1.安裝介質

2.安裝過程

2.1主機配置

a)關閉防火牆

service iptables stop

 chkconfig iptables off

 chkconfig --list iptables

iptables            0:off       1:off       2:off       3:off       4:off       5:off       6:off

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新增pam_limits.so模組

在檔案最下面加入以下內容：

vi /etc/pam.d/login

session required pam_limits.so

2.4配置核心引數

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

使修改的核心引數生效

sysctl -p

確保當前系統沒有mysql相關的包

rpm -aq|grep -i mysql

rpm -e xxxx  --nodeps

2.5建立安裝目錄

檢視磁碟的掛載情況

df -h   

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建立mysql使用者

useradd -u 601 -d /u01/db/mysql -s /bin/bash mysql

passwd mysql       #設定mysql使用者的密碼為mysql

 [[email protected] ~]# id mysql

uid=601(mysql) gid=601(mysql) groups=601(mysql)

2.7解壓安裝檔案

紅色字型的命令是在一臺機器上安裝完之後,在另外一臺機器上直接scp過去的

 MySQL-shared-compat-5.6.33-1.linux_glibc2.5.x86_64.rpm [email protected]:/u01/db/mysql/

su – mysql

將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上傳至/u01/db/mysql下並解壓

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的環境變數

vi ~/.bash_profile

增加：

PATH=$HOME/mysql/bin:$HOME/mysql/support-files:$PATH

[[email protected] ~]$ source ~/.bash_profile

[[email protected] ~]$ which mysql

~/mysql/bin/mysql

2.9修改 mysql.server檔案

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

刪除測試資料庫（test）和匿名使用者

/u01/db/mysql/mysql/bin/mysql_secure_installation

第一個命令按enter,之後密碼是123456,之後全是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,每臺機器要設定為唯一值,將下面這段整段複製過去

[client] 

port = 3306 

socket = /tmp/mysql.sock 

[mysqld] 

#GERNERAL

[mysqladmin]

user=root

ln -s conf/my.cnf .my.cnf

mysql.server start

增加root使用者遠端連線

mysql>

grant all privileges on *.* to 'root'@'%' identified by '123456' with grant option;

flush privileges;

通過遠端連線測試

mysql -uroot -p -h 192.168.1.249
