centos7:mysql-5.7.23安裝（二進制安裝）

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

 

MySql 5.7.23安裝

1.首先上MySql的官網下載  https://dev.mysql.com/downloads/mysql/

選擇源碼包：

 

 

1、 新建/usr/local/src目錄，保存下載的各類安裝包

mkdir /usr/local/src

 

2、切換到/usr/local/src 下

cd /usr/local/src

 

3、下載mysql5.7二進制包，解壓到當前目錄下

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

mv mysql-5.7.23-linux-glibc2.5-x86_64 /usr/local/mysql

 

5.切換到/usr/local/mysql下

/usr/local/mysql

 

6.新增mysql用戶，並禁止shell登陸

# 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

# ./bin/mysqld --initialize --user=mysql --datadir=/data/mysql

a.注意生成的臨時密碼 Ed0fem1S(oH/

2018-08-30T02:03:43.986729Z 1 [Note] A temporary password is generated for root@localhost: Ed0fem1S(oH/

 b.繼續執行

# ./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。

# http://dev.mysql.com/doc/refman/5.7/en/server-configuration-defaults.html
# *** DO NOT EDIT THIS FILE. It's a template which will be copied to the
# *** default location during install, and will be replaced if you
# *** upgrade to a newer version of MySQL.

[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

# 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

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

 

b.修改啟動腳本相關參數

    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

# /usr/local/mysql/bin/mysql -uroot -p'Ed0fem1S(oH/'

 

b.修改mysql登陸密碼:mysql

    mysql> set password = password('mysql');
