本篇文章給大家分享的是有關 CentOS 中怎樣安裝 MySQL，丸趣 TV 小編覺得挺實用的，因此分享給大家學習，希望大家閱讀完這篇文章后可以有所收獲，話不多說，跟著丸趣 TV 小編一起來看看吧。
1. 軟件獲得
可以從官方網站獲得穩定版本 mysql5.1.58。選擇 souce code, 壓縮包安裝文件。
若主機直接連接公網，可在主機上直接使用如下方式獲得軟件包：
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. 安裝方法
1） 解壓軟件包
tar xvf mysql-5.1.58.tar.gz
2） 配置 mysql 用戶
useradd ndash;d /home/mysql mysql
編輯 mysql 用戶的.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，編譯，編譯安裝
./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） 創建 MySQL
創建數據庫之前，先編輯 my.cnf 文件。my.cnf 文件放在 MySQL 的安裝目錄下面（/home/）。my.cnf 文件內容如下：
[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
創建相關目錄：
mkdir -p /home/mysql/data/
mkdir -p /home/mysql/log/
創建數據庫命令如下：
/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 為系統 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 啟動
service mysql start
7） 修改 MySQL root 密碼
/home/mysql/bin/mysqladmin -u root password mysql
修改 mysql root 的密碼為 mysql
8） MySQL 關閉
service mysql stop
