Linux环境安装Mysql数据库的三种方式之一:二进制包方式安装
来源:互联网 发布:淘宝刷单91lingla 编辑:程序博客网 时间:2024/05/17 06:01
本文是在CentOS7系统平台下安装Mysql5.6.26版本数据库的操作说明,如有错误,请指正。
系统平台:CentOS-7-x86_64
数据库版本:mysql-5.6.26
Mysql镜像文件下载地址:http://dev.mysql.com/downloads/mirrors.html
本次演示的Mysql安装包版本:mysql-5.6.26-linux-glibc2.5-x86_64.tar.gz
1、添加mysql用户组及mysql用户
[root@localhost ~]# groupadd mysql[root@localhost ~]# useradd -r -g mysql mysql
2、将二进制文件解压到指定的安装目录:/usr/local/mysql
到mysql-5.6.26-linux-glibc2.5-x86_64.tar.gz包的目录下,解压到/usr/local目录下:
[root@localhost tmp]# tar zxvf mysql-5.6.26-linux-glibc2.5-x86_64.tar.gz -C /usr/local/
到/usr/local/目录中,重命名解压出来的目录名,改为mysql:
[root@localhost tmp]# cd /usr/local/[root@localhost local]# mv mysql-5.6.26-linux-glibc2.5-x86_64 mysql
查看此目录下文件:
[root@localhost local]# cd mysql/[root@localhost mysql]# lsbin data include lib mysql-test scripts sql-benchCOPYING docs INSTALL-BINARY man README share support-files
注:/usr/local/mysql/下的目录结构
Directory
Contents of Directory
bin
Client programs and the mysqld server
data
Log files, databases
docs
Manual in Info format
man
Unix manual pages
include
Include (header) files
lib
Libraries
scripts
mysql_install_db
share
Miscellaneous support files, including error messages, sample configuration files, SQL for database installation
sql-bench
Benchmarks
3、创建mysql数据存放的目录:/data/mysql
[root@localhost mysql]# mkdir -p /data/mysql
4、更改所属的组和用户
[root@localhost mysql]# chown -R mysql:mysql /usr/local/mysql/[root@localhost mysql]# chown -R mysql:mysql /data/mysql/
5、初始化mysql
注释:以mysql用户执行mysql_install_db脚本,基本目录为:/usr/local/mysql/,数据文件目录为:/data/mysql/

This isstrongly recommended for productionservers.See the manual for more instructions.You can start the MySQL daemon with: cd. ; /usr/local/mysql//bin/mysqld_safe &You can test the MySQL daemon withmysql-test-run.pl cdmysql-test ; perl mysql-test-run.plPlease report any problems athttp://bugs.mysql.com/The latest information about MySQL isavailable on the web at http://www.mysql.comSupport MySQL by buying support/licenses athttp://shop.mysql.comNew default config file was created as/usr/local/mysql//my.cnf andwill be used by default by the server whenyou start it.You may edit this file to change serversettingsWARNING: Default config file /etc/my.cnfexists on the systemThis file will be read by default by theMySQL serverIf you do not want to use this, eitherremove it, or use the--defaults-file argument to mysqld_safewhen starting the server
注:本次启动有一个报错如下:
FATAL ERROR: please install the followingPerl modules before executing ./scripts/mysql_install_db:
Data::Dumper
解决方案:
[root@localhost mysql]# yum install -yperl-Module-Install.noarch
6、修改my.cnf配置文件
复制/usr/local/mysql/support-files/my-default.conf 文件到/etc/ 目录下,覆盖原有的配置文件mysql/my.cnf:
[root@localhost mysql]# cp support-files/my-default.cnf /etc/my.cnf
修改/etc/my.cnf 文件,指定datadir、basedir 路径,同时开启3306端口:
basedir = /usr/local/mysqldatadir = /data/mysqlport = 3306
7、复制mysql 启动脚本mysql.server 到/etc/init.d/mysqld
[root@localhost mysql]# cp support-files/mysql.server /etc/init.d/mysqld
8、修改启动脚本的权限为755,赋予执行权限
[root@localhost mysql]# chmod 755 /etc/init.d/mysqld
9、通过chkconfig命令将mysqld服务加入到自启动服务项中:
[root@localhost init.d]# pwd/etc/init.d[root@localhost init.d]# chkconfig --add mysqld
检查是否加入到自动启动
[root@localhost init.d]# chkconfig --list mysqldmysqld 0:off 1:off 2:on 3:on 4:on 5:on 6:off
10、启动mysql服务:
[root@localhost mysql]# service mysqld startStarting MySQL... SUCCESS!
11、进入mysql
[root@localhost mysql]#/usr/local/mysql/bin/mysqlWelcome to the MySQL monitor. Commands end with ; or \g.Your MySQL connection id is 1Server version: 5.6.26 MySQL CommunityServer (GPL)Copyright (c) 2000, 2015, Oracle and/or itsaffiliates. All rights reserved.Oracle is a registered trademark of OracleCorporation and/or itsaffiliates. Other names may be trademarksof their respectiveowners.Type 'help;' or '\h' for help. Type '\c' toclear the current input statement.mysql>
注:在/etc/profile中加入以下环境变量,可以用mysql代替/usr/local/mysql/bin/mysql启动
MYSQL_HOME=/usr/local/mysql
exportPATH=$PATH:$MYSQL_HOME/bin
设置后需要重新加载一下:
[root@localhost mysql]# source /etc/profile
再次进入mysql
[root@localhost mysql]# mysqlWelcome to the MySQL monitor.
