CentOS中怎样安装MySQL

本篇文章给大家分享的是有关CentOS中怎样安装MySQL，小编觉得挺实用的，因此分享给大家学习，希望大家阅读完这篇文章后可以有所收获，话不多说，跟着小编一起来看看吧。

1.    软件获得

可以从官方网站获得稳定版本mysql5.1.58。选择souce code,压缩包安装文件。

若主机直接连接公网，可在主机上直接使用如下方式获得软件包：

wget http://dev.mysql.com/get/Downloads/MySQL-5.1/mysql-5.1.58.tar.gz/from/http://ftp.jaist.ac.jp/pub/mysql/

2.    安装方法

1）            解压软件包

tar xvf mysql-5.1.58.tar.gz

2）            配置mysql用户

useradd –d /home/mysql mysql

编辑mysql用户的.bash_profile

# .bash_profile

# Get the aliases and functions

if [ -f ~/.bashrc ]; then

        . ~/.bashrc

fi

# User specific environment and startup programs

PATH=$PATH:$HOME/bin:/sbin

export PATH

export PS1="[\u@\h \w ]\$"

3）            配置，编译，编译安装

./configure --prefix=/home/mysql/ \

--with-unix-socket-path=/home/mysql/mysql.sock \

--with-big-tables \

--with-charset=utf8 \

--with-collation=utf8_general_ci \

--with-extra-charsets=gbk,gb2312,utf8 \

--with-client-ldflags=-all-static \

--with-mysqld-ldflags=-all-static \

--with-plugins=partition,innobase,myisammrg \

--with-pthread \

--with-readline \

--without-debug \

--without-isam \

--enable-assembler \

--enable-local-infile \

--enable-thread-safe-client

make

make install

4）            创建MySQL

创建数据库之前，先编辑my.cnf文件。my.cnf文件放在MySQL的安装目录下面（/home/）。my.cnf 文件内容如下：

[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 = /home/mysql

datadir = /home/mysql/data

log-error = /home/mysql/log/error.log

pid-file = /home/mysql/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 = /home/mysql/log/binlog

binlog_cache_size = 4M

binlog_format = MIXED

max_binlog_cache_size = 8M

max_binlog_size = 1G

relay-log-index = /home/mysql/log/relaylog

relay-log-info-file = /home/mysql/log/relaylog

relay-log = /home/mysql/log/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 = /home/mysql/log/slow.log

#long_query_time = 10

[mysqldump]

quick

max_allowed_packet = 32M

创建相关目录：

mkdir -p /home/mysql/data/

mkdir -p /home/mysql/log/

创建数据库命令如下：

/home/mysql/bin/mysql_install_db \       

--defaults-file=/home/mysql/my.cnf \        

--basedir=/home/mysql \

--datadir=/home/mysql/data \            

--user=mysql

5）            配置MySQL为系统service

cp /home/mysql/my.cnf /etc/

cp /usr/local/web/mysql/share/mysql/mysql.server /etc/rc.d/init.d/mysql

chmod +x /etc/rc.d/init.d/mysql

chkconfig --add mysql

6）            MySQL启动

service mysql start

7）            修改MySQL root 密码

/home/mysql/bin/mysqladmin -u root password 'mysql'

修改mysql root的密码为mysql

8）            MySQL关闭

service mysql stop
