mysql有二進制碼安裝，和源碼編譯安裝（mysql5.5使用cmake安裝，mysql5.7需要安裝boost依賴安裝）,因為boost依賴安裝麻煩，所以用二進制碼安裝
首先，我們可以在mysql官網下載二進制包（https://downloads.mysql.com/archives/get/p/23/file/mysql-5.7.30-linux-glibc2.12-x86_64.tar.gz）
1、 新建/usr/local/src目錄，保存下載的各類安裝包
|
1
|
mkdir /usr/local/src
|
2、切換到/usr/local/src 下
|
1
|
cd /usr/local/src
|
3、下載mysql5.7二進制包，解壓到當前目錄下
|
1
|
tar -zxvf mysql-5.7.23-linux-glibc2.5-x86_64.tar.gz
|
4.將解過的mysql5.7包移動到/usr/local/下並改名為mysql
|
1
|
mv mysql-5.7.23-linux-glibc2.5-x86_64 /usr/local/mysql
|
5.切換到/usr/local/mysql下
|
1
|
/usr/local/mysql
|
6.新增mysql用戶，並禁止shell登陸
|
1
2
|
# groupadd mysql
#useradd -r -g mysql -s /sbin/nologin mysql
|
7.初始化mysql5.7數據庫:
確認/data/mysql數據庫文件夾是否存在，不存在則創建
mkdir /data/mysql
chown -R mysql.mysql /data/mysq
初始數據庫：
|
1
|
# ./bin/mysqld --initialize --user=mysql --datadir=/data/mysql
|
a.注意：初始化數據庫后生成的臨時密碼
|
1
|
# ./bin/mysql_ssl_rsa_setup --datadir=/data/mysql
|
8.復制配置文件並修改
注意，如果./support-files/my-default.cnf 沒有這個文件，可以到網上去收一下這個文件的大致內容。

# *** DO NOT EDIT THIS FILE. It's a template which will be copied to the

[mysqld]
# Remove leading # and set to the amount of RAM for the most important data
# cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%.
# innodb_buffer_pool_size = 128M
# Remove leading # to turn on a very important data integrity option: logging
# changes to the binary log between backups.
# log_bin
# These are commonly set, remove the # and set as required.
# basedir = .....
# datadir = .....
# port = .....
# server_id = .....
# socket = .....
# Remove leading # to set options mainly useful for reporting servers.
# The server defaults are faster for transactions and fast SELECTs.
# Adjust sizes as needed, experiment to find the optimal values.
# join_buffer_size = 128M
# sort_buffer_size = 2M
# read_rnd_buffer_size = 2M
sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES
|
a.復制主配置文件
|
1
|
# cp ./support-files/my-default.cnf /etc/my.cnf
|
b.修改 /etc/my.cnf 配置文件

# vi /etc/my.cnf
# These are commonly set, remove the # and set as required.
basedir = /usr/local/mysql
//指定程序路徑
datadir = /data/mysql
//指定數據存放路徑
port = 3306
//指定端口號
# server_id = .....
socket = /tmp/mysql.sock
//指定sock文件
|
9.復制啟動文件並修改相關參數
a.復制啟動腳本文件到init.d下
|
1
|
cp ./support-files/mysql.server /etc/init.d/mysqld
|
b.修改啟動腳本相關參數
|
1

3
|
vi /etc/init.d/mysqld
basedir=/usr/local/mysql
//指定程序路徑
datadir=/data/mysql
//指定數據存放路徑
|
10.啟動mysql服務，並查看服務啟動狀態
|

|
# chkconfig --add mysqld //加入開機啟動
# /etc/init.d/mysqld start //啟動mysql服務
# ps aux |grep mysqld // 查看mysql進程
# netstat -ntlp | grep 3306 //查看3306端口監聽情況
|
11.重置密碼
a.使用初始化臨時密碼登陸
|
1
|
# /usr/local/mysql/bin/mysql -uroot -p'Ed0fem1S(oH/'
|
b.修改mysql登陸密碼:mysql
|
1
|
mysql>
set
password = password(
'mysql'
);
|
b.繼續執行
|
1
|
# ./bin/mysql_ssl_rsa_setup --datadir=/data/mysql
|
