这篇文章主要介绍了Centos 7 安装mysql5.7.24二进制 版本的方法 及遇到问题解决办法,本文给大家介绍的非常详细，具有一定的参考借鉴价值，需要的朋友可以参考下
Mysql 二进制安装方法
下载mysql
1.解压包
tar xf mysql-5.7.24-linux-glibc2.12-x86_64.tar.gz
2.实际生产环境
mv mysql-5.7.24-linux-glibc2.12-x86_64 /usr/local/mysql5.7
a.新增Mysql用户组
groupadd mysql
b. 新增用户
opt]# useradd -r -g mysql mysql
C.给mysql 目录权限
chown -R mysql:mysql mysql5.7
3. 到初始化环境的目录
Cd /home/usr/local/mysql5.6/ mkdir data mkdir log chown -R mysql:mysql mysql5.7
4.初始化数据和指定安装目录和数据目录
./bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql5.7/ --datadir=/usr/local/mysql5.7/data/
6复制启动文件
cp mysql.server /etc/init.d/mysqld chmod +x /etc/init.d/mysqld
7.修改启动路径
vi /etc/init.d/mysqld basedir= /usr/local/mysql5.7 datadir= /usr/local/mysql5.7/data
8.增加环境变量 （最狼蚁网站SEO优化添加）l
vi /etc/profile export MYSQL_HOME=" /usr/local/mysql5.7" export PATH="$PATH:$MYSQL_HOME/bin"
9.刷新配置文件
source /etc/profile
修改配置文件
vi /etc/my.cnf [client] port=3306 [mysqld] basedir=/usr/local/mysql5.7 datadir=/usr/local/mysql5.7/data #socket=/usr/local/mysql5.7/mysql.sock socket=/tmp/mysql.sock user=mysql #skip-grant-tables # Disabling symbolic-links is recommended to prevent assorted security risks symbolic-links=0 # Settings user and group are ignored when systemd is used. # If you need to run mysqld under a different user or group, # customize your systemd unit file for mariadb according to the # instructions in http://fedoraproject.org/wiki/Systemd [mysqld_safe] log-error=/usr/local/mysql5.7/log/mysqld.log pid-file=/usr/local/mysql5.7/data/mysqld.pid # # include all files from the config directory # !includedir /etc/my.cnf.d
11.添加开启自启
chkconfig --add mysqld chkconfig mysqld on
12.启动mysqld
service mysqld start netstat -anpt
13.修改密码（密码初始化的时候有个密码）
2018-11-02T02:07:44.574468Z 1 [Note] A temporary password is generated for root@localhost: lXyB0%fi#9-S （这个就是密码） mysql> help contents ERROR 1820 (HY000): You must reset your password using ALTER USER statement before executing this statement. mysql> help contents ERROR 1820 (HY000): You must reset your password using ALTER USER statement before executing this statement. mysql> show databases; ERROR 1820 (HY000): You must reset your password using ALTER USER statement before executing this statement.
解决办法
1、 修改用户密码
mysql> alter user 'root'@'localhost' identified by 'youpassword';
或者
mysql> set password=password("youpassword");
2、刷新权限
mysql> flush privileges; mysql> help contents
