编译安装mysql5

先yum安装 gcc ,gcc-c++, libgcc, gcc-objc

error: No curses/termcap library found

yum install ncurses-devel

编译&安装：

/usr/sbin/groupadd mysql

/usr/sbin/useradd -g mysql mysql
tar zxvf mysql-5.1.38.tar.gz
cd mysql-5.1.38/
./configure –prefix=/app/server/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=innobase
make && make install
chmod +w /app/server/mysql
chown -R mysql:mysql /app/server/mysql
cd ../

配置数据库：

①、创建MySQL数据库存放目录

②、以mysql用户帐号的身份建立数据表：

③、创建my.cnf配置文件：

输入以下内容：

[client]
default-character-set = utf8
port    = 3306
socket  = /tmp/mysql.sock

[mysql]
prompt=”(\u:zior.org:)[\d]> “
no-auto-rehash

[mysqld]
#default-character-set = utf8
user    = mysql
port    = 3306
socket  = /tmp/mysql.sock
basedir = /app/server/mysql
datadir = /app/data/mysql/3306/data
open_files_limit    = 10240
back_log = 600
max_connections = 3000
max_connect_errors = 6000
table_cache = 614
external-locking = FALSE
max_allowed_packet = 32M
sort_buffer_size = 2M
join_buffer_size = 2M
thread_cache_size = 300
thread_concurrency = 8
query_cache_size = 32M
query_cache_limit = 2M
query_cache_min_res_unit = 2k
default-storage-engine = MyISAM
default_table_type = MyISAM
thread_stack = 192K
transaction_isolation = READ-COMMITTED
tmp_table_size = 246M
max_heap_table_size = 246M
long_query_time = 1
log_long_format
log-bin = /app/data/mysql/3306/binlog
binlog_cache_size = 4M
binlog_format = MIXED
max_binlog_cache_size = 8M
max_binlog_size = 512M
expire_logs_days = 7
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_max_extra_sort_file_size = 10G
myisam_repair_threads = 1
myisam_recover

skip-name-resolve
master-connect-retry = 10
slave-skip-errors = 1032,1062,126,1114,1146,1048,1396

server-id = 1

innodb_additional_mem_pool_size = 16M
innodb_buffer_pool_size = 2048M
innodb_data_file_path = ibdata1:1024M: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
[mysqldump]
quick
max_allowed_packet = 32M

④、创建管理MySQL数据库的shell脚本：

输入以下内容（这里的用户名admin和密码12345678接下来的步骤会创建）：

 #!/bin/sh

mysql_port=3306
mysql_username="admin"
mysql_password="12345678"

function_start_mysql()
{
    printf "Starting MySQL...\n"
    /bin/sh /app/server/mysql/bin/mysqld_safe --defaults-file=/app/data/mysql/${mysql_port}/my.cnf 2>&1 > /dev/null &
}

function_stop_mysql()
{
    printf "Stoping MySQL...\n"
    /app/server/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 [ "$1" = "kill" ]; then
function_kill_mysql
else
    printf "Usage: /app/data/mysql/${mysql_port}/mysql {start|stop|restart|kill}\n"
fi

⑤、赋予shell脚本可执行权限：

⑥、启动MySQL：

⑦、通过命令行登录管理MySQL服务器（提示输入密码时直接回车）：

⑧、输入以下SQL语句，创建一个具有root权限的用户（admin）和密码（12345678）：

⑨、（可选）停止MySQL：

添加mysqld为自启动服务：

[root@localhost app]# cp /app/server/mysql/share/mysql/mysql.server /etc/init.d/mysqld
[root@localhost app]# chmod +x /etc/init.d/mysqld
[root@localhost app]# chkconfig --list |grep mysql
[root@localhost app]# chkconfig --add mysqld
[root@localhost app]# chkconfig --level 345 mysqld on
[root@localhost app]# service mysqld start

Starting MySQL.Manager of pid-file quit without updating file.[FAILED] 错误的解决：

vi /etc/init.d/mysqld

basedir=/app/server/mysql
datadir=/app/data/mysql/3306/data

修改ROOT密码：

Method 1: 在/usr/local/mysql/bin/下： ./mysqladmin -u root password ‘new_password’ 一般安装时用此方法设置。

Method 2: 在mysql状态下： mysql>UPDATE user SET password=PASSWORD(’new_password’) WHERE user=’root’; mysql>FLUSH PRIVILEGES;

Method 3: mysql>SET PASSWORD FOR root=PASSWORD(’new_password’);
