1.安装依赖

yum -y install wget  cmake gcc gcc-c++ ncurses  ncurses-devel  libaio-devel  openssl openssl-devel

2.下载源码包

wget https://cdn.mysql.com//Downloads/MySQL-8.0/mysql-boost-8.0.11.tar.gz      (此版本带有boost)

3.创建mysql用户

groupadd mysql

useradd -r -g mysql -s /bin/false mysql

4.创建安装目录和数据目录

mkdir -p /usr/local/mysql

mkdir -p /data/mysql

5.解压源码包

tar -zxf mysql-boost-8.0.11.tar.gz -C /usr/local

6.编译&安装

需要创建 data文件夹 /usr/local/mysql/data

cd /usr/local/mysql-8.0.11

cmake . -DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DMYSQL_DATADIR=/usr/local/mysql/data -DSYSCONFDIR=/etc -DMYSQL_TCP_PORT=3306 -DWITH_BOOST=/usr/local/mysql-8.0.11/boost

make  && make install

7.配置my.cnf文件

vim /etc/my.cnf

[mysqld]

#设置3306端口

port=3306

# 设置mysql的安装目录

basedir=/usr/local/mysql

# 设置mysql数据库的数据的存放目录

datadir=/usr/local/mysql/data

# 允许最大连接

max_connections=10000

# 允许连接失败的次数。这是为了防止有人从该主机试图攻击数据库系统

max_connect_errors=10

# 服务端使用的字符集默认为UTF8

#character-set-server=utf8mb4

# 创建新表时将使用的默认存储引擎

default-storage-engine=INNODB

# 默认使用“mysql_native_password”插件认证

default_authentication_plugin=mysql_native_password

server-id=1

log-bin=mysql-bin

binlog_format=MIXED

expire_logs_days=7

wait_timeout=320

slow_query_log=1

slow_query_log_file=/usr/local/mysql/logs/mysqld-slow.log

socket=/usr/local/mysql/mysql.sock

[mysql]

# 设置mysql客户端默认字符集

default-character-set=utf8mb4

socket=/usr/local/mysql/mysql.sock

[client]

# 设置mysql客户端连接服务端时默认使用的端口

port=3306

default-character-set=utf8mb4

socket=/usr/local/mysql/mysql.sock

[mysqld_safe]

log-error=/usr/local/mysql/logs/mysql.log//需要创建文件 touch  /usr/local/mysql/logs/mysql.log

pid-file=/usr/local/mysql/pid/mysql.pid需要创建文件 touch  /usr/local/mysql/logs/mysql.pid

socket=/usr/local/mysql/mysql.sock

[mysqldump]

user=root

password=leishen2015

socket=/usr/local/mysql/mysql.sock

8.目录权限修改

chown -R mysql:mysql /usr/local/mysql

chown -R mysql:mysql /data/mysql

chmod 755 /usr/local/mysql -R

chmod 755 /data/mysql -R

9.初始化

bin/mysqld --initialize --user=mysql

10.启动mysql

/usr/local/mysql/support-files/mysql.server

11.修改账号密码

bin/mysql  -uroot -p

mysql> alter user 'root'@'localhost' identified by "123456";

##添加远程特账号

mysql> create user root@'%' identified by '123456';

mysql> grant all privileges on *.* to root@'%';

mysql> flush privileges;

12.创建软链接(非必要)

ln -s /usr/local/mysql/bin/* /usr/local/bin/

13.添加到启动(非必要)

cp support-files/mysql.server /etc/init.d/mysql.server
