centos 7 安装二进制mysql 详细步骤

1 下载地址：https://cdn.mysql.com//Downloads/MySQL-5.7/mysql-5.7.24-linux-glibc2.12-x86_64.tar.gz 复制这个链接在迅雷上下载比较快。

2 上传到centos服务器：scp mysql-5.7.24-linux-glibc2.12-x86_64.tar.gz root@39.105.221.232:/usr/local

3 解压到 /usr/loacl 目录

4 重命名 mv  mysql-5.7.24-linux-glibc2.12-x86_64 mysql

5 创建 mysql用户和组

　　groupadd mysql

　　useradd mysql -g mysql

6 进入mysql目录 创建data文件夹  mkdir data

7 修改mysql目录的用户权限 chown -R mysql.mysql 

8 进入mysql/bin 目录 执行 ./mysqld --initialize --user=mysql --basedir=/usr/local/mysql/ --datadir=/usr/local/mysql/data/ 初始化mysql

如果报 ./mysqld: error while loading shared libraries: libaio.so.1: cannot open shared object file: No such file or directory 这个错误，说明没有安装libaio 那么应该去安装libaio

　　rpm -qa|grep libaio 检查是否安装若未安装则执行：yum install  libaio-devel.x86_64 安装。安装成功后进入mysql/bin目录再次执行

　　./mysqld --initialize --user=mysql --basedir=/usr/local/mysql/ --datadir=/usr/local/mysql/data/

　　出现以下内容，说明初始化成功。@loaclhost 后面是初始化的登陆密码。

--24T15::.283846Z  [Warning] TIMESTAMP with implicit DEFAULT value is deprecated. Please use --explicit_defaults_for_timestamp server option (see documentation for more details).

9 添加mysql启动到本地服务 cp /usr/local/mysql/mysql.server /etc/init.d/mysql.server

10 启动mysql服务：service mysql.server start

看到

Starting MySQL.Logging to '/usr/local/mysql/data/iZ2ze2h6biv9bg5169c9gtZ.err'.
[ OK ]

就表示启动成功了。

11 设置环境变量，并使环境变量生效

export PATH=$PATH:/usr/local/mysql/bin

12 启动mysql ，密码是初始化使生成的默认密码。到此，完全完成myql的安装。

　　mysql -uroot -p
