1.2 二进制安装-mysql-5.7.17
1.2.1 准备工作
系统：CentOS 6.9
二进制包： mysql-5.7.17-linux-glibc2.5-x86_64.tar.gz下载到/server/tools/中
1.2.2 解压、移动、授权
cd /server/tools/ tar xf mysql-5.7.17-linux-glibc2.5-x86_64.tar.gz mv mysql-5.7.17-linux-glibc2.5-x86_64 /application/mysql-5.7.17 ln -s /application/mysql-5.7.17 /application/mysql #创建用户 useradd -s /sbin/nologin -M mysql #建议指定UID -u 666 #授权 chown -R mysql.mysql /application/mysql-5.7.17
1.2.3 mysql配置
#初始化 /application/mysql-5.7.17/bin/mysqld --initialize --user=mysql --basedir=/application/mysql-5.7.17 --datadir=/application/mysql-5.7.17/data #记录初始密码（一定要记录此密码） #此版本与下边5.6版本不一样的地方（不允许空密码登录） #2017-12-13T11:29:09.168632Z 1 [Note] A temporary password is generated for root@localhost: +u7nkQlqw!4J #拷贝配置文件和启动文件 cp /application/mysql-5.7.17/support-files/my-default.cnf /etc/my.cnf cp /application/mysql-5.7.17/support-files/mysql.server /etc/init.d/mysqld #修改启动文件内容 sed -i ‘s#/usr/local#/application#g‘ /application/mysql-5.7.17/bin/mysqld_safe /etc/init.d/mysqld
1.2.4 启动事项
#启动 /etc/init.d/mysqld start #修改root密码 mysqladmin -uroot -p password ‘123456‘ #进入mysql （注意：-p后不能直接跟密码，否则登录失败） [root@lb01 bin]# /application/mysql/bin/mysql -uroot -p Enter password: 直接粘贴 +u7nkQlqw!4J #修改密码 [root@lb01 bin]# /application/mysql/bin/mysqladmin -uroot -p password 123456 Enter password: 直接粘贴 +u7nkQlqw!4J [root@lb01 bin]# ./mysql -uroot -p123456
