MySQL 安裝配置
MySQL 是最受歡迎的關聯式資料庫管理系統,由瑞典MySQL AB公司開發,目前屬於Oracle公司。
MySQL所使用的SQL語言是用來存取資料庫的最常用標準化語言。
MySQL由於體積小、速度快、整體擁有成本低,尤其是開放原始碼這一特點,一般中小型網站的開發都選擇MySQL作為網站資料庫。
MySQL 安裝
本教學的系統平台:CentOS release 6.6 (Final) 64位元。
一、安裝編譯工具及函式庫檔案
yum -y install gcc gcc-c++ make autoconf libtool-ltdl-devel gd-devel freetype-devel libxml2-devel libjpeg-devel libpng-devel openssl-devel curl-devel bison patch unzip libmcrypt-devel libmhash-devel ncurses-devel sudo bzip2 flex libaio-devel
二、 安裝cmake 編譯器
cmake 版本:cmake-3.1.1。
1、下載網址:http://www.cmake.org/files/v3.1/cmake-3.1.1.tar.gz
[root@w3cschool,cc src]# wget http://www.cmake.org/files/v3.1/cmake-3.1.1.tar.gz
2、解壓縮安裝套件
[root@w3cschool,cc src]# tar zxvf cmake-3.1.1.tar.gz
3、進入安裝套件目錄
[root@w3cschool,cc src]# cd cmake-3.1.1
4、編譯安裝
[root@w3cschool,cc cmake-3.1.1]# ./bootstrap [root@w3cschool,cc cmake-3.1.1]# make && make install
三、安裝MySQL
##MySQL版本:mysql- 5.6.15。 1、下載網址: http://dev.mysql.com/get/Downloads/MySQL-5.6/mysql-5.6.15.tar.gz[root@w3cschool,cc src]# wget http://dev.mysql.com/get/Downloads/MySQL-5.6/mysql-5.6.15.tar.gz2、解壓縮安裝包
[root@w3cschool,cc src]# tar zxvf mysql-5.6.15.tar.gz3、進入安裝包目錄
[root@w3cschool,cc src]# cd mysql-5.6.154、編譯安裝
[root@w3cschool,cc mysql-5.6.15]# cmake -DCMAKE_INSTALL_PREFIX=/usr/local/webserver/mysql/ -DMYSQL_UNIX_ADDR=/tmp/mysql.sock -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DWITH_EXTRA_CHARSETS=all -DWITH_MYISAM_STORAGE_ENGINE=1 -DWITH_INNOBASE_STORAGE_ENGINE=1 -DWITH_MEMORY_STORAGE_ENGINE=1 -DWITH_READLINE=1 -DWITH_INNODB_MEMCACHED=1 -DWITH_DEBUG=OFF -DWITH_ZLIB=bundled -DENABLED_LOCAL_INFILE=1 -DENABLED_PROFILING=ON -DMYSQL_MAINTAINER_MODE=OFF -DMYSQL_DATADIR=/usr/local/webserver/mysql/data -DMYSQL_TCP_PORT=3306 [root@w3cschool,cc mysql-5.6.15]# make && make install5、查看mysql版本:
[root@w3cschool,cc mysql-5.6.15]# /usr/local/webserver/mysql/bin/mysql --version到此,mysql安裝完成。
MySQL 設定1、建立mysql運行使用的使用者mysql:
[root@bogon conf]# /usr/sbin/groupadd mysql [root@bogon conf]# /usr/sbin/useradd -g mysql mysql2、建立binlog和函式庫的儲存路徑並賦予mysql使用者權限
[root@w3cschool,cc mysql]# mkdir -p /usr/local/webserver/mysql/binlog /www/data_mysql [root@w3cschool,cc mysql]# chown mysql.mysql /usr/local/webserver/mysql/binlog/ /www/data_mysql/2、建立my.cnf設定檔將/etc/my.cnf替換為下面內容
[root@w3cschool,cc mysql]# cat /etc/my.cnf [client] port = 3306 socket = /tmp/mysql.sock [mysqld] 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 = /www/data_mysql log-error = /usr/local/webserver/mysql/mysql_error.log pid-file = /usr/local/webserver/mysql/mysql.pid open_files_limit = 65535 back_log = 600 max_connections = 5000 max_connect_errors = 1000 table_open_cache = 1024 external-locking = FALSE max_allowed_packet = 32M sort_buffer_size = 1M join_buffer_size = 1M thread_cache_size = 600 #thread_concurrency = 8 query_cache_size = 128M query_cache_limit = 2M query_cache_min_res_unit = 2k default-storage-engine = MyISAM default-tmp-storage-engine=MYISAM thread_stack = 192K transaction_isolation = READ-COMMITTED tmp_table_size = 128M max_heap_table_size = 128M log-slave-updates log-bin = /usr/local/webserver/mysql/binlog/binlog binlog-do-db=oa_fb binlog-ignore-db=mysql binlog_cache_size = 4M binlog_format = MIXED max_binlog_cache_size = 8M max_binlog_size = 1G relay-log-index = /usr/local/webserver/mysql/relaylog/relaylog relay-log-info-file = /usr/local/webserver/mysql/relaylog/relaylog relay-log = /usr/local/webserver/mysql/relaylog/relaylog expire_logs_days = 10 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 loose-innodb-trx=0 loose-innodb-locks=0 loose-innodb-lock-waits=0 loose-innodb-cmp=0 loose-innodb-cmp-per-index=0 loose-innodb-cmp-per-index-reset=0 loose-innodb-cmp-reset=0 loose-innodb-cmpmem=0 loose-innodb-cmpmem-reset=0 loose-innodb-buffer-page=0 loose-innodb-buffer-page-lru=0 loose-innodb-buffer-pool-stats=0 loose-innodb-metrics=0 loose-innodb-ft-default-stopword=0 loose-innodb-ft-inserted=0 loose-innodb-ft-deleted=0 loose-innodb-ft-being-deleted=0 loose-innodb-ft-config=0 loose-innodb-ft-index-cache=0 loose-innodb-ft-index-table=0 loose-innodb-sys-tables=0 loose-innodb-sys-tablestats=0 loose-innodb-sys-indexes=0 loose-innodb-sys-columns=0 loose-innodb-sys-fields=0 loose-innodb-sys-foreign=0 loose-innodb-sys-foreign-cols=0 slow_query_log_file=/usr/local/webserver/mysql/mysql_slow.log long_query_time = 1 [mysqldump] quick max_allowed_packet = 32M3、初始化資料庫
[root@w3cschool,cc mysql]#/usr/local/webserver/mysql/scripts/mysql_install_db --defaults-file=/etc/my.cnf --user=mysql顯示如下資訊:
Installing MySQL system tables...2015-01-26 20:18:51 0 [Warning] TIMESTAMP with implicit DEFAULT value is deprecated. Please use --explicit_defaults_for_timestamp server option (see documentation for more details). OK Filling help tables...2015-01-26 20:18:57 0 [Warning] TIMESTAMP with implicit DEFAULT value is deprecated. Please use --explicit_defaults_for_timestamp server option (see documentation for more details). OK ...4、建立開機啟動腳本
[root@w3cschool,cc mysql]# cd /usr/local/webserver/mysql/ [root@w3cschool,cc mysql]# cp support-files/mysql.server /etc/rc.d/init.d/mysqld [root@w3cschool,cc mysql]# chkconfig --add mysqld [root@w3cschool,cc mysql]# chkconfig --level 35 mysqld on4、啟動mysql伺服器
[root@w3cschool,cc mysql]# service mysqld start5、連接MySQL
[root@w3cschool,cc mysql]# /usr/local/webserver/mysql/bin/mysql -u root -p修改MySQL使用者密碼
mysqladmin -u用户名 -p旧密码 password 新密码
或進入mysql命令列SET PASSWORD FOR '用户名'@'主机' = PASSWORD(‘密码');建立新使用者並授權:
grant all privileges on *.* to 用户名@'%' identified by '密码' with grant option;其他指令
- 啟動:service mysqld start
- 停止:service mysqld stop
- 重啟:service mysqld restart
- #重載設定:service mysqld reload
