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
#默认配置文件所在位置 /etc/my.cnf

#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;
+--------------------+
| Database |
+--------------------+
| information_schema |
| MysqL |
| performance_schema |
| test |
+--------------------+
#进入MysqL数据库
MysqL> use MysqL;
#查看MysqL数据库下所有的表
MysqL> show tables;
#查看用户表用户及密码
MysqL> select user,password,host from user;
+------+----------+-----------+
| user | password | host |
+------+----------+-----------+
| root | | localhost |
| root | | csxf |
| root | | 127.0.0.1 |
| root | | ::1 |
| | | localhost |
| | | csxf |
+------+----------+-----------+
#修改ROOT用户密码
MysqL> update user set password=password('root') where user='root';
#刷新缓存
MysqL> flush privileges;
#设置root用户远程连接权限
MysqL> grant all privileges on *.* to root@"%" identified by 'root' with grant option;
