CentOS 6.8 数据库安装5.5.32
1:安装数据库
1)检查版本,内核
[root@mysql1 ~]# cat /etc/redhat-release
CentOS release 6.8 (Final)
[root@mysql1 ~]# una
unalias uname
[root@mysql1 ~]# uname -r
2.6.32-642.el6.x86_64
[root@mysql1 ~]# uname -m
x86_64
2)创建文件夹
[root@mysql1 ~]# cd /home/hubo/tools
-bash: cd: /home/hubo/tools: 没有那个文件或目录
[root@mysql1 ~]# mkdir -p /home/hubo/tools
3)上传软件包解压mysql-5.5.32.tar cmake-2.8.8.tar
[root@mysql1 tools]# ll
总用量 29580
-rw-r--r--. 1 root root 5691656 11月 30 21:08 cmake-2.8.8.tar.gz
-rw-r--r--. 1 root root 24596474 11月 30 21:08 mysql-5.5.32.tar.gz
[root@mysql1 tools]# tar xf cmake-2.8.8.tar.gz
4)安装cmake
[root@mysql1 tools]# cd cmake-2.8.8
[root@mysql1 cmake-2.8.8]# ./configure
报错
Log of errors: /home/hubo/tools/cmake-2.8.8/Bootstrap.cmk/cmake_bootstrap.log

开机启动mysql
[root@mysql1 tools]# chkconfig mysqld on
[root@mysql1 tools]# chkconfig --list mysqld
mysqld 0:关闭 1:关闭 2:启用 3:启用 4:启用 5:启用 6:关闭
===========================建立安装Mysql多实例,以Mysql 5.5为例===============================
1)安装好Mysql依赖包
yum install ncurses-devel -y
yum install libaio-devel -y
2)以root建立Msql账号和组(已完成)
groupadd mysql
useradd mysql -s /sbin/nologin -M -g mysql
3)获得Mysql软件:(已完成)
4)安装Mysql软件
1.解压软件包,移动到规范的软件安装目录。(已完成)
[root@mysql1 tools]# tar xf mysql-5.5.32.tar.gz
[root@mysql1 tools]# mkdir -p /application/
[root@mysql1 tools]# mv mysql-5.5.32-linux6.8-x86_64 /application/mysql-5.5.32
2.生成不带版本号的软链接/application/mysql,即mysql安装路径
[root@mysql1 tools]# ln -s /application/mysql-5.5.32/ /application/mysql
5)创建Mysql多实例的数据文件目录
我们采用/data 目录作为mysql多实例总的根目录
先把进程关掉
[root@mysql1 ~]# pkill mysqld
[root@mysql1 ~]# ps -ef|grep mysql
root 4341 1709 0 04:07 pts/0 00:00:00 grep mysql
干掉启动命令
[root@mysql1 ~]# rm -f /etc/init.d/mysqld
创建3306,33072个目录
[root@mysql1 ~]# mkdir -p /data/{3306,3307}/data
看下2个目录结构
[root@mysql1 ~]# tree /data/
/data/ <===总的多实例根目录
├── 3306 <===3306实例的目录
│ └── data <===3306实例的数据文件目录
└── 3307 <===3307实例的目录
└── data <===3307实例的数据文件目录
创建Mysql多实例的配置文件
上传包到cd /home/hubo/tools/
[root@mysql1 ~]# cd /home/hubo/tools/
[root@mysql1 tools]# unzip data.zip
Archive: data.zip
creating: data/
creating: data/3306/

inflating: data/3306/mysql
creating: data/3307/

inflating: data/3307/mysql
拷贝文件
[root@mysql1 tools]# cp data/3306/my.cnf /data/3306/
[root@mysql1 tools]# cp data/3307/my.cnf /data/3307/
[root@mysql1 tools]# tree /data/

创建Mysql多实例的启动文件
inflating: data/3307/mysql
拷贝文件脚本
[root@mysql1 tools]# cp data/3306/mysql /data/3306/
[root@mysql1 tools]# cp data/3307/mysql /data/3307/
[root@mysql1 tools]# tree data

授权
[root@mysql1 tools]# chown -R mysql.mysql /data
[root@mysql1 tools]# find /data/ -type f -name "mysql"|xargs ls -l

-rwxr-xr-x. 1 mysql mysql 1305 12月 1 05:52 /data/3307/mysql
配置Mysql命令全局使用路径
配置环境变量
[root@mysql1 ~]# vim /etc/profile
export PATH=/application/mysql/bin:$PATH
[root@mysql1 ~]# source /etc/profile
初始化Mysql多实例的数据库文件
[root@mysql1 tools]# cd /application/mysql/scripts
