Linux下安裝mysql環境。

1、這裡我將mysql安裝在/usr/local/mysql目錄裡面；

mkdir /usr/local/mysql

curl -o -l

tar -xvf mysql-5.7.11-linux-glibc2.5-x86_64.tar.gz

mv mysql-5.7.11-linux-glibc2.5-x86_64/* /usr/local/mysql

5、建立data目錄

mkdir /usr/local/mysql/data

groupadd mysql

useradd -r -g mysql mysql

先進入 mysql

cd /usr/local/mysql

./bin/mysql_install_db --user=mysql --basedir=/usr/local/mysql/ --datadir=/usr/local/mysql/data/

cp -a ./support-files/my-default.cnf /etc/my.cnf

vi /etc/my.cnf

# these are commonly set, remove the # and set as required.

basedir = /usr/local/mysql
datadir = /usr/local/mysql/data
port = 3306
# server_id = .....
socket = /tmp/mysql.sock
character-set-server = utf8
# 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

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

service mysqld start

mysql5.7會生成乙個初始化密碼，在root中.mysql_secret檔案中。

[root@localhost ~]# cat /root/.mysql_secret

# password set for user 'root@localhost' at 2017-03-16 00:52:34 
ws;fmt7yh0cm

[root@localhost ~]# mysql -u root -p

alter user root@localhost identified by 'tiger';
flush privileges;

ws;fmt7yh0cm

tiger

解決方法如下

vi ~/.bash_profile

export

path=

$path

:/usr/local/mysql/bin

儲存退出

使配置檔案生效

source ~/.bash_profile
