Centos 6.5下源码安装MySql5.6数据库

一、安装前的准备：

1、安装环境

操作系统：CentOS-6.5-x86_64

2、所需软件

jdk-8u45-linux-x64.gz

mysql-5.6.23-linux-glibc2.5-x86_64.tar.gz

3、上传并安装部署jdk

3.1、上传安装文件

3.2、查看系统当前的jdk版本：

java -vesion

3.3、建立jdk的安装目录并移动安装文件到当前目录：

mkdir   -p /usr/java   

mv /usr/local/jdk-8u45-linux-x64.gz ./

ll

3.4、解压安装文件：

tar -xzvf jdk-8u45-linux-x64.gz

3.5、解压后查看目录并修改权限：

ll

chown -R root:root    jdk1.8.0_45

3.6、编辑并配置全局环境变量

vim /etc/profile

export  JAVA_HOME=/usr/java/jdk1.8.0_45
export PATH=$JAVA_HOME/bin:$PATH

which java

source /etc/profile

二、安装步骤

1、进入目录/usr/local：

cd /usr/local

2、上传安装文件：

3、检测是否安装mysql：

4、解压安装文件并重命名

cd /usr/local

ll

tar xzvf mysql-5.6.23-linux-glibc2.5-x86_64.tar.gz

mv mysql-5.6.23-linux-glibc2.5-x86_64 mysql

5、创建用户和组

groupadd -g 101 dba

useradd -u 514 -g dba -G root -d /usr/local/mysql mysqladmin

id mysqladmin

6、修改mysqladmin用户密码及配置环境变量

密码为oracle

passwd mysqladmin

cp /etc/skel/.* /usr/local/mysql

7、创建/etc/my.cnf文件

vi /etc/my.cnf

[client]
port            = 3306
socket          = /usr/local/mysql/data/mysql.sock
 
[mysqld]
port            = 3306
socket          = /usr/local/mysql/data/mysql.sock

8、修改/etc/my.cnf文件的用户和所属组

chown  mysqladmin:dba /etc/my.cnf

chmod  640 /etc/my.cnf

ll my.cnf

chown -R mysqladmin:dba /usr/local/mysql

chmod -R 755 /usr/local/mysql

su - mysqladmin

pwd

9、创建归档

mkdir arch

10、开始第一次安装：

scripts/mysql_install_db  --user=mysqladmin --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data

11、到root用户下，添加服务到开机自启动：

su - root

cd /usr/local/mysql

cp support-files/mysql.server /etc/rc.d/init.d/mysql

chmod +x /etc/rc.d/init.d/mysql

chkconfig --add mysql

chkconfig --level 345 mysql on

12、切入mysqladmin用户，启动安全模式

su - mysqladmin

 pwd

rm -rf my.cnf

bin/mysqld_safe &

13、查看MySql是否在后台运行及端口号：

 ps -ef|grep mysqld

service mysql status

netstat -tulnp | grep mysql

三、登录MySql数据库并进行简单的命令操作：

1、登录MySql数据库

2、查看当前有哪些库：
