    栏目:win服务器问题汇总 时间:2019-12-26 18:46

    1. 去官网下载安装包

    下载链接:点击打开链接

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

    如果你的系统是32位选择第一个,64位选择第二个

    也可以用wget 下载

    wget https://dev.mysql.com/get/Downloads/MySQL-8.0/mysql-8.0.11-linux-glibc2.12-i686.tar.gz

    解压文件

    tar -zxvf mysql-8.0.11-linux-glibc2.12-i686.tar.gz

    2 移动压缩包到usr/local目录下,并重命名文件

    mv /root/mysql-8.0.11-linux-glibc2.12-i686 /usr/local/mysql

    3.在MySQL根目录下新建一个文件夹data,用于存放数据

    mkdir data

    4.创建 mysql 用户组和 mysql 用户

    groupadd mysql
    useradd -g mysql mysql

    5.改变 mysql 目录权限

    chown -R mysql.mysql /usr/local/mysql/
     
    或者
     
    chown -R mysql .
     
    chgrp -R mysql .

    注意最后有一点

    6.初始化数据库

    创建mysql_install_db安装文件

    mkdir mysql_install_db
    chmod 777 ./mysql_install_db

    初始化

    bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data //初始化数据库

    或者

    /usr/local/mysql/bin/mysqld --initialize --user=mysql
    /usr/local/mysql/bin/mysqld --initialize --user=mysql
    /usr/local/mysql/bin/mysqld (mysqld 8.0.11) initializing of server in progress as process 5826
     [Server] A temporary password is generated for root@localhost: twi=Tlsi<0O!
    /usr/local/mysql/bin/mysqld (mysqld 8.0.11) initializing of server has completed

    记录好自己的临时密码:

    twi=Tlsi<0O!

    这里遇到了问题没有libnuma.so.1

    zsh: command not found: mysqld
    ./bin/mysqld --initialize
    ./bin/mysqld: error while loading shared libraries: libnuma.so.1: cannot open shared object file: No such file or directory

    2018-04-29 17:06:30 [WARNING] mysql_install_db is deprecated. Please consider switching to mysqld --initialize
    2018-04-29 17:06:30 [ERROR] Can't locate the language directory.

    需要安装 libnuma

    yum install libnuma
    yum -y install numactl
    yum install libaio1 libaio-dev

    安装文件

    7.mysql配置

    cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld

    修改my.cnf文件

    vim /etc/my.cnf

    [mysqld]
     basedir = /usr/local/mysql 
     datadir = /usr/local/mysql/data
     socket = /usr/local/mysql/mysql.sock
     character-set-server=utf8
     port = 3306
     sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES
     [client]
     socket = /usr/local/mysql/mysql.sock
     default-character-set=utf8

    esc保存

    :wq 退出

    8建立MySQL服务

    cp -a ./support-files/mysql.server /etc/init.d/mysqld

    cp mysql.server /etc/init.d/mysql
    chmod +x /etc/init.d/mysql
