在Ubuntu上安装MySQL 5.6

我需要在我的ubuntu机器上安装mysql 5.6，因为开发的原因（最新版本包含我需要合并到一些web项目中的function）。 但是我有一些问题。 我一直在关注这个教程，它不是5.6版本的特定版本，但是我想这个教程大概是一样的： http : //www.ovaistariq.net/490/a-step-by-step-guide-to-upgrading-到MySQL-5-5 /

我不确定是否正确设置了我的/etc/my.cnf文件。 这是我有什么：

# Example MySQL config file for large systems. # # This is for a large system with memory = 512M where the system runs mainly # MySQL. # # MySQL programs look for option files in a set of # locations which depend on the deployment platform. # You can copy this option file to one of those # locations. For information about these locations, see: # http://dev.mysql.com/doc/mysql/en/option-files.html # # In this file, you can use all long options that a program supports. # If you want to know which options a program supports, run the program # with the "--help" option. # The following options will be passed to all MySQL clients [client] #password = your_password port = 3306 socket = /var/run/mysqld/mysqld.sock # Here follows entries for some specific programs # The MySQL server [mysqld] port = 3306 socket = /var/run/mysqld/mysqld.sock skip-external-locking key_buffer_size = 256M max_allowed_packet = 1M table_open_cache = 256 sort_buffer_size = 1M read_buffer_size = 1M read_rnd_buffer_size = 4M myisam_sort_buffer_size = 64M thread_cache_size = 8 query_cache_size= 16M pid_file = /usr/local/mysql/data/dev.pid basedir = /usr/local/mysql datadir = /usr/local/mysql/data tmpdir = /tmp log_error = /var/log/mysql/error.log user = mysql # Try number of CPU's*2 for thread_concurrency thread_concurrency = 8 # 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=<host>, MASTER_PORT=<port>, # MASTER_USER=<user>, MASTER_PASSWORD=<password> ; # # where you replace <host>, <user>, <password> by quoted strings and # <port> 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 = <hostname> # # The username the slave will use for authentication when connecting # to the master - required #master-user = <username> # # The password the slave will authenticate with when connecting to # the master - required #master-password = <password> # # The port the master is listening on. # optional - defaults to 3306 #master-port = <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 = /usr/local/mysql/data #innodb_data_file_path = ibdata1:10M:autoextend #innodb_log_group_home_dir = /usr/local/mysql/data # 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 = 20M # Set .._log_file_size to 25 % of buffer pool size #innodb_log_file_size = 64M #innodb_log_buffer_size = 8M #innodb_flush_log_at_trx_commit = 1 #innodb_lock_wait_timeout = 50 [mysqldump] 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 = 128M sort_buffer_size = 128M read_buffer = 2M write_buffer = 2M [mysqlhotcopy] interactive-timeout 

当我尝试跑步

 mysqld --skip-grant-tables --user=mysql 

我得到这个错误：

• 从networking到数据库服务器的连接数量非常大
• 使用反向代理的mysql / web服务器故障转移设置
• 将表从一台服务器移到另一台服务器时收到错误
• MySQL错误2026（HY000）：SSL连接错误
• MySQL init.d脚本具有不同的configuration文件

 The program 'mysqld' can be found in the following packages: * mysql-server-core-5.1 * mysql-cluster-server-5.1 Try: sudo apt-get install <selected package> 

当我尝试停止服务器，我得到这个：

 * MySQL server PID file could not be found! 

当我尝试开始时：

 Starting MySQL .. * The server quit without updating PID file (/usr/local/mysql/data/dev.pid). 

我假设我没有正确编辑my.cnf文件，但我完全失去了。 否则，我完全按照说明进行操作，并确保以前的mysql 5.1版本完全从系统中删除。

 export PATH=/path/to/mysql/bin:$PATH
