Centos6.5安装mysql-5.7.23

Posted 2020-12-30 pig-driving-spacecraft

1.卸载系统自带mysq(没有忽略此步骤)

　　[[email protected] ~]$ rpm -qa|grep mysql

　　mysql-community-common-5.7.19-1.el6.x86_64

　　rpm -e --nodeps mysql-community-common-5.7.19-1.el6.x86_64

2.下载解压安装包

　　[[email protected] apps]$ wget https://cdn.mysql.com//Downloads/MySQL-5.7/mysql-5.7.23-linux-glibc2.12-x86_64.tar.gz

　　[[email protected] apps]$ tar -zxvf mysql-5.7.23-linux-glibc2.12-x86_64

3.修改配置文件

　　[[email protected] apps]$ cd mysql-5.7.23-linux-glibc2.12-x86_64/support-files/

      [[email protected] support-files]$ vi mysql.server

　　

4.安装

　　[[email protected] support-files]$ sudo cp mysql.server /etc/init.d/mysqld　　

　　[[email protected] support-files]$ cd ../bin/
　　[[email protected] bin]$ ./mysqld --user=mysql --basedir=/home/admin/apps/mysql-5.7.23-linux-glibc2.12-x86_64 --datadir=/home/admin/data/mysql/data --initialize　　

　　此步骤有可能报错：/bin/mysqld: error while loading shared libraries: libaio.so.1: cannot open shared object file:

　　解决方案：sudo yum remove libnuma.so.1

　　　　　　　sudo  yum -y install numactl.x86_64

　　　　　　　yum install -y libaio 

5.启动mysql服务

　　[[email protected] bin]$ service mysqld start

6.登录修改root密码

　　

7.卸载
