1 MySQL二进制部署 2018-05-04

1.数据库类型

关系型：Oracle、MySQL、PostgreSQL
NOSQL：HBASE、Redis
图形：Titan
时序型：infuxdb

2.将mysql安装包发送到centOS /usr/local目录下

[root@sht-sgmhadoopnn-01 ~]# cd /usr/local
[root@sht-sgmhadoopnn-01 local]# rz mysql-5.6.23-linux-glibc2.5-x86_64.tar.gz

3.检查是否已安装

[root@sht-sgmhadoopnn-01 local]# ps -ef|grep mysqld
root 2493 2423 0 19:48 pts/3 00:00:00 grep mysqld
[root@sht-sgmhadoopnn-01 local]# rpm -qa |grep -i mysql

4.解压、重命名

[root@sht-sgmhadoopnn-01 local]# tar xzvf mysql-5.6.23-linux-glibc2.5-x86_64.tar.gz
[root@sht-sgmhadoopnn-01 local]# mv mysql-5.6.23-linux-glibc2.5-x86_64 mysql

5.创建组和用户

[root@sht-sgmhadoopnn-01 local]# groupadd -g 101 dba
[root@sht-sgmhadoopnn-01 local]# useradd -u 514 -g dba -G root -d /usr/local/mysql mysqladmin
[root@sht-sgmhadoopnn-01 local]# id mysqladmin
uid=514(mysqladmin) gid=101(dba) groups=101(dba),0(root)
[root@sht-sgmhadoopnn-01 local]# passwd mysqladmin 设置密码

if user mysqladmin is existing,please execute the following command of usermod.
[root@sht-sgmhadoopnn-01 local]# usermod -u 514 -g dba -G root -d /usr/local/mysql mysqladmin #

6.copy 环境变量配置文件至mysqladmin用户的home目录中

[root@sht-sgmhadoopnn-01 local]# cp /etc/skel/.* /usr/local/mysql

7.修改 /etc/my.cnf(640)

[root@sht-sgmhadoopnn-01 ~]# vi /etc/my.cnf
使用下面内容覆盖原先内容

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

basedir     = /usr/local/mysql
datadir     = /usr/local/mysql/data
pid-file     = /usr/local/mysql/data/hostname.pid

innodb_data_home_dir = /usr/local/mysql/data/
innodb_data_file_path = ibdata1:500M:autoextend
innodb_log_group_home_dir = /usr/local/mysql/arch
innodb_log_files_in_group = 2
innodb_log_file_size = 200M

innodb_buffer_pool_size = 2048M

[myisamchk]
key_buffer_size = 256M
sort_buffer_size = 256M
read_buffer = 2M

确保innodb_buffer_pool_size = 2048M 大于1G

8.赋权限

[root@sht-sgmhadoopnn-01 local]# chown mysqladmin:dba /etc/my.cnf
[root@sht-sgmhadoopnn-01 local]# chmod 640 /etc/my.cnf
[root@sht-sgmhadoopnn-01 etc]# ll my.cnf
-rw-r----- 1 mysqladmin dba 2201 Aug 25 23:09 my.cnf

[root@sht-sgmhadoopnn-01 local]# chown -R mysqladmin:dba /usr/local/mysql
[root@sht-sgmhadoopnn-01 local]# chmod -R 755 /usr/local/mysql
[root@sht-sgmhadoopnn-01 local]# su - mysqladmin
[mysqladmin@sht-sgmhadoopnn-01 ~]$ pwd
/usr/local/mysql

9.第一次安装

[mysqladmin@sht-sgmhadoopnn-01 ~]$ mkdir arch
[mysqladmin@sht-sgmhadoopnn-01 ~]$ scripts/mysql_install_db --user=mysqladmin --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data

10.配置 mysql 服务 and 设置开机自启

[root@sht-sgmhadoopnn-01 ~]# cd /usr/local/mysql
[root@sht-sgmhadoopnn-01 mysql]# cp support-files/mysql.server /etc/rc.d/init.d/mysql 将服务文件拷贝到init.d下，并重命名为mysql
[root@sht-sgmhadoopnn-01 mysql]# chmod +x /etc/rc.d/init.d/mysql 赋予可执行权限
[root@sht-sgmhadoopnn-01 mysql]# chkconfig --del mysql 删除服务
[root@sht-sgmhadoopnn-01 mysql]# chkconfig --add mysql 添加服务
[root@sht-sgmhadoopnn-01 mysql]# chkconfig --level 345 mysql on 设置开机自启

11.开启服务

[root@sht-sgmhadoopnn-01 mysql]# su - mysqladmin
[mysqladmin@sht-sgmhadoopnn-01 ~]$ pwd
/usr/local/mysql
[mysqladmin@sht-sgmhadoopnn-01 ~]$ rm -rf my.cnf
[mysqladmin@sht-sgmhadoopnn-01 ~]$ bin/mysqld_safe & 不要忘记，按回车键

[root@rzdatahadoop001 lib]# rpm --nodeps -e mysql-libs-5.1.71-1.el6.x86_64 先卸载

12.服务相关信息

[mysqladmin@sht-sgmhadoopnn-01 ~]$ ps -ef|grep mysqld 查看服务
[mysqladmin@sht-sgmhadoopnn-01 ~]$ netstat -tulnp | grep mysql 查看端口号
[mysqladmin@sht-sgmhadoopnn-01 ~]$ mysql 登录
mysql> show databases; 查看数据库
