Linux下Mysql5.7开启binlog步骤及注意事项

主要步骤同上一篇windows的配置
Linux 下的配置文件为 my.cnf,windows下为my.ini
配置文件在目录 /etc/my.cnf 配置

log_bin=mysql_bin
binlog-format=Row
server-id=1
系统变量binlog_format 指定二进制日志的类型。分别有STATEMENT、ROW、MIXED三种值。MySQL 5.7.6之前默认为STATEMENT模式。MySQL 5.7.7之后默认为ROW模式。这个参数主要影响主从复制。
复制的模式有下面几种:基于SQL语句的复制(statement-based replication, SBR)，基于行的复制(row-based replication, RBR)，混合模式复制(mixed-based replication, MBR)。

# 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 = 128M
#
# Remove leading # to turn on a very important data integrity option: logging
# changes to the binary log between backups.
log_bin=mysql_bin
binlog-format=Row
server-id=1
#
# 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

# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0

log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid


collation-server = utf8_unicode_ci
init-connect='SET NAMES utf8'
character-set-server = utf8
sql_mode=NO_ZERO_IN_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION

[client]
default-character-set=utf8
[mysql]
default-character-set=utf8

如果没有对log-bin指定log文件，默认在 /var/lib/mysql目录下以mysqld-bin.00000X等作为名称。而 mysqld-bin.index则记录了所有的log的文件名称
使用时则使用mysqlbinlog /var/lib/mysql|grep "*****"等来追踪database的操作。

修改默认mysql的编码

mysql> SHOW VARIABLES LIKE 'character%';
+--------------------------+----------------------------+
| Variable_name            | Value                      |
+--------------------------+----------------------------+
| character_set_client     | utf8                       |
| character_set_connection | utf8                       |
| character_set_database   | latin1                     |
| character_set_filesystem | binary                     |
| character_set_results    | utf8                       |
| character_set_server     | latin1                     |
| character_set_system     | utf8                       |
| character_sets_dir       | /usr/share/mysql/charsets/ |
+--------------------------+----------------------------+

然后vim /etc/my.cnf
在追后面添加

collation-server = utf8_unicode_ci
init-connect='SET NAMES utf8'
character-set-server = utf8
sql_mode=NO_ZERO_IN_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION

[client]
default-character-set=utf8
[mysql]
default-character-set=utf8

然后重启mysql
service mysqld restart

再进入mysql确认(SHOW VARIABLES LIKE 'character%';)
