linux下二进制安装mysql5.6.51版本

自行安装支持组件
mysql安装目录:/usr/local/mysql
数据库存储目录:/home/mysql/data
创建mysql用户

groupadd mysql;
useradd -g mysql -r -M -s /sbin/nologin mysql

下载并安装5.6

https://cdn.mysql.com/archives/mysql-5.6/mysql-5.6.51-linux-glibc2.12-x86_64.tar.gz
tar zxf mysql-5.6.51-linux-glibc2.12-x86_64.tar.gz
mv mysql-5.6.51-linux-glibc2.12-x86_64 mysql
mv mysql /usr/local

删除my.cnf
rm -rf /etc/my.cnf
创建/etc/my.cnf并录入以下内容

初始化

/usr/local/mysql/scripts/mysql_install_db --user=mysql --defaults-file=/etc/my.cnf --basedir=/usr/local/mysql --datadir=/home/mysql/data;
chmod 775 /usr/local/mysql/support-files/mysql.server;
/usr/local/mysql/support-files/mysql.server start;
ln -s /usr/local/mysql/bin/mysql /usr/bin/mysql;
ln -s /usr/local/mysql/bin/mysqladmin /usr/bin/mysqladmin;
ln -s /usr/local/mysql/bin/mysqldump /usr/bin/mysqldump;
ln -s /usr/local/mysql/bin/myisamchk /usr/bin/myisamchk;
ln -s /usr/local/mysql/bin/mysqld_safe /usr/bin/mysqld_safe;
rm -rf /usr/local/mysql/data/test;

加入系统启动创建/lib/systemd/system/mysql.service文件并录入以下内容

[Unit]
Description=mysql server Service
After=syslog.target network.target

[Service]
Type=forking
ExecStart=/usr/local/mysql/support-files/mysql.server start
ExecReload=/usr/local/mysql/support-files/mysql.server restart
ExecStop=/usr/local/mysql/support-files/mysql.server stop

[Install]
WantedBy=multi-user.target

创建软连并加入系统启动

ln -s /lib/systemd/system/mysql.service /etc/systemd/system/multi-user.target.wants/mysql;
systemctl daemon-reload;
systemctl enable mysql;
