不知道大家之前对类似使用二进制演示MySQL安装步骤的文章有无了解，今天我在这里给大家再简单的讲讲。感兴趣的话就一起来看看正文部分吧，相信看完使用二进制演示MySQL安装步骤你一定会有所收获的。

安装环境准备：

系统版本：

[root@node2 ~]# cat /etc/redhat-release

CentOS Linux release 7.4.1708 (Core)

selinux关闭：

[root@node2 ~]# getenforce

Disabled

防火墙关闭：

[root@node2 ~]# systemctl status firewalld.service

● firewalld.service - firewalld - dynamic firewall daemon

Loaded: loaded (/usr/lib/systemd/system/firewalld.service; disabled; vendor preset: enabled)

Active: inactive (dead)

Docs: man:firewalld(1)

1、安装依赖包

yum install libaio -y

2、下载MySQL二进制安装包

https://dev.mysql.com (社区网站)

https://dev.mysql.com/downloads/file/?id=474755 (下载页面)

下载地址：

wget -p /opt/  https://cdn.mysql.com//Downloads/MySQL-5.7/mysql-5.7.21-linux-glibc2.12-x86_64.tar.gz

参数说明：-p             下载所有为了html页面显示正常的文件。

-p . /local     保存所有文件和目录到本地指定目录。

3、创建用户

useradd -s /sbin/nologin -M mysql

4、解压、创建目录、并创建软连接

mkdir /opt/mysql/

tar zxf /opt/mysql-5.7.21-linux-glibc2.12-x86_64.tar.gz -C /opt/mysql/

cd /usr/local/

ln -s /opt/mysql/mysql-5.7.21-linux-glibc2.12-x86_64

5、创建数据库相关目录(备份用)

mkdir -pv /data/mysql/mysql3306/{data,logs,tmp}

6、更改相关目录的属性

chown -R mysql.mysql /usr/local/mysql

chown -R mysql.mysql /data

7、创建配置相关文件

配置文件为：/etc/my.cnf

cat > /etc/my.cnf << EOF

#my.cnf

[client]

port = 3306

socket = /tmp/mysql3306.sock

[mysql]

prompt="\u@\h [\d]>"

no-auto-rehash

[mysqld]

#misc

user = mysql

basedir = /usr/local/mysql

datadir = /data/mysql/mysql3306/data

tmpdir = /data/mysql/mysql3306/tmp

port = 3306

socket = /tmp/mysql3306.sock

event_scheduler = 0

#timeout

interactive_timeout = 300

wait_timeout = 300

#character set

character-set-server = utf8

open_files_limit = 65535

max_connections = 100

max_connect_errors = 100000

lower_case_table_names =1

gtid-mode = on

enforce-gtid-consistency=1

#rpl_semi_sync_master_enabled=1

#rpl_semi_sync_master_timeout=1000 # 1 second

#rpl_semi_sync_slave_enabled=1

####### slow log ######

log-output=file

slow_query_log = 1

slow_query_log_file = slow.log

log-error = error.log

log_warnings = 2

pid-file = mysql.pid

long_query_time = 1

#log-slow-admin-statements = 1

#log-queries-not-using-indexes = 1

log-slow-slave-statements = 1

####### binlog ######

binlog_format = row

server-id = 1003306

log-bin = /data/mysql/mysql3306/logs/mysql-bin

max_binlog_size = 256M

sync_binlog = 0

expire_logs_days = 10

#procedure

log_bin_trust_function_creators=1

####### relay log ######

skip_slave_start = 1

max_relay_log_size = 128M

relay_log_purge = 1

relay_log_recovery = 1

relay-log=relay-bin

relay-log-index = relay-bin.index

log_slave_updates = ON

#slave-skip-errors=1032,1053,1062

####### buffers & cache ######

table_open_cache = 2048

table_definition_cache = 2048

table_open_cache = 2048

tmp_table_size = 96M

key_buffer_size = 8M

read_buffer_size = 2M

read_rnd_buffer_size = 16M

bulk_insert_buffer_size = 32M

#myisam

myisam_sort_buffer_size = 128M

myisam_max_sort_file_size = 10G

myisam_repair_threads = 1

#innodb

innodb_buffer_pool_size = 100M

innodb_buffer_pool_instances = 1

innodb_data_file_path = ibdata1:100M:autoextend

innodb_flush_log_at_trx_commit = 2

innodb_log_buffer_size = 8M

innodb_log_file_size = 100M

innodb_log_files_in_group = 3

innodb_max_dirty_pages_pct = 50

innodb_file_per_table = 1

innodb_rollback_on_timeout

innodb_io_capacity = 2000

transaction_isolation = READ-COMMITTED

innodb_flush_method = O_DIRECT

EOF

8、初始化数据库

cd /usr/local/mysql/

./bin/mysqld --defaults-file=/etc/my.cnf   --initialize

9、创建启动脚本

cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld

/etc/init.d/mysqld start

Starting MySQL............ SUCCESS!   (启动成功)

10、创建快速启动的环境变量

echo "export PATH=$PATH:/usr/local/mysql/bin" >> /etc/profile

source /etc/profile

11、查看MySQL初始密码

grep "password" /data/mysql/mysql3306/data/error.log

2018-02-01T05:44:04.334666Z 1 [Note] A temporary password is generated for root@localhost: usXXw5x.zzfw(默认登录密码)

12、修改初始密码

初始密码为： q=usXXw5x.zzfw 每次初始化密码都不会相同；

登录数据库修改密码为：123456

mysql -uroot -p初始密码

mysql> alter user user() identified by '123456';

或者：

mysql> SET PASSWORD=PASSWORD('123456');

mysql> flush privileges;

说明：此处的密码更改为123456，建议密码复杂化。

或者使用下面的命令：

PASSWD=$(grep 'password is' /data/mysql/mysql3306/data/error.log  | awk '{print $NF}')

mysql -uroot -p"$PASSWD" --connect-expired-password -e "alter user user() identified by '123456';"

至此，MySQL数据库的二进制安装完成，您将进入一个暂新的数据世界。
