CentOS6.5二进制文件安装MySQL5.6.39

准备工作
MySQ二进制安装Lmysql-5.6.39-linux-glibc2.12-x86_64.tar.gz准备(官网下载)

一、检查是否安装过MySQL并卸载
# 检查是否安装过MySQL
[root@csxf ~]# rpm -qa|grep mysql
# 删除所有MySQL
[root@csxf ~]# yum -y remove mysql*
二、上传镜像文件至：/usr/local，解压，移动
[root@csxf ~]# su - root

[root@csxf ~]# cd /usr/local/
[root@csxf local]# tar -xzvf mysql-5.6.39-linux-glibc2.12-x86_64.tar.gz
[root@csxf local]# mv mysql-5.6.39-linux-glibc2.12-x86_64/ mysql

三、添加MySQL用户和组赋予权限
#添加mysql用户和组
[root@csxf ~]# groupadd -g 101 dba
[root@csxf ~]# useradd -u 514 -g dba -G root -d /usr/local/mysql mysqladmin
[root@csxf ~]#id mysqladmin
#添加环境变量
[root@csxf local]# cp /etc/skel/.* /usr/local/mysql

四、配置my.cnf及修改权限
#默认配置文件所在位置 /etc/my.cnf

[client]port = 3306socket = /usr/local/mysql/data/mysql.sock[mysqld]port = 3306socket = /usr/local/mysql/data/mysql.sockskip-external-lockingkey_buffer_size = 256Msort_buffer_size = 2Mread_buffer_size = 2Mread_rnd_buffer_size = 4Mquery_cache_size= 32Mmax_allowed_packet = 16Mmyisam_sort_buffer_size=128Mtmp_table_size=32Mtable_open_cache = 512thread_cache_size = 8wait_timeout = 86400interactive_timeout = 86400max_connections = 600# Try number of CPU's*2 for thread_concurrencythread_concurrency = 32#isolation level and default enginedefault-storage-engine = INNODBtransaction-isolation = READ-COMMITTEDserver-id = 1basedir = /usr/local/mysqldatadir = /usr/local/mysql/datapid-file = /usr/local/mysql/data/hostname.pid#open performance schemalog-warningssysdate-is-nowbinlog_format = MIXEDlog_bin_trust_function_creators=1log-error = /usr/local/mysql/data/hostname.errlog-bin=/usr/local/mysql/arch/mysql-bin#other logs#general_log =1#general_log_file = /usr/local/mysql/data/general_log.err#slow_query_log=1#slow_query_log_file=/usr/local/mysql/data/slow_log.err#for replication slave#log-slave-updates#sync_binlog = 1#for innodb optionsinnodb_data_home_dir = /usr/local/mysql/data/innodb_data_file_path = ibdata1:500M:autoextendinnodb_log_group_home_dir = /usr/local/mysql/archinnodb_log_files_in_group = 2innodb_log_file_size = 200Minnodb_buffer_pool_size = 1024Minnodb_additional_mem_pool_size = 50Minnodb_log_buffer_size = 16Minnodb_lock_wait_timeout = 100#innodb_thread_concurrency = 0innodb_flush_log_at_trx_commit = 1innodb_locks_unsafe_for_binlog=1#innodb io features: add for mysql5.5.8performance_schemainnodb_read_io_threads=4innodb-write-io-threads=4innodb-io-capacity=200#purge threads change default(0) to 1 for purgeinnodb_purge_threads=1innodb_use_native_aio=on#case-sensitive file names and separate tablespaceinnodb_file_per_table = 1lower_case_table_names=1[mysqldump]quickmax_allowed_packet = 16M[mysql]no-auto-rehash[mysqlhotcopy]interactive-timeout[myisamchk]key_buffer_size = 256Msort_buffer_size = 256Mread_buffer = 2Mwrite_buffer = 2M

#修改my.cnf文件权限
[root@csxf local]# chown mysqladmin:dba /etc/my.cnf
[root@csxf local]# chmod 640 /etc/my.cnf
#修改MySQL安装目录权限
[root@csxf local]# chown -R mysqladmin:dba /usr/local/mysql
[root@csxf local]# chmod -R 755 /usr/local/mysql
#切换mysqladmin用户，准备安装
[root@csxf local]# su - mysqladmin
[mysqladmin@csxf ~]$ pwd
/usr/local/mysql
[mysqladmin@csxf ~]$ mkdir arch

五、数据库初始化
#切换MySQL用户数据库初始化
[mysqladmin@csxf ~]$ scripts/mysql_install_db --user=mysqladmin --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data
#可能出现错误
Installing MySQL system tables..../bin/mysqld: error while loading shared libraries: libaio.so.1: cannot open shared object file: No such file or directory
#缺少libaio.so 包
[root@sht-sgmhadoopnn-01 local]# yum -y install libaio
#可能出现错误
“/usr/bin/perl: bad interpreter: No such file or directory”
#缺少perl环境
[root@csxf mysql]# yum -y install perl perl-devel
[root@csxf mysql]# yum install -y perl-Data-Dumper
出现报错根据错误实际情况处理
#删除自带my.cnf文件
[mysqladmin@csxf ~]$ rm -rf my.cnf

六、MySQL服务配置
#ROOT 用户创建服务复制到init.d服务下，方便启动和停止
[root@csxf mysql]# cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysql
#赋予可执行权限
[root@csxf ~]# chmod +x /etc/init.d/mysql
#删除服务
[root@csxf ~]# chkconfig --del mysql
#添加服务
[root@csxf ~]# chkconfig --add mysql
[root@csxf ~]# chkconfig --level 345 mysql on
[root@csxf ~]# chkconfig --list mysql
mysql 0:off 1:off 2:on 3:on 4:on 5:on 6:off

六、MySQL启动服务
[root@csxf local]# su - mysqladmin
[mysqladmin@csxf ~]$ bin/mysqld_safe &
[1] 10596
180508 17:21:55 mysqld_safe Logging to '/usr/local/mysql/data/hostname.err'.
180508 17:21:55 mysqld_safe Starting mysqld daemon with databases from /usr/local/mysql/data
.....按回车键

#查看是否启动成功
[mysqladmin@csxf ~]$ ps -ef|grep mysql
root 10420 10210 0 16:52 pts/0 00:00:00 su - mysqladmin
root 10550 10519 0 17:12 pts/0 00:00:00 su - mysqladmin
514 10596 10551 0 17:21 pts/0 00:00:00 /bin/sh bin/mysqld_safe
514 11239 10596 1 17:21 pts/0 00:00:00 /usr/local/mysql/bin/mysqld --basedir=/usr/local

七、登录及基本操作

#启动数据库
service mysql start/stop/status/restart

# 首次登录
