CentOS6.5二进制文件安装MySQL5.6.39

准备工作
MySQ二进制安装Lmysql-5.6.39-linux-glibc2.12-x86_64.tar.gz 准备( 官网下载 )

一、检查是否安装过MySQL并卸载
# 检查是否安装过MySQL
[root@csxf ~]# rpm -qa|grep mysql
# 删除所有MySQL
[root@csxf ~]# yum -y remove mysql*
二、上传镜像文件至：/usr/local，解压，移动
[root@csxf ~]# su - root

[root@csxf ~]# cd /usr/local/
[root@csxf local]# tar -xzvf mysql-5.6.39-linux-glibc2.12-x86_64.tar.gz
[root@csxf local]# mv mysql-5.6.39-linux-glibc2.12-x86_64/ mysql

三、添加MySQL用户和组赋予权限
#添加mysql用户和组
[root@csxf ~]# groupadd -g 101 dba
[root@csxf ~]# useradd -u 514 -g dba -G root -d /usr/local/mysql mysqladmin
[root@csxf ~]# id mysqladmin
#添加环境变量
[root@csxf local]# cp /etc/skel/.* /usr/local/mysql

四、配置my.cnf及修改权限

#修改my.cnf文件权限
[root@csxf local]# chown mysqladmin:dba /etc/my.cnf
[root@csxf local]# chmod 640 /etc/my.cnf
#修改MySQL安装目录权限
[root@csxf local]# chown -R mysqladmin:dba /usr/local/mysql
[root@csxf local]# chmod -R 755 /usr/local/mysql
#切换mysqladmin用户，准备安装
[root@csxf local]# su - mysqladmin
[mysqladmin@csxf ~]$ pwd
/usr/local/mysql
[mysqladmin@csxf ~]$ mkdir arch

五、数据库初始化
#切换MySQL用户数据库初始化
[mysqladmin@csxf ~]$ scripts/mysql_install_db --user=mysqladmin --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data
#可能出现错误
Installing MySQL system tables..../bin/mysqld: error while loading shared libraries: libaio.so.1: cannot open shared object file: No such file or directory
#缺少libaio.so 包
[root@sht-sgmhadoopnn-01 local]# yum -y install libaio
#可能出现错误
"/usr/bin/perl: bad interpreter: No such file or directory"
#缺少 perl 环境
[root@csxf mysql]# yum -y install perl perl-devel
[root@csxf mysql]# yum install -y perl-Data-Dumper
出现报错根据错误实际情况处理
#删除自带my.cnf文件
[mysqladmin@csxf ~]$ rm -rf my.cnf

六、MySQL服务配置
#ROOT 用户创建服务复制到init.d服务下，方便启动和停止
[root@csxf mysql]# cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysql
#赋予可执行权限
[root@csxf ~]# chmod +x /etc/init.d/mysql
#删除服务
[root@csxf ~]# chkconfig --del mysql
#添加服务
[root@csxf ~]# chkconfig --add mysql
[root@csxf ~]# chkconfig --level 345 mysql on
[root@csxf ~]# chkconfig --list mysql
mysql 0:off 1:off 2:on 3:on 4:on 5:on 6:off

六、MySQL启动服务
[root@csxf local]# su - mysqladmin
[mysqladmin@csxf ~]$ bin/mysqld_safe &
[1] 10596
180508 17:21:55 mysqld_safe Logging to '/usr/local/mysql/data/hostname.err'.
180508 17:21:55 mysqld_safe Starting mysqld daemon with databases from /usr/local/mysql/data
.....按回车键

#查看是否启动成功
[mysqladmin@csxf ~]$ ps -ef|grep mysql
root 10420 10210 0 16:52 pts/0 00:00:00 su - mysqladmin
root 10550 10519 0 17:12 pts/0 00:00:00 su - mysqladmin
514 10596 10551 0 17:21 pts/0 00:00:00 /bin/sh bin/mysqld_safe
514 11239 10596 1 17:21 pts/0 00:00:00 /usr/local/mysql/bin/mysqld --basedir=/usr/local

七、登录及基本操作

#启动数据库
service mysql start/stop/status/restart

# 首次登录

[mysqladmin@csxf ~]$ mysql
#查看所有数据库
mysql> show databases;

#进入mysql数据库
mysql> use mysql;
#查看mysql数据库下所有的表
