mysql5.7二進制安裝筆記

檢測系統(tǒng)是否已經(jīng)安裝過mysql或其依賴，若已裝過要先將其刪除，否則第4步使用yum安裝時會報錯：

[root@mysql01 Packages]# yum list installed |grep mysql
mysql-libs.x86_64 5.1.73-5.el6_6 @anaconda-CentOS-201508042137.x86_64/6.7
[root@mysql01 Packages]# yum -y remove mysql-libs.x86_64

1.創(chuàng)建安裝包存放位置
mkdir /soft

2.編輯配置文件
vim /etc/my.cnf

3.解壓二進制安裝包
tar -xzvf mysql-5.7.24-linux-glibc2.12-x86_64.tar.gz
查看依賴包：ldd bin/mysqld
root@mysql01 mysql3306]# cd /soft/mysql-5.7.24-linux-glibc2.12-x86_64
[root@mysql01 mysql-5.7.24-linux-glibc2.12-x86_64]# ls
bin COPYING docs include lib man README share support-files
[root@mysql01 mysql-5.7.24-linux-glibc2.12-x86_64]# ldd bin/mysqld
4.
mv mysql-5.7.21-linux-glibc2.12-x86_64 /usr/local/mysql
cd /usr/local/
ln -s /soft/mysql-5.7.24-linux-glibc2.12-x86_64 mysql
chown -R mysql:mysql mysql/

5.

useradd mysql
groupadd mysql
創(chuàng)建一個沒有shell的帳號
useradd -g mysql -d /usr/local/mysql -s /sbin/nologin -MN mysql
MN：代表不創(chuàng)建home目錄，不在目錄下創(chuàng)建任何隱藏文件
6.創(chuàng)建
mkdir -p /data/mysql/mysql3306/data
mkdir -p /data/mysql/mysql3306/logs
mkdir -p /data/mysql/mysql3306/tmp
chown -R mysql:mysql /data/mysql/

7.
vim /etc/my.cnf
innodb_buffer_pool_size = 512M

9.修改配置文件
vim /etc/profile
export MYSQL_HOME=/usr/local/mysql
PATH=$PATH:$MYSQL_HOME/bin

生效
source /etc/profile

10.初始化
/usr/local/mysql/bin/mysqld --defaults-file=/data/mysql/my3306.cnf --initialize-insecure --basedir=/usr/local/mysql --datadir=/data/mysql/mysql3306/data --user=mysql

12.啟動
mysqld_safe --user=mysql &
/usr/local/mysql/bin/mysqld --defaults-file=/etc/my.cnf &
/usr/local/mysql/bin/mysqld --defaults-file=/data/mysql/my3306.cnf &
登錄
mysql -S /tmp/mysql3306.cnf -p
mysql -S /data/mysql/mysql3306.sock -p
修改root密碼
mysql> SET PASSWORD = 'root123';
Query OK, 0 rows affected (0.01 sec)
設(shè)置為永不過期
mysql> ALTER USER 'root'@'localhost' PASSWORD EXPIRE NEVER;
Query OK, 0 rows affected (0.00 sec)

mysql> flush privileges;
Query OK, 0 rows affected (0.01 sec)
[root@mysql01 mysql3306]# mysql -uroot -proot123
root@mysql01 06:34: [(none)]> create database qixin;
root@mysql01 06:34: [(none)]> use qixin
root@mysql01 06:34: [qixin]> show tables;
root@mysql01 06:34: [qixin]> show databases;

多實例
mkdir -p /home/mysql3307/mysql3307

mkdir -p /home/mysql3307/logs

chown mysql.mysql -R /home/mysql3307

初始化
mysqld --defaults-file=/data/mysql/my3307.cnf --initialize-insecure --basedir=/usr/local/mysql --datadir=/data/mysql/mysql3307/data --user=mysql

啟動
mysqld_safe --defaults-file=/data/mysql/my3307.cnf --user=mysql &
mysqld --defaults-file=/data/mysql/my3306.cnf & 建議用這種
/usr/local/mysql/bin/mysqld_multi start 3306 官方已經(jīng)不在維護

/usr/local/mysql/bin/mysqld --verbose --help |grep my.cnf 可以查看配置文件加載情況
/usr/local/mysql/bin/perror 27
關(guān)庫：
mysqladmin -S /tmp/mysql3306.sock -pzstzst shutdown
mysql>shutdown;

8.0安裝
不保留原文件解壓：
xz -d mysql-8.0.17-linux-glibc2.12-x86_64.tar.xz
tar -xvf mysql-8.0.17-linux-glibc2.12-x86_64.tar
