Linux CentOS7.5上二进制安装MySQL5.7.23

1.下载二进制文件

cd /usr/local/src/
wget https://cdn.mysql.com//Downloads/MySQL-5.7/mysql-5.7.23-linux-glibc2.12-x86_64.tar.gz

2.创建MySQL组和用户

groupadd mysql
useradd -g mysql mysql
passwd mysql

3.创建安装目录、数据目录、配置目录等

mkdir -p /usr/local/mysql/
mkdir -p /usr/local/mysql/data
mkdir -p /usr/local/mysql/etc
mkdir -p /usr/local/mysql/log

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

4.安装依赖包

yum install libaio numactl

5.安装mysql

su - mysql
cd /usr/local/src/
tar -xzvf mysql-5.7.-linux-glibc2.-x86_64.tar.gz
mv /usr/local/src/mysql-5.7.-linux-glibc2.-x86_64/* /usr/local/mysql/

6.创建my.cnf配置文件

cat > /usr/local/mysql/etc/my.cnf << EOF
[client]
port =
socket=/usr/local/mysql/mysql.sock
[mysqld]
character_set_server=utf8
init_connect='SET NAMES utf8'
basedir=/usr/local/mysql
datadir=/usr/local/mysql/data
socket=/usr/local/mysql/mysql.sock
log-error=/usr/local/mysql/log/mysqld.log
pid-file=/usr/local/mysql/data/mysqld.pid
lower_case_table_names =  #不区分大小写
sql_mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION
max_connections=
default-time_zone = '+8:00'
EOF

7.初始化mysql

/usr/local/mysql/bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data
grep 'temporary password' mysqld.log   #记录默认密码

8.设置开机启动

su - root
cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld
chkconfig --add mysqld
chkconfig --list
systemctl start mysqld

9.登录数据库并修改密码

[mysql@mysql log]$ mysql -uroot -p
Enter password:
