OpenSUSE12.2MySQL5.6数据库安装配置_MySQL

Open SUSE12.2 MySQL5.6数据库安装配置

系统环境：Open SUSE12.2 x86_64

一、下载"SuSE Linux Enterprise Server 11 (x86, 64-bit), RPM Bundle" 或者"SuSE Linux Enterprise Server 11 (x86, 64-bit), RPM Package Client Utilities"、"SuSE Linux Enterprise Server 11 (x86, 64-bit), RPM PackageMySQL Server",地址：https://dev.mysql.com/downloads/mysql/

二、因为在新安装完的SUSE 12.2系统中，原本已有MySQL5.5.25a版本的MySQL，建议清除（本次安装是已清除原有Mysql5.5.25版本后的安装过程），不过也可以在安装过程中覆盖它。按照MySQL官网文档叙述，如果需要在本地登录，则需安同时装MySQL-server和MySQL-client：

rpm -ivh MySQL-server-5.6.13-1.sles11.x86_64.rpm

rpm -ivh MySQL-client-5.6.13-1.sles11.x86_64.rpm

三、安装完成后，你可以在目录/usr下找到my.cnf,不过这个my.cnf没什么内容，下面配置一下my.cnf,该配置仅作参考使用。

[plain] # The following options will be passed to all MySQL clients  [client]  #password   = your_password  port        = 3306  socket      = /opt/mysql/mysql.sock   # Here follows entries for some specific programs  # The MySQL server  [mysqld]  port        = 3306  socket      = /opt/mysql/mysql.sock  # Change following line if you want to store your database elsewhere  basedir=/usr  datadir = /opt/mysql  skip-external-locking  key_buffer_size = 16M  max_allowed_packet = 1M  table_open_cache = 64  sort_buffer_size = 512K  net_buffer_length = 8K  read_buffer_size = 256K  read_rnd_buffer_size = 512K  myisam_sort_buffer_size = 8M  lower_case_table_names=1  

# Don't listen on a TCP/IP port at all. This can be a security enhancement,
# if all processes that need to connect to mysqld run on the same host.
# All interaction with mysqld must be made via Unix sockets or named pipes.
# Note that using this option without enabling named pipes on Windows
# (via the "enable-named-pipe" option) will render mysqld useless!

#   #skip-networking  # Replication Master Server (default)  # binary logging is required for replication  log-bin=mysql-bin  # binary logging format - mixed recommended  binlog_format=mixed  ​# required unique id between 1 and 2^32 - 1  # defaults to 1 if master-host is not set  # but will not function as a master if omitted  server-id   = 1  # Replication Slave (comment out master section to use this)  #  # To configure this host as a replication slave, you can choose between  # two methods :  #  # 1) Use the CHANGE MASTER TO command (fully described in our manual) -  #    the syntax is:  #  #    CHANGE MASTER TO MASTER_HOST=, MASTER_PORT=,  #    MASTER_USER=, MASTER_PASSWORD= ;  #  #    where you replace , ,  by quoted strings and  #     by the master's port number (3306 by default).  #  #    Example:  #  #    CHANGE MASTER TO MASTER_HOST='125.564.12.1', MASTER_PORT=3306,  #    MASTER_USER='joe', MASTER_PASSWORD='secret';  #  # OR  #  

# 2) Set the variables below. 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-bin=mysql-bin  # Uncomment the following if you are using InnoDB tables  innodb_data_home_dir = /opt/mysql  innodb_data_file_path = ibdata1:10M:autoextend  innodb_log_group_home_dir = /opt/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 = 50  # The safe_mysqld script  [safe_mysqld]  log-error   = /var/log/mysql/mysqld.log  socket      = /opt/mysql/mysql.sock  [mysqldump]  socket      = /opt/mysql/mysql.sock  quick  max_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 = 20M  sort_buffer_size = 20M  read_buffer = 2M  write_buffer = 2M  [mysqlhotcopy]  interactive-timeout  [mysqld_multi]  mysqld     = /usr/bin/mysqld_safe  mysqladmin = /usr/bin/mysqladmin  log        = /var/log/mysqld_multi.log

四、从给出的配置文件可以看到几个信息与默认的不一样

1、basedir路径的配置

2、datadir路径的配置

3、[client] socket路径的配置

4、[mysqld] socket路径的配置

5、[safe_mysqld] socket路径的配置

6、[mysqldump] socket路径的配置

由于datadir路径配置为“/opt/mysql”，则需要把默认路径"/var/lib"下整个"mysql"文件夹复制到"/opt"下。以下是需要特别注意的地方：先查看一下"/var/lib"下"mysql"的权限和所有者；发现该文件夹的所有者为mysql。再查看"/opt"下刚才复制的"mysql"文件夹所有者，发现该所有者是root,此时如果启动mysql服务，会报错误：StartingMySQL.The server quit without updating PID file。修改"/opt"目录下的"mysql"文件夹所有者：

/opt>chown -R mysql:mysql mysql

注意：[client] socket路径的配置、[mysqld] socket路径的配置、[safe_mysqld] socket路径的配置、[mysqldump] socket路径的配置，都是配置在"/opt/mysql"下。否则会报没有找到mysql.sock错误。

启动mysql服务：service mysql start

查看mysql服务状态：service mysql status

发现一切正常，利用安装时随机生成的root密码（在`/.mysql_secret中）登陆，修改root密码或添加新用户。
