一. 安装环境准备

  1. 系统信息
    CentOS release 6.5 (Final)
    2.6.32-431.el6.x86_64
  2. 目录创建
    程序目录:/usr/local/mysql_5.7.22/
    数据目录:/var/lib/mysql_5.7.22/data/
    命令:
    mkdir /var/lib/mysql_5.7.22/{data,logs,tmp} -p
    chown -R mysql:mysql  /var/lib/mysql_5.7.22
  3. 安装依赖
    yum -y install numactl.x86_64
    不然初始化报错:
    error while loading shared libraries: libnuma.so.1: cannot open shared object file: No such file or directory
  4. 准备my.cnf配置文件
    参数详细解释参考:https://blog.csdn.net/gzt19881123/article/details/52594783

    tmpdir = /var/lib/mysql_5.7.22/tmp/
    socket = /var/lib/mysql_5.7.22/tmp/mysql.sock

    log-error=/var/lib/mysql_5.7.22/logs/mysqld.log
    pid-file=/var/lib/mysql_5.7.22/tmp/mysqld.pid

    二. 安装初始化

  5. 下载解压:
    https://cdn.mysql.com/archives/mysql-5.7/mysql-5.7.22-linux-glibc2.12-x86_64.tar.gz
    tar -xf mysql-5.7.22-linux-glibc2.12-x86_64.tar.gz -C /usr/local/
    mv mysql-5.7.22-linux-glibc2.12-x86_64/  mysql_5.7.22
  6. 初始化:
    /usr/local/mysql_5.7.22/bin/mysqld --defaults-file=/usr/local/mysql_5.7.22/my.cnf --basedir=/usr/local/mysql_5.7.22/ --datadir=/var/lib/mysql_5.7.22/data/ --initialize
    查看日志less /var/lib/mysql_5.7.22/logs/error.log,看是否有报错
  7. 启动mysql
    /usr/local/mysql_5.7.22/bin/mysqld_safe --defaults-file=/usr/local/mysql_5.7.22/my.cnf &
    这个时候会报错显示没有/var/lib/mysql_5.7.22/logs/mysqld.log这个日志文件,手动创建,重新启动就不会报错
    touch /var/lib/mysql_5.7.22/logs/mysqld.log
    启动完成后,查看日志文件是否有报错
    ps waux |grep mysql 查看进程是否启动
  8. 登录mysql
    grep password /var/lib/mysql_5.7.22/logs/error.log 查看原始密码
    类似这样[email protected]: yn.X?gQ!d2?3
    /usr/local/mysql_5.7.22/bin/mysql -uroot -p‘yn.X?gQ!d2?3‘ -S /var/lib/mysql_5.7.22/tmp/mysql.sock
  9. 登录mysql 后修改密码
    set password=password(‘123456’);
