/my.cnf
cp：是否覆盖"/etc/my.cnf"？ y
# cp support-files/mysql.server /etc/init.d/mysqld# chmod +x /etc/init.d/mysqld
# chkconfig --add mysqld
# chkconfig mysqld on 5）开启二进制日志
# mkdir /usr/local/mysql/logs
# chown -R mysql:mysql /usr/local/mysql/logs/
# vi /etc/my.cnf
#开启二进制日志
log-bin = /usr/local/mysql/logs/sql-bin
#唯一编号 [一般取IP的后两位]
server_id = 10 6）设置MySQL环境变量
# vi /etc/profile.d/mysql.sh
PATH=$PATH:/usr/local/mysql/bin:
# source /etc/profile 7）启动MySQL
# service mysqld start
Starting MySQL............ SUCCESS!
# netstat -antup |grep 3306
tcp 0 0 :::3306 :::* LISTEN 1768/mysqld
#salve步骤一样，这里省略... ——主从复制
1）在master上的MySQL创建相关用户

1）创建相关用户和组
# groupadd -g 3306 mysql-proxy
# useradd -u 3306 -g mysql-proxy -s /sbin/nologin -M mysql-proxy 2）编译安装mysql-proxy
# cd /Linux/
# tar zfvx mysql-proxy-0.8.3-linux-rhel5-x86-64bit.tar.gz -C /usr/local/
# mv mysql-proxy-0.8.3-linux-rhel5-x86-64bit/ mysql-proxy
# cd mysql-proxy/
# chown -R root:mysql-proxy . 3）设置mysql-proxy环境变量
# vi /etc/profile.d/mysql-proxy.sh
export PATH=$PATH:/usr/local/mysql-proxy/bin
# source /etc/profile 4）启动mysql-proxy
# mysql-proxy --daemon --log-level=debug \
