二、安装MySQL 5.1.48
1、编译安装MySQL 5.1.48
./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
2、创建MySQL用户
/usr/sbin/groupadd mysql
/usr/sbin/useradd -g mysql mysql
3、修改MySQL目录用户组
chmod +w /usr/local/webserver/mysql
chown -R mysql:mysql /usr/local/webserver/mysql
4、创建MySQL数据库存放目录
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、以mysql用户帐号的身份建立数据表
/usr/local/webserver/mysql/bin/mysql_install_db \
--basedir=/usr/local/webserver/mysql \
--datadir=/data0/mysql/3306/data --user=mysql
6、创建my.cnf配置文件
vi /data0/mysql/3306/my.cnf
输入以下内容
[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
[mysqldump]
quick
max_allowed_packet = 32M
7、创建管理MySQL数据库的shell脚本
vi /data0/mysql/3306/mysql
将下面的内容贴进去
#!/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
赋予shell脚本可执行权限
chmod +x /data0/mysql/3306/mysql
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、停止MySQL
/data0/mysql/3306/mysql stop
