centos6.5下的mysql5.6.30安装

1.解压mysql

tar -xf mysql-5.6.30-linux-glibc2.5-x86_64.tar.gz  -C /usr/local

mv mysql-5.6.30-linux-glibc2.5-x86_64 mysql-5.6.30

 

2.添加用户与组

groupadd mysql

useradd -g mysql mysql  -s /sbin/nologin 

chown -R mysql:mysql mysql-5.6.30

 

3.安装数据库

mkdir /usr/local/mysql-5.6.30/data3306

cd mysql-5.6.21/scripts

./mysql_install_db  --user=mysql --basedir=/usr/local/mysql-5.6.30/ --datadir=/usr/local/mysql-5.6.30/data3306/

 

4.配置文件

cd /usr/local/mysql-5.6.30/support-files

cp my-default.cnf /etc/my.cnf

cp mysql.server /etc/init.d/mysql

vim /etc/init.d/mysql

修改文件中的两个变更值

skip-external-locking

key_buffer_size = 384M

max_allowed_packet = 1073M

table_open_cache = 512

sort_buffer_size = 512K

read_buffer_size = 512K

read_rnd_buffer_size = 512K

join_buffer_size = 128K

myisam_sort_buffer_size = 64M

thread_cache_size = 256

query_cache_size = 0

query_cache_type = 0

max_heap_table_size = 64M

 

basedir=/usr/local/mysql-5.6.30/

datadir=/usr/local/mysql-5.6.30/data3306

 

pid-file = /usr/local/mysql-5.6.30/data3306/mysql.pid

log_error = /var/log/mysqld.log

 

# set binary logging is required for replication

log-bin=mysql-bin

binlog_cache_size = 32M

 

# event_scheduler shutoff in mysqld slave

event_scheduler = 1

binlog_format=row

expire_logs_days = 3

 

# set slow log

slow_query_log = 1

# set innodb params

 

innodb_data_home_dir = /usr/local/mysql-5.6.30/data3306

innodb_data_file_path = ibdata1:2000M;ibdata2:10M:autoextend

innodb_log_group_home_dir = /usr/local/mysql-5.6.30/data3306

innodb_buffer_pool_size = 5972M

innodb_additional_mem_pool_size = 10M

innodb_log_file_size = 512M

innodb_log_buffer_size = 16M

innodb_flush_method = O_DIRECT

innodb_file_per_table = 1

5.配置环境变量

vi /etc/profile

export MYSQL_HOME="/usr/local/mysql-5.6.30"

export PATH="$PATH:$MYSQL_HOME/bin"

 

6.添加自启动服务
