mysql8.0.15安装后，启动时服务一直是activating (start)

Question

1. 安装环境
   aliyun centos7

2. 安装

           rpm -ivh mysql-community-libs-compat-8.0.13-1.el7.x86_64.rpm
           rpm -ivh mysql-community-embedded-compat-8.0.13-1.el7.x86_64.rpm
           rpm -ivh mysql-community-devel-8.0.13-1.el7.x86_64.rpm
           rpm -ivh mysql-community-test-8.0.13-1.el7.x86_64.rpm

3. 启动mysql
   systemctl start mysqld
   然后就卡住了

   在另一个端口登录查看服务状态，一直是activating (start)，求教各位这是什么原因？

    systemctl status mysqld
   mysqld.service - MySQL Server
      Loaded: loaded (/usr/lib/systemd/system/mysqld.service; enabled)
      Active: activating (start) since Mon 2019-04-01 18:10:14 CST; 27s ago
        Docs: man:mysqld(8)
              http://dev.mysql.com/doc/refman/en/using-systemd.html
    Main PID: 1846 (mysqld)
      CGroup: /system.slice/mysqld.service
              └─1846 /usr/sbin/mysqld

   我另一个服务器是正常的

   systemctl status mysqld
   mysqld.service - MySQL Server
      Loaded: loaded (/usr/lib/systemd/system/mysqld.service; enabled; vendor preset: disabled)
      Active: active (running) since Sun 2019-03-31 11:14:20 CST; 1 day 6h ago

   Mar 31 11:14:20 VM_0_14_centos systemd[1]: Started MySQL Server.

   查看错误日志，没看到错误
   vi /var/log/mysqld.log

您好，我也遇到相同的问题，无法解决；请问您解决此问题了吗

Answer 2

楼主应该解决了吗？
我也出现了你后面报错的问题.

后面我解决了，删除了/var/run/mysqld/下的文件，然后重新启动mysql就可以了。
