我在最小的Centos 7盒子上新安装了Mysqld 5.6.33。
使用以下/ec/my.cnf文件成功启动：
# For advice on how to change settings please see

[mysqld]
#
# Remove leading # and set to the amount of RAM for the most important data
# cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%.
innodb_buffer_pool_size = 728M
#
# Remove leading # to turn on a very important data integrity option: logging
# changes to the binary log between backups.
log_bin
#
# Remove leading # to set options mainly useful for reporting servers.
# The server defaults are faster for transactions and fast SELECTs.
# Adjust sizes as needed, experiment to find the optimal values.
# join_buffer_size = 128M
# sort_buffer_size = 2M
# read_rnd_buffer_size = 2M
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
user=mysql
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0
# Recommended in standard MySQL setup
sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES
[mysqld_safe]
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid
但是当我添加＆＃34; safe-show-database＆＃34;线路到[mysqld]它停止启动，永远挂出状态

日志中没有任何内容。
我试过禁用SELinus但没有运气。
我还应该做些什么来解决这个问题？
