安裝路徑：/application/mysql-5.7.18
1.前期準備
mysql依賴
libaioyum install -y libaio
創建用戶mysql，以該用戶的身份執行mysql
useradd -s /bin/false -M mysql
下載mysql二進制包并解壓
cd /toolswget https://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-5.7.18-linux-glibc2.5-x86_64.tar.gztar -zxf mysql-5.7.18-linux-glibc2.5-x86_64.tar.gz -C /application/
切換到/application目錄，將mysql文件夾名改短,給mysql目錄做一個軟鏈接
cd /application/mv mysql-5.7.18-linux-glibc2.5-x86_64/ mysql-5.7.18ln -s mysql-5.7.18/ mysql
在mysql目錄下創建mysql-files，該文件夾權限為750，遞歸設置mysql目錄的所屬組和所屬用戶
mkdir mysql/mysql-fileschmod 750 mysql/mysql-fileschown -R mysql:mysql mysql-5.7.18/
2.mysql目錄內操作
cd mysql
初始化數據庫
會在mysql目錄內生成一個data目錄，存放數據庫的目錄
bin/mysqld --initialize --user=mysql --basedir=/application/mysql --datadir=/application/mysql/data
返回結果最后一行的末尾有隨機密碼，我的記下來：wa0I:1w?V--a
2017-04-28T02:49:00.853710Z 1 [Note] A temporary password is generated for root@localhost: wa0I:1w?V--a
想設置默認密碼為空則將--initialize選項替換為--initialize-insecure選項
bin/mysqld --initialize-insecure --user=mysql --basedir=/application/mysql --datadir=/application/mysql/data
安裝ssl
bin/mysql_ssl_rsa_setup --datadir /application/mysql/data/
指定data目錄的路徑
更改所屬用戶和組
chown -R root .chown -R mysql data mysql-files
除了mysql目錄下的data目錄和mysql-files目錄所屬用戶不變，其他所有文件的所屬用戶改為root
修改配置文件
sed -i 's/^datadir=//var//lib//mysql/datadir=//application//mysql//data/g' /etc/my.cnfsed -i 's/^socket=//var//lib//mysql//mysql.sock/socket=//tmp//mysql.sock/g' /etc/my.cnfsed -i 's/^log-error=//var//log//mariadb//mariadb.log/log-error=//application//mysql//data//err.log/g' /etc/my.cnfsed -i 's/^pid-file=//var//run//mariadb//mariadb.pid/pid-file=//application//mysql//data//mysql.pid/g' /etc/my.cnf
等價于:
vi /etc/my.cnfdatadir=/application/mysql/datasocket=/tmp/mysql.socklog-error=/application/mysql/data/err.logpid-file=/application/mysql/data/mysql.pid/etc/my.cnf Content:[mysqld]datadir=/application/mysql/datasocket=/tmp/mysql.sock# Disabling symbolic-links is recommended to prevent assorted security riskssymbolic-links=0# Settings user and group are ignored when systemd is used.# If you need to run mysqld under a different user or group,# customize your systemd unit file for mariadb according to the# instructions in http://fedoraproject.org/wiki/Systemd[mysqld_safe]log-error=/application/mysql/data/err.logpid-file=/application/mysql/data/mysql.pid## include all files from the config directory#!includedir /etc/my.cnf.d
拷貝啟動程序
cp support-files/mysql.server /etc/init.d/mysql
將mysql的啟動程序拷貝到/etc/init.d/目錄下，以便啟動程序
編輯啟動文件，配置啟動目錄
方法一：
思路是給配置文件提供的變量進行賦值。較麻煩。
sed -i 's/^basedir=/basedir=//application//mysql/g' /etc/init.d/mysqlsed -i 's/^datadir=/datadir=//application//mysql//data/g' /etc/init.d/mysqlsed -i 's/^mysqld_pid_file_path=/mysqld_pid_file_path=//application//mysql//data//mysql.pid/g' /etc/init.d/mysql
等價于將45、46兩行
basedir=datadir=mysqld_pid_file_path=
替換成
basedir=/application/mysqldatadir=/application/mysql/datamysqld_pid_file_path=/application/mysql/data/mysql.pid
方法二（推薦）：
思路是將腳本的默認地址（/usr/local/mysql）直接替換成自定義路徑（/application/mysql），便不用給變量賦值
sed -i 's#/usr/local/mysql#/application/mysql#g' /etc/init.d/mysql
到這里mysql安裝完成可以正常啟動
3.后期結尾
命令創建軟鏈接
將mysql命令創建軟鏈接到環境變量的目錄，使用戶可以在變量找到相應的命令
ln -s /application/mysql/bin/* /usr/local/sbin
登錄mysql
[root@www mysql]# mysql -u root -p
Enter password: #輸入之前保存的隨機密碼drRR0
...
mysql> #成功登陸到mysql控制臺
修改密碼sql語句
mysql> alter user 'root'@'localhost' identified by 'NewPassWord';
#將密碼修改為NewPassWord
Query OK, 0 rows affected (0.01 sec) #修改成功
鍵入quit或Ctrl + d退出
mysql> quitBye[root@www mysql]#ormysql> ^DBye[root@www mysql]#
4.常用命令
進入mysql
mysql -u root -p
啟動mysql
service mysql start
停止mysql
service mysql stop
重啟mysql
service mysql restart
