Centos 7 安装mysql5.7.24二进制 版本的方法及解决办法

Mysql 二进制安装方法

下载mysql

https://dev.mysql.com/downloads/mysql/

1.解压包

tar xf mysql-5.7.24-linux-glibc2.12-x86_64.tar.gz

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 datamkdir logchown -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/mysqldchmod +x /etc/init.d/mysqld

7.修改启动路径

 vi /etc/init.d/mysqldbasedir= /usr/local/mysql5.7datadir= /usr/local/mysql5.7/data

8.增加环境变量 （最下面添加）l

 vi /etc/profileexport 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/mysql5.7datadir=/usr/local/mysql5.7/data#socket=/usr/local/mysql5.7/mysql.socksocket=/tmp/mysql.sockuser=mysql#skip-grant-tables# Disabling symbolic-links is recommended to prevent assorted security riskssymbolic-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.logpid-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）
