1、下载mysql5.5.X对应的linux 平台版本：
官网： http://dev.mysql.com/downloads/os-linux.html ，选择对应的32或者64位平台版本。
通过个人博客 下载： http://blog.s135.com/soft/linux/nginx_php/mysql/mysql-5.5.3-m3.tar.gz
wget http://blog.s135.com/soft/linux/nginx_php/mysql/mysql-5.5.3-m3.tar.gz
现假设mysql文件下载在/data0/soft目录下：
[root@local soft]# ll 总用量 23044 -rw-r--r--. 1 root root 23595610 9月 24 18:46 mysql-5.5.3-m3.tar.gz [root@local soft]# pwd /data0/soft
2、添加mysql管理的linux账户：
groupadd mysql; useradd -g mysql mysql;
3、编译安装，注意编译选项：
cd /data0/soft/mysql-5.5.3-m3/ ./configure --prefix=/usr/local/webserver/mysql/ --enable-assembler --with-extra-charsets=complex --enable-thread-safe-client --with-big-tables --with-readline --with-ssl --with-embedded-server --enable-local-infile --with-plugins=partition,innobase,myisammrg make && make install chmod +w /usr/local/webserver/mysql chown -R mysql:mysql /usr/local/webserver/mysql cd ../
prefix是数据库安装的目录，不然数据库默认安装到/usr/下各个角落。with-extra-charsets可以为complex /all /utf-8 / gbk ,with-plugins添加实际mysql运行时需要的mysql插件。
4、创建mysql数据、日志文件存放目录：
mkdir -p /data0/mysql/3306/data/ mkdir -p /data0/mysql/3306/binlog/ mkdir -p /data0/mysql/3306/relaylog/ chown -R mysql:mysql /data0/mysql/
5、创建初始化数据库数据：
/usr/local/webserver/mysql/bin/mysql_install_db --basedir=/usr/local/webserver/mysql --datadir=/data0/mysql/3306/data --user=mysql
6、创建mysql配置文件：
vi /data0/mysql/3306/my.cnf
添加如下配置文件：
[client] character-set-server = utf8 port = 3306 socket = /tmp/mysql.sock [mysqld] character-set-server = utf8 replicate-ignore-db = mysql replicate-ignore-db = test replicate-ignore-db = information_schema user = mysql port = 3306 socket = /tmp/mysql.sock basedir = /usr/local/webserver/mysql datadir = /data0/mysql/3306/data log-error = /data0/mysql/3306/mysql_error.log pid-file = /data0/mysql/3306/mysql.pid open_files_limit = 10240 back_log = 600 max_connections = 5000 max_connect_errors = 6000 table_cache = 614 external-locking = FALSE max_allowed_packet = 32M sort_buffer_size = 1M join_buffer_size = 1M thread_cache_size = 300 #thread_concurrency = 8 query_cache_size = 512M query_cache_limit = 2M query_cache_min_res_unit = 2k default-storage-engine = MyISAM thread_stack = 192K transaction_isolation = READ-COMMITTED tmp_table_size = 246M max_heap_table_size = 246M long_query_time = 3 log-slave-updates log-bin = /data0/mysql/3306/binlog/binlog binlog_cache_size = 4M binlog_format = MIXED max_binlog_cache_size = 8M max_binlog_size = 1G relay-log-index = /data0/mysql/3306/relaylog/relaylog relay-log-info-file = /data0/mysql/3306/relaylog/relaylog relay-log = /data0/mysql/3306/relaylog/relaylog expire_logs_days = 30 key_buffer_size = 256M read_buffer_size = 1M read_rnd_buffer_size = 16M bulk_insert_buffer_size = 64M myisam_sort_buffer_size = 128M myisam_max_sort_file_size = 10G myisam_repair_threads = 1 myisam_recover interactive_timeout = 120 wait_timeout = 120 skip-name-resolve #master-connect-retry = 10 slave-skip-errors = 1032,1062,126,1114,1146,1048,1396 #master-host = 192.168.1.2 #master-user = username #master-password = password #master-port = 3306 server-id = 1 innodb_additional_mem_pool_size = 16M innodb_buffer_pool_size = 512M innodb_data_file_path = ibdata1:256M:autoextend innodb_file_io_threads = 4 innodb_thread_concurrency = 8 innodb_flush_log_at_trx_commit = 2 innodb_log_buffer_size = 16M innodb_log_file_size = 128M innodb_log_files_in_group = 3 innodb_max_dirty_pages_pct = 90 innodb_lock_wait_timeout = 120 innodb_file_per_table = 0 #log-slow-queries = /data0/mysql/3306/slow.log #long_query_time = 10 vi /data0/mysql/3306/my.cnf [mysqldump] quick max_allowed_packet = 32M
也可以使用mysql的默认配置文件：
cp /usr/local/webserver/mysql/share/mysql/my-medium.cnf /data0/mysql/3306/my.cnf
修改默认配置文件：
vi /data0/mysql/3306/my.cnf
修改myqld配置节：
[mysqld] basedir = /usr/local/webserver/mysql datadir = /data0/mysql/3306/data log-error = /data0/mysql/3306/mysql_error.log pid-file = /data0/mysql/3306/mysql.pid log_slow_queries =/data0/mysql/3306/slow.log
7、制作管理脚本：
vi /data0/mysql/3306/mysql
输入如下内容：
#!/bin/sh
mysql_port=3306
mysql_username="admin"
mysql_password="12345678"
function_start_mysql()
{
printf "Starting MySQL...\n"
/bin/sh /usr/local/webserver/mysql/bin/mysqld_safe --defaults-file=/data0/mysql/${mysql_port}/my.cnf 2>&1 > /dev/null &
}
function_stop_mysql()
{
printf "Stoping MySQL...\n"
/usr/local/webserver/mysql/bin/mysqladmin -u ${mysql_username} -p${mysql_password} -S /tmp/mysql.sock shutdown
}
function_restart_mysql()
{
printf "Restarting MySQL...\n"
function_stop_mysql
sleep 5
function_start_mysql
}
function_kill_mysql()
{
kill -9 $(ps -ef | grep 'bin/mysqld_safe' | grep ${mysql_port} | awk '{printf $2}')
kill -9 $(ps -ef | grep 'libexec/mysqld' | grep ${mysql_port} | awk '{printf $2}')
}
if [ "$1" = "start" ]; then
function_start_mysql
elif [ "$1" = "stop" ]; then
function_stop_mysql
elif [ "$1" = "restart" ]; then
function_restart_mysql
elif [ "$1" = "kill" ]; then
function_kill_mysql
else
printf "Usage: /data0/mysql/${mysql_port}/mysql {start|stop|restart|kill}\n"
fi
8、启动MySQL：
/data0/mysql/3306/mysql start
9、通过命令行登录管理MySQL服务器（提示输入密码时直接回车）：
/usr/local/webserver/mysql/bin/mysql -u root -p -S /tmp/mysql.sock
10、输入以下SQL语句，创建一个具有root权限的用户（admin）和密码（12345678）：
GRANT ALL PRIVILEGES ON *.* TO 'admin'@'localhost' IDENTIFIED BY '12345678'; GRANT ALL PRIVILEGES ON *.* TO 'admin'@'127.0.0.1' IDENTIFIED BY '12345678';
11、（可选）停止MySQL：
/data0/mysql/3306/mysql stop
