1.安装介质
http://dev.mysql.com/downloads/mysql/
2.安装过程
2.1主机配置
a)关闭防火墙
service iptables stop
b)禁掉Selinux
vim /etc/selinux/config
#SELINUX=enforcing
#SELINUXTYPE=targeted
SELINUX=disabled
setenforce 0
2.2修改limits.conf
vi /etc/security/limits.conf
mysql soft nproc 16384
mysql hard nproc 16384
mysql soft nofile 65536
mysql hard nofile 65536
mysql soft stack 10240
2.3添加pam_limits.so模块
在文件最下面加入以下内容：
vi /etc/pam.d/login
session required pam_limits.so
2.4配置内核参数
vi /etc/sysctl.conf
fs.aio-max-nr = 1048576
fs.file-max = 6815744
kernel.shmall = 16777216
kernel.shmmax = 68719476736
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
net.core.rmem_default = 262144
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 1048576
net.ipv4.ip_local_port_range = 9000 65500
net.ipv4.tcp_tw_reuse = 1
net.ipv4.tcp_tw_recycle = 1
net.ipv4.tcp_syncookies=1
net.ipv4.tcp_fin_timeout = 30
使修改的内核参数生效
sysctl -p
确保当前系统没有mysql相关的包
rpm -aq|grep -i mysql
2.5创建安装目录
查看磁盘的挂载情况
umount /home
mkdir /u01
vi /etc/fstab
修改:
/dev/mapper/VolGroup-lv_home /u01
mount /dev/mapper/VolGroup-lv_home /u01
mkdir /u01/db
2.6创建mysql用户
useradd -u 601 -d /u01/db/mysql -s /bin/bash mysql
uid=601(mysql) gid=601(mysql) groups=601(mysql)
2.7解压安装文件
红色字体的命令是在一台机器上安装完之后,在另外一台机器上直接scp过去的
root@192.168.1.243:/u01/db/mysql/
scp mysql-5.6.29-linux-glibc2.5-x86_64.tar root@192.168.1.243:/u01/db/mysql/
将mysql-5.6.29-linux-glibc2.5-x86_64.tar.gz和MySQL-shared-compat-5.6.33-1.linux_glibc2.5.x86_64.rpm上传至/u01/db/mysql下并解压
gunzip mysql-5.6.29-linux-glibc2.5-x86_64.tar.gz
tar -xvf mysql-5.6.29-linux-glibc2.5-x86_64.tar
ln -s mysql-5.6.29-linux-glibc2.5-x86_64 mysql
2.8配置mysql的环境变量
vi ~/.bash_profile
增加：
PATH=$HOME/mysql/bin:$HOME/mysql/support-files:$PATH
[mysql@localhost ~]$ source ~/.bash_profile
[mysql@localhost ~]$ which mysql
~/mysql/bin/mysql
2.9修改 mysql.server文件
vi ~/mysql/support-files/mysql.server
修改:
basedir=/u01/db/mysql/mysql
datadir=/u01/db/mysql/mydata
ln -s ~/mysql/support-files/mysql.server ~/mysql/bin
cd ~/mysql
scripts/mysql_install_db --basedir=/u01/db/mysql/mysql --datadir=/u01/db/mysql/mydata
cd /u01/db/mysql/mysql/
support-files/mysql.server start
删除测试数据库（test）和匿名用户
/u01/db/mysql/mysql/bin/mysql_secure_installation
第一个命令按enter,之后密码是123456,之后全是y
mysql.server stop
cd $HOME
mkdir conf log_bin logs log_relay scripts sh
vi conf/my.cnf
修改server_id的值,每台机器要设置为唯一值,将下面这段整段复制过去
#GERNERAL
port = 3306
user = mysql
server_id = 4303
character_set_server = utf8
basedir = /u01/db/mysql/mysql

[mysqladmin]
user=root
password=123456
ln -s conf/my.cnf .my.cnf
mysql.server start
增加root用户远程连接
mysql>
grant all privileges on *.* to 'root'@'%' identified by '123456' with grant option;
flush privileges;
通过远程连接测试
mysql -uroot -p -h 192.168.1.249
