Mysql部署

1、首先下载对应的安装包，并通过rz命令上传到linux下

2、解压该安装包

tar xzvf mysql-5.6.23-linux-glibc2.5-x86_64.tar.gz -C /usr/local/

3、将其重名

mv mysql-5.6.23-linux-glibc2.5-x86_64 mysql

4、增加用户和其相应的用户组

[root@sht-sgmhadoopnn-01 local]# groupadd -g 101 dba

[root@sht-sgmhadoopnn-01 local]# useradd -u 514 -g dba -G root -d /usr/local/mysql mysqladmin

## copy 环境变量配置文件至mysqladmin用户的home目录中,为了以下步骤配置个人环境变量

[root@sht-sgmhadoopnn-01 local]# cp /etc/skel/.* /usr/local/mysql ###important

5、修改/etc/my.cnf

mysql启动时寻找my.cnf（配置文件）

默认的找寻路径：#defualt start: /etc/my.cnf->/etc/mysql/my.cnf->SYSCONFDIR/my.cnf->$MYSQL_HOME/my.cnf-> --defaults-extra-file->~/my.cnf

my.cnf 文件内容：(

[client]
port            = 3306
socket          = /usr/local/mysql/data/mysql.sock

[mysqld]
port            = 3306
socket          = /usr/local/mysql/data/mysql.sock

skip-external-locking
key_buffer_size = 256M
sort_buffer_size = 2M
read_buffer_size = 2M
read_rnd_buffer_size = 4M
query_cache_size= 32M
max_allowed_packet = 16M
myisam_sort_buffer_size=128M
tmp_table_size=32M

table_open_cache = 512
thread_cache_size = 8
wait_timeout = 86400
interactive_timeout = 86400
max_connections = 600

# Try number of CPU's*2 for thread_concurrency
thread_concurrency = 32

#isolation level and default engine
default-storage-engine = INNODB
transaction-isolation = READ-COMMITTED

server-id = 1
basedir     = /usr/local/mysql
datadir     = /usr/local/mysql/data
pid-file     = /usr/local/mysql/data/hostname.pid

#open performance schema

#for replication slave

#for innodb options
innodb_data_home_dir = /usr/local/mysql/data/
innodb_data_file_path = ibdata1:500M:autoextend
innodb_log_group_home_dir = /usr/local/mysql/arch
innodb_log_files_in_group = 2
innodb_log_file_size = 200M

innodb_buffer_pool_size = 2048M
innodb_additional_mem_pool_size = 50M
innodb_log_buffer_size = 16M

innodb_lock_wait_timeout = 100
#innodb_thread_concurrency = 0

#purge threads change default(0) to 1 for purge

innodb_use_native_aio=on

#case-sensitive file names and separate tablespace
innodb_file_per_table = 1
lower_case_table_names=1

[mysqldump]

interactive-timeout

[myisamchk]
key_buffer_size = 256M
sort_buffer_size = 256M
read_buffer = 2M
write_buffer = 2M

)

6、修改my.cnf 所属用户和权限

[root@sht-sgmhadoopnn-01 local]# chown mysqladmin:dba /etc/my.cnf
[root@sht-sgmhadoopnn-01 local]# chmod 640 /etc/my.cnf

7、修改安装mysql那个文件夹的权限

[root@sht-sgmhadoopnn-01 local]# chown -R mysqladmin:dba /usr/local/mysql
[root@sht-sgmhadoopnn-01 local]# chmod -R 755 /usr/local/mysql

8、切换mysqladmin用户 su - mysqladmin

[mysqladmin@sht-sgmhadoopnn-01 ~]$ pwd

/usr/local/mysql

[mysqladmin@sht-sgmhadoopnn-01 ~]$ mkdir arch （创建文件夹）

9、在mysql安装目录下，执行

[mysqladmin@sht-sgmhadoopnn-01 ~]$ scripts/mysql_install_db --user=mysqladmin --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data

10、Configure mysql service and boot auto start --这里是配置开机自启动
[root@sht-sgmhadoopnn-01 ~]# cd /usr/local/mysql
#将服务文件拷贝到init.d下，并重命名为mysql
[root@sht-sgmhadoopnn-01 mysql]# cp support-files/mysql.server /etc/rc.d/init.d/mysql
#赋予可执行权限
[root@sht-sgmhadoopnn-01 mysql]# chmod +x /etc/rc.d/init.d/mysql
#删除服务
[root@sht-sgmhadoopnn-01 mysql]# chkconfig --del mysql
#添加服务
[root@sht-sgmhadoopnn-01 mysql]# chkconfig --add mysql

[root@sht-sgmhadoopnn-01 mysql]# chkconfig --level 345 mysql on

[root@sht-sgmhadoopnn-01 mysql]# vi /etc/rc.local
#!/bin/sh
#
# This script will be executed *after* all the other init scripts.
# You can put your own initialization stuff in here if you don't
# want to do the full Sys V style init stuff.

touch /var/lock/subsys/local

su - mysqladmin -c "/etc/init.d/mysql start --federated"

"/etc/rc.local" 9L, 278C written

11、Start mysql and to view process and listening

[root@sht-sgmhadoopnn-01 mysql]# su - mysqladmin
[mysqladmin@sht-sgmhadoopnn-01 ~]$ pwd
/usr/local/mysql
[mysqladmin@sht-sgmhadoopnn-01 ~]$ rm -rf my.cnf
[mysqladmin@sht-sgmhadoopnn-01 ~]$ bin/mysqld_safe &

12、查看mysql是否启动成功

ps -ef |grep mysql

netstat -nlp|grep mysql

service mysql status

13、启动mysql客户端

[mysqladmin@sht-sgmhadoopnn-01 ~]$ mysql

这样mysql就安装成功了
