Linux CentOS MySQL 5.7.18 5.7.X安装教程
废话不多说了，直接给大家贴代码了，具体代码如下所示：
#安装依赖包 yumsearchlibaio#searchforinfo yuminstalllibaio#installlibrary #新建用户组合用户 groupaddmysql useraddmysql-gmysql #解压到data下面 tar-zxvf/data/software/mysql-5.7.18-linux-glibc2.5-x86_64.tar.gz-C/data #重命名 mvmysql-5.7.18-linux-glibc2.5-x86_64/mysql #安装 cdmysql/ mkdirdata 更改所有者 cd../ chown-Rmysql:mysqlmysql/ #授权755 chmod-R755mysql/ cdmysql ./bin/mysqld--user=mysql--basedir=/data/mysql--datadir=/data/mysql/data--initialize #注意最下面的密码 2017-04-21T02:36:14.351072Z0[Warning]TIMESTAMPwithimplicitDEFAULTvalueisdeprecated.Pleaseuse--explicit_defaults_for_timestampserveroption(seedocumentationformoredetails). 2017-04-21T02:36:15.174993Z0[Warning]InnoDB:Newlogfilescreated,LSN=45790 2017-04-21T02:36:15.331692Z0[Warning]InnoDB:Creatingforeignkeyconstraintsystemtables. 2017-04-21T02:36:15.608132Z0[Warning]NoexistingUUIDhasbeenfound,soweassumethatthisisthefirsttimethatthisserverhasbeenstarted.GeneratinganewUUID:4ab0413b-263b-11e7-9795-8e59748c97ed. 2017-04-21T02:36:15.615879Z0[Warning]Gtidtableisnotreadytobeused.Table'mysql.gtid_executed'cannotbeopened. 2017-04-21T02:36:15.620346Z1[Note]Atemporarypasswordisgeneratedforroot@localhost:o*s#gqh)F4Ck #先简单测试一下
执行./support-files/mysql.serverstart
如果提示下面错误
./support-files/mysql.server:line239:my_print_defaults:commandnotfound ./support-files/mysql.server:line259:cd:/usr/local/mysql:Nosuchfileordirectory StartingMySQLERROR!Couldn'tfindMySQLserver(/usr/local/mysql/bin/mysqld_safe)
那就正常了，哈哈
1.cpsupport-files/mysql.server /etc/init.d/mysqld
2.chmod755/etc/init.d/mysqld
3.vi/etc/init.d/mysqld
将66-73行/usr/local/修改为/data/
修改前
then basedir=/usr/local/mysql bindir=/usr/local/mysql/bin iftest-z"$datadir" then datadir=/usr/local/mysql/data fi sbindir=/usr/local/mysql/bin libexecdir=/usr/local/mysql/bin else
修改后，根据你的实际目录修改
then basedir=/data/mysql bindir=/data/mysql/bin iftest-z"$datadir" then datadir=/data/mysql/data fi sbindir=/data/mysql/bin libexecdir=/data/mysql/bin else
servicemysqldstart
如果提示StartingMySQL.Loggingto'/data/mysql/data/MyServer.err'.
不管它就行，以后重启就不会提示了
接下来来配置my.cnf
先清理一下内存
sync echo3>/proc/sys/vm/drop_caches 下面是my.cnf的具体配置 [client] no-beep socket=/data/mysql/mysql.sock #pipe #socket=0.0 port=3306 [mysql] default-character-set=utf8 [mysqld] basedir=/data/mysql datadir=/data/mysql/data port=3306 pid-file=/data/mysql/mysqld.pid #skip-grant-tables skip-name-resolve socket=/data/mysql/mysql.sock character-set-server=utf8 default-storage-engine=INNODB explicit_defaults_for_timestamp=true #ServerId. server-id=1 max_connections=2000 query_cache_size=0 table_open_cache=2000 tmp_table_size=246M thread_cache_size=300 #限定用于每个数据库线程的栈大小。默认设置足以满足大多数应用 thread_stack=192k key_buffer_size=512M read_buffer_size=4M read_rnd_buffer_size=32M innodb_data_home_dir=/data/mysql/data innodb_flush_log_at_trx_commit=0 innodb_log_buffer_size=16M innodb_buffer_pool_size=256M innodb_log_file_size=128M innodb_thread_concurrency=128 innodb_autoextend_increment=1000 innodb_buffer_pool_instances=8 innodb_concurrency_tickets=5000 innodb_old_blocks_time=1000 innodb_open_files=300 innodb_stats_on_metadata=0 innodb_file_per_table=1 innodb_checksum_algorithm=0 back_log=80 flush_time=0 join_buffer_size=128M max_allowed_packet=1024M max_connect_errors=2000 open_files_limit=4161 query_cache_type=0 sort_buffer_size=32M table_definition_cache=1400 binlog_row_event_max_size=8K sync_master_info=10000 sync_relay_log=10000 sync_relay_log_info=10000 #批量插入数据缓存大小，可以有效提高插入效率，默认为8M bulk_insert_buffer_size=64M interactive_timeout=120 wait_timeout=120 log-bin-trust-function-creators=1 sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES
修改密码
/data/mysql/bin/mysql-uroot-p
密码初装的时候有
SETPASSWORD=PASSWORD('mima123');
grantallprivilegeson*.*toroot@'%'identifiedby'mima123';
flushprivileges;
