Ubuntu下安装mysql5.5.14

longpan

系统：Ubuntu 10.04 LTS
Ubuntu 10.04 LTS下用apt-get install mysql-server-5.1
安装出来的是mysql版本是5.1.41-3ubuntu12.10 (Ubuntu)，版本太低我们需要的mysql event只有在mysql 5.5才支持，因此我们需要安装mysql5.5.14(mysql官方的最新稳定版本)
1.       下载

wget http://ftp.iij.ad.jp/pub/db/mysql/Downloads/MySQL-5.5/MySQL-client-5.5.14-1.linux2.6.x86_64.rpm wget http://ftp.iij.ad.jp/pub/db/mysql/Downloads/MySQL-5.5/MySQL-devel-5.5.14-1.linux2.6.x86_64.rpm wget http://ftp.iij.ad.jp/pub/db/mysql/Downloads/MySQL-5.5/MySQL-server-5.5.14-1.linux2.6.x86_64.rpm wget http://ftp.iij.ad.jp/pub/db/mysql/Downloads/MySQL-5.5/MySQL-shared-5.5.14-1.linux2.6.x86_64.rpm

2.       把rpm转换为deb包

apt-get install alien alien -d MySQL-client-5.5.14-1.linux2.6.x86_64.rpm alien -d MySQL-server-5.5.14-1.linux2.6.x86_64.rpm    alien -d MySQL-devel-5.5.14-1.linux2.6.x86_64.rpm    alien -d MySQL-shared-5.5.14-1.linux2.6.x86_64.rpm

3.       卸载原mysql

dpkg -l|grep MySQL dpkg -P libmysqlclient16 dpkg -P mysql-common dpkg -P mysql-client dpkg -P mysql-devel dpkg -P mysql-shared dpkg -P mysql-server

4.       创建帐号

groupadd mysql useradd -r -g mysql mysql

5.       安装

apt-get install libaio1 dpkg -i mysql-*.deb

6.       配置

mysql_install_db --user=mysql cat > /etc/my.cnf <<EOF # The following options will be passed to   all MySQL clients [client] #password      =   your_password port        =   3306 socket            =   /var/lib/mysql/mysql.sock default-character-set=utf8 # The MySQL server [mysqld] character-set-server=utf8 language=/usr/share/mysql/english/ port        =   3306 socket            =   /var/lib/mysql/mysql.sock skip-name-resolve #skip-locking max_connect_errors=1000 max_connections=1000 max_allowed_packet = 10M key_buffer = 128M sort_buffer_size = 64M net_buffer_length = 128K read_buffer_size = 128M read_rnd_buffer_size = 128M myisam_sort_buffer_size = 128M key_buffer_size=128M table_open_cache=128 table_cache=128 thread_cache_size=64 query_cache_size=200M query_cache_limit=200M table_definition_cache=128 myisam_data_pointer_size=7 delayed_queue_size=256 preload_buffer_size=65536 delayed_queue_size=20 preload_buffer_size=1024 innodb_read_ahead_threshold=2 innodb_buffer_pool_size=128M; innodb_additional_mem_pool=16M; thread_concurrency = 2 [mysqldump] quick max_allowed_packet = 16M [mysql] no-auto-rehash # Remove the next comment character if   you are not familiar with SQL #safe-updates [isamchk] key_buffer = 20M sort_buffer_size = 20M read_buffer = 2M write_buffer = 2M [myisamchk] key_buffer = 20M sort_buffer_size = 20M read_buffer = 2M write_buffer = 2M [mysqlhotcopy] interactive-timeout EOF

7.       修改权限

若是前面mysql_install_db --user=mysql成功的话可以跳过这步 chown -R mysql:mysql /var/lib/mysql

8.       启动

service mysql start

创建远程帐号

• grant all privileges on databaseName.* to remoteUserName@'%' identified by 'testpass';
  

9.       mysql错误解决
mysql错误日志在  /var/lib/mysql/*.log里
1)        无法找到libaio.so.1
apt-get install libaio1

2)        [ERROR] /usr/sbin/mysqld: Can't find file: './mysql/host.frm' (errno: 13)

[ERROR] Fatal error: Can't open and lock privilege tables: Can't find file: './mysql/host.frm' (errno: 13)
这个错误产生原因是mysql运行的用户是mysql没有权限访问/var/lib/mysql，可以使用
chown -R mysql:mysql /var/lib/mysql
