注：kingtry是我的主机名
一、环境准备
操作系统：SuSE版本11sp3，64位
kingtry:~ # uname -a Linux kingtry 3.0.76-0.11-default #1 SMP Fri Jun 14 08:21:43 UTC 2013 (ccab990) x86_64 x86_64 x86_64 GNU/Linux kingtry:~ # cat /etc/SuSE-release SUSE Linux Enterprise Server 11 (x86_64) VERSION = 11 PATCHLEVEL = 3
二、检测是否安装过MySQL
kingtry:~ # rpm -qa | grep -i mysql libmysqlclient_r15-5.0.96-0.6.1 libqt4-sql-mysql-4.6.3-5.25.4 MySQL-client-community-5.1.73-1.sles11 MySQL-server-community-5.1.73-1.sles11
注意输出的MySQL-*，表示已经安装过。lib开头的可以忽略。
输入以下命令删除：
kingtry:~ #rpm -e MySQL-client-community-5.1.73-1.sles11 kingtry:~ #rpm -e MySQL-server-community-5.1.73-1.sles11
三、软件准备
MySQL-server-5.6.40-1.sles11.x86_64.rpm MySQL-client-5.6.40-1.sles11.x86_64.rpm
四、安装过程
kingtry:~ # rpm -ivh MySQL-* warning: MySQL-client-5.6.40-1.sles11.x86_64.rpm: Header V3 DSA signature: NOKEY, key ID 5072e1f5 Preparing... ########################################### [100%] 1:MySQL-server ########################################### [ 50%] warning: user mysql does not exist - using root warning: group mysql does not exist - using root warning: user mysql does not exist - using root warning: group mysql does not exist - using root insserv: Service network is missed in the runlevels 4 to use service mysql mysql 0:off 1:off 2:on 3:on 4:on 5:on 6:off [......此处省略若干行......] A random root password has been set. You will find it in '/root/.mysql_secret'. 2:MySQL-client ########################################### [100%] kingtry:~ #
注意：上面输出内容中有个文件 /root/.mysql_secret，含有mysql的root用户的默认密码
如果想查询rpm包详细的安装文件列表及每个文件的实际存储路径，可通过命令rpm -ql来查询，如：
kingtry:~ # rpm -ql MySQL-server-5.6.40-1.sles11 /etc/init.d/mysql /etc/logrotate.d/mysql /etc/my.cnf /etc/my.cnf.d /usr/bin/innochecksum /usr/bin/my_print_defaults /usr/bin/myisam_ftdump /usr/bin/myisamchk /usr/bin/myisamlog /usr/bin/myisampack /usr/bin/mysql_convert_table_format /usr/bin/mysql_fix_extensions /usr/bin/mysql_install_db /usr/bin/mysql_plugin /usr/bin/mysql_secure_installation ......
五、安装后配置之迁移数据库目录
rpm这种安装方式默认将数据文件安装到/var/lib/mysql这个目录下面，通常都需要迁移到其他目录下，如迁移到/data目录下
kingtry:~ # mkdir -p /data/mysql/{data,tmp}
kingtry:~ # mv /var/lib/mysql/* /data/mysql/data
kingtry:~ # touch /data/mysql/mysql.err #此文件需要手工创建，当前版本问题
kingtry:~ # chown -R mysql /data/mysql1，复制my.cnf模板文件
模板文件在/usr/share/mysql/my-default.cnf目录下，
kingtry:~ # cp /usr/share/mysql/my-default.cnf /etc/my.cnf
修改相关参数，主要是socket, datadir， 如下：
# For advice on how to change settings please see # http://dev.mysql.com/doc/refman/5.6/en/server-configuration-defaults.html [client] #password = your_password port = 3306 socket = /data/mysql/mysql.sock default-character-set=utf8 # Here follows entries for some specific programs # The MySQL server [mysqld] port = 3306 datadir = /data/mysql/data tmpdir = /data/mysql/tmp socket = /data/mysql/mysql.sock character-set-server = utf8 collation-server = utf8_general_ci pid-file = /data/mysql/mysql.pid user = mysql explicit_defaults_for_timestamp lower_case_table_names = 1 max_connections = 1000 back_log = 1024 open_files_limit = 10240 table_open_cache = 5120 #bind-address = 127.0.0.1 #skip-name-resolve skip-external-locking local-infile = 1 key_buffer_size = 32M 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 # 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 = /data/mysql/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 = /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 = 256M #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 innodb_buffer_pool_instances = 2 innodb_read_io_threads = 8 innodb_write_io_threads = 8 innodb_purge_threads = 1 slow_query_log = 1 long_query_time = 10 log-queries-not-using-indexes log-error = /data/mysql/mysql.err expire-logs-days = 10 [mysqldump] quick max_allowed_packet = 512M net_buffer_length = 16384 [mysql] 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
六、启动mysql服务即可
kingtry:~ # service mysql start done Starting MySQL. done kingtry:~ #
检查MySQL服务是否已经启动：
kingtry:~ # netstat -nat | grep 3306
七、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/root/.mysql_secret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 'root123' Enter password:
2、修改库表数据方式
先登陆mysql服务器
mysql> use mysql
mysql> update user set password=password('root123') where user='root';
mysql> commit;八、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_TCP="21 22 3306"
重启防火墙：
# rcSuSEfirewall2 restart
九、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 root@'%' 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。
关于RPM安装方式说明：
显面易见的是简单；
但缺点也比较突出：不灵活，通过RPM管理的单个系统中只能安装一套MySQL
