安装MYSQL5.6

最近公司某个项目要用mysql5.6版本，又要整理份安装文档。真心不爱写安装文档类，贴于此。

1. 安装必要的组件

1 2	# yum install –y autoconf automake imake libxml2-devel\ expat-devel cmake gcc gcc-c++ libaio libaio-devel bzr bison libtool ncurses5-devel

2. 下载解压mysql软件

1 2 3 4 5

# cd /usr/local/src # wget -c http://dev./get/Downloads/MySQL-5.6/mysql-5.6.14-linux-glibc2.5-x86_64.tar.gz/from/http://cdn./ -O mysql-5.6.14-linux-glibc2.5-x86_64.tar.gz # tar zxvf mysql-5.6.14-linux-glibc2.5-x86_64.tar.gz –C ../ # cd /usr/local/ # ln -s mysql-5.6.14-linux-glibc2.5-x86_64 mysql

3. 创建Mysql用户组和用户，及数据库存放目录：

1 2 3 4 5 6 7

# mkdir -p /data/mysql_data_3306 # mkdir -p /data/mysql_log # mkdir -p /data/log-bin # groupadd mysql # useradd mysql -g mysql -M -s /sbin/nologin # chown -R mysql.mysql /data/mysql_data_3306 /data/mysql_log /data/log-bin # chown -R mysql.mysql /usr/local/mysql-5.6.14-linux-glibc2.5-x86_64

4. 配置文件（依具体环境）

# vi /etc/my.cnf

[mysqld] # GENERAL # user = mysql default-storage-engine = InnoDB socket = /data/mysql_data_3306/mysql.sock pid-file = /data/mysql_data_3306/mysql.pid port = 3306 # MyISAM # key_buffer_size = 1344M myisam_recover = FORCE,BACKUP # SAFETY # max_allowed_packet = 16M max_connect_errors = 1000000 skip_name_resolve # DATA STORAGE # datadir = /data/mysql_data_3306/ long_query_time = 1 # BINARY LOGGING # log-bin = /data/log-bin/mysql-bin-3306 expire-logs-days = 14 sync-binlog = 1 server-id = 1 max_binlog_size = 500M # REPLICATION # relay-log = /data/log-bin/relay-bin-3306 slave-net-timeout = 60 # CACHES AND LIMITS # tmp_table_size = 32M max_heap_table_size = 32M max_connections = 500 thread_cache_size = 50 open_files_limit = 65535 table_definition_cache = 4096 table_open_cache = 4096 # INNODB # innodb_data_file_path = ibdata1:128M;ibdata2:10M:autoextend innodb_flush_method = O_DIRECT innodb_log_files_in_group = 2 innodb_lock_wait_timeout = 50 innodb_log_file_size = 256M innodb_flush_log_at_trx_commit = 1 innodb_file_per_table = 1 innodb_thread_concurrency = 8 innodb_buffer_pool_size = 8G # LOGGING # log-error = /data/mysql_log/mysql-error-3306.log log-queries-not-using-indexes = 1 slow-query-log = 1 long_query_time = 1 slow-query-log-file = /data/mysql_log/mysql-slow-3306.log # FOR SLAVE # #binlog-format = ROW #log-slave-updates = true #gtid-mode = on #enforce-gtid-consistency = true #master-info-repository = TABLE #relay-log-info-repository = TABLE #sync-master-info = 1 #slave-parallel-workers = 2 #binlog-checksum = CRC32 #master-verify-checksum = 1 #slave-sql-verify-checksum = 1 #binlog-rows-query-log_events = 1 #report-port = 3306 #report-host = 10.1.1.10

5. 系统服务

1 2 3 4 5 6 7 8 9 10

# cp -af /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld_3306 # vi /etc/init.d/mysqld_3306 修改两处位置： basedir=/usr/local/mysql datadir=/data/mysql_data_3306 执行如下命令 # chmod 755 /etc/init.d/mysqld_3306 # chkconfig --add mysqld_3306 # chkconfig --level 345 mysqld_3306 on

 

6. 初始化数据库

1 2	# cd /usr/local/mysql # ./scripts/mysql_install_db --user=mysql --defaults-file=/etc/my.cnf

7. 启动数据库进程

1	# service mysqld_3306 start

8. 修改root密码

1 2 3 4

# /usr/local/mysql/bin/mysql -p -uroot -S /tmp/mysql.sock #这里直接回车就能进入数据库系统 Mysql> delete from mysql.user where user=''; Mysql> update mysql.user set password=PASSWORD(‘xxxxxxxx’) where user='root'; Mysql>flush privileges;
