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

[client]
port = 3306
socket = /usr/local/mysql/data/mysql.sock
[mysqld]
port = 3306
socket = /usr/local/mysql/data/mysql.sock
skip-external-locking
key_buffer_size = 256M
sort_buffer_size = 2M
read_buffer_size = 2M
read_rnd_buffer_size = 4M
query_cache_size= 32M
max_allowed_packet = 16M
myisam_sort_buffer_size=128M
tmp_table_size=32M
table_open_cache = 512
thread_cache_size = 8
wait_timeout = 86400
interactive_timeout = 86400
max_connections = 600
# Try number of CPU's*2 for thread_concurrency

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;
