MySQL加入log_bin报错

MySQL中二进制日志功能默认是关闭的，查看各种开启方式后，确定在配置文件中加入如下配置来开启该功能：

[root@bogon /]# more /etc/my.cnf
[mysqld]
datadir=/var/lib/mysql
#socket=/var/lib/mysql/mysql.sock
socket=/var/run/mysql/mysql.sock
# Disabling symbolic-links is recommended to prevent assorted security risks
ft_min_word_len = 1
symbolic-links=0
max_connections=1000
max_allowed_packet=100M
# Settings user and group are ignored when systemd is used.
# If you need to run mysqld under a different user or group,
# customize your systemd unit file for mariadb according to the
# instructions in http://fedoraproject.org/wiki/Systemd

# Remove leading # to turn on a very important data integrity option: logging
# # changes to the binary log between backups.
log_bin=mysql-bin

[mysqld_safe]
log-error=/var/log/mariadb/mariadb.log
pid-file=/var/run/mariadb/mariadb.pid

#
# include all files from the config directory
#
!includedir /etc/my.cnf.d

然后启动MySQL报错

解决方法：

在设置 log-bin 的时候同时需要设置 server-id 变量，即在配置文件中添加：

# Remove leading # to turn on a very important data integrity option: logging
# # changes to the binary log between backups.
log_bin=mysql-bin
server-id=1 

启动成功：
