CentOS安装多版本MySQL

前言

卓音工作室的服务器中,已经安装了MySQL5.7。但是,confluence和jira不支持MySQL5.7,为了安装这两款软件,必须安装MySQL5.6或更低的版本。

安装详解

安装开发包

1
yum -y install wget gcc-c++ ncurses ncurses-devel cmake make perl bison openssl openssl-devel gcc* libxml2 libxml2-devel curl-devel libjpeg* libpng* freetype* --setopt=protected_multilib=false

下载MySQL

搜狐镜像:http://mirrors.sohu.com/mysql/MySQL-5.6/
选择下载:mysql-5.6.34.tar.gz

安装前准备

1、创建一个Mysql用户,useradd mysql

2、新建mysql下data和log子目录

1
2
mkdir -p /usr/local/mysql{3306,3307}/data            
mkdir -p /usr/local/mysql{3306,3307}/log

3、修改目录的所属者以及所属组权限

1

4
chown -R mysql:mysql /usr/local/mysql{3306,3307}/data/  
chown -R mysql:mysql /usr/local/mysql{3306,3307}/log/
chmod 750 /usr/local/mysql{3306,3307}/data
chmod 750 /usr/local/mysql{3306,3307}/log

4、创建mysql相关目录并配置权限

mkdir -p /usr/local/mysql{3306,3307}/etc  
chown -R mysql.mysql /usr/local/mysql{3306,3307}/etc
mkdir -p /var/run/mysqld{3306,3307}
chown -R mysql.mysql /var/run/mysqld{3306,3307}
mkdir -p /var/lib/mysqld{3306,3307}
chown -R mysql.mysql /var/lib/mysqld{3306,3307}

5、创建mysql.sock文件

1
touch /tmp/mysql{3306,3307}.sock

解压MySQL

1、使用xftp上传mysql-5.6.34.tar.gz到CentOS服务器。
2、tar -zxvf mysql-5.6.34.tar.gz,解压mysql。

编译安装MySQL

1、cd mysql-5.6.34,进入mysql源文件目录。
2、配置编译。

-DSYSCONFDIR=/usr/local/mysql3307/etc \
-DWITH_MYISAM_STORAGE_ENGINE=1 \

-DEXTRA_CHARSETS=all \
-DDEFAULT_CHARSET=utf8 \
-DDEFAULT_COLLATION=utf8_general_ci \
-DMYSQL_USER=mysql \
-DWITH_DEBUG=0 \
-DWITH_SSL=system

3、编译安装

1
2
make
make install

这一步时间较长,请耐心等待。

配置MySQL

1、拷贝模板,作为配置文件。

1
cp /usr/local/mysql3307/support-files/my-default.cnf /usr/local/mysql3307/etc/my.cnf

2、设置开机启动。

1
cp /usr/local/mysql3307/support-files/mysql.server /etc/init.d/mysqld3307

3、修改my.cnf

# For advice on how to change settings please see

# *** DO NOT EDIT THIS FILE. It's a template which will be copied to the

# *** upgrade to a newer version of MySQL.

[mysqld]

# Remove leading # and set to the amount of RAM for the most important data
# cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%.
# innodb_buffer_pool_size = 128M

# Remove leading # to turn on a very important data integrity option: logging
# changes to the binary log between backups.
# log_bin

# These are commonly set, remove the # and set as required.
basedir = /usr/local/mysql3307
datadir = /usr/local/mysql3307/data
port = 3307
# server_id = .....
socket = /tmp/mysql3307.sock

# Remove leading # to set options mainly useful for reporting servers.

4、初始化mysql数据库。

1
/usr/local/mysql3307/scripts/mysql_install_db --basedir=/usr/local/mysql3307 --datadir=/usr/local/mysql3307/data --user=mysql

启动MySQL

1、启动mysql
service mysqld3307 start

2、设置超级管理员密码
/usr/local/mysql3307/bin/mysqladmin -u root password voidking -S /tmp/mysql3307.sock

3、登录mysql
mysql -u root -p -S /tmp/mysql3307.sock,然后输入密码voidking,成功登录mysql5.6。

至此,多版本mysql安装配置成功!

远程连接

1、关闭防火墙
systemctl stop firewalld.service

2、登录mysql控制台:
mysql> grant all privileges on *.* to 'root'@'%' identified by 'voidking' with grant option;

3、远程连接测试
方案一:使用navicat等图形化工具。
方案二:使用mysql命令,比如mysql -h 192.168.56.101 -P 3307 -u root -pvoidking
