However, in case you choose this method, then# start replication for the first time (even unsuccessfully, for example# if you mistyped the password in master-password and the slave fails to# connect), the slave will create a master.info file, and any later# change in this file to the variables values below will be ignored and# overridden by the content of the master.info file, unless you shutdown# the slave server, delete master.info and restart the slaver server.# For that reason, you may want to leave the lines below untouched# (commented) and instead use CHANGE MASTER TO (see above)## required unique id between 2 and 2^32 - 1# (and different from the master)# defaults to 2 if master-host is set# but will not function as a slave if omitted#server-id 2## The replication master for this slave - required#master-host ## The username the slave will use for authentication when connecting# to the master - required#master-user ## The password the slave will authenticate with when connecting to# the master - required#master-password ## The port the master is listening on.# optional - defaults to 3306#master-port ## binary logging - not required for slaves, but recommended#log-binmysql-bin# Uncomment the following if you are using InnoDB tables#innodb_data_home_dir /var/lib/mysql#innodb_data_file_path ibdata1:10M:autoextend#innodb_log_group_home_dir /var/lib/mysql# You can set .._buffer_pool_size up to 50 - 80 %# of RAM but beware of setting memory usage too high#innodb_buffer_pool_size 16M#innodb_additional_mem_pool_size 2M# Set .._log_file_size to 25 % of buffer pool size#innodb_log_file_size 5M#innodb_log_buffer_size 8M#innodb_flush_log_at_trx_commit 1#innodb_lock_wait_timeout 50slow_query_log 1long_query_time 10log-queries-not-using-indexeslog-error/data/mysql/mysql.errexpire-logs-days 10[mysqldump]quickmax_allowed_packet 16M[mysql]no-auto-rehash# Remove the next comment character if you are not familiar with SQL#safe-updates[myisamchk]key_buffer_size 20Msort_buffer_size 20Mread_buffer 2Mwrite_buffer 2M[mysqlhotcopy]interactive-timeout六、初始化数据库注5.7版本的rpm包安装之后默认不再创建数据库mysql服务也不会自动启动。但是它还是自动增加了系统用户mysql。kingtry:~ # mkdir -p /data/mysql/data #创建存放数据文件目录kingtry:~ # chown -R mysql /data/mysqlkingtry:~ # mysqld --initialize --datadir/data/mysql/data/ --usermysql #初始化初始化成功之后会将root的默认密码写入文件/data/mysql/mysql.err 中如下A temporary password is generated for [email protected]: _tVUgaq%P25Q #这就是root的默认密码七、启动mysql服务即可kingtry:~ # service mysql start doneStarting MySQL. donekingtry:~ #检查MySQL服务是否已经启动kingtry:~ # netstat -nat | grep 3306八、安装后配置之root密码修改root初始密码自动生成默认存放在/data/mysql/mysql.err 中。修改root密码的方式有以下两种随便哪个都行1、命令方式kingtry:~ # mysqladmin -u root -p password root123Enter password:2、修改库表数据方式先登陆mysql服务器mysql use mysqlmysql update user set passwordpassword(root123) where userroot;mysql commit;九、防火墙允许3306端口kingtry:~ # vi /etc/sysconfig/SuSEfirewall2在FW_SERVICES_EXT_TCP增加3306端口如果存在其他端口则空格隔开如FW_SERVICES_EXT_TCP21 22 3306重启防火墙# rcSuSEfirewall2 restart十、设置远程访问先登陆mysql服务器授权root用户可以远程登陆mysql grant all PRIVILEGES on *.* to [email protected]% identified by root123;Query OK, 0 rows affected (0.00 sec)mysql flush privileges;Query OK, 0 rows affected (0.00 sec)mysql注生产环境最好只允许root在特定IP的机器上才能远程访问。原文http://blog.51cto.com/10759919/2150853
