linux mysql5.5.x 安装

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
