摘要：一安裝準(zhǔn)備官網(wǎng)下載頁二下載在下載頁，選擇的版本。創(chuàng)建用戶組和用戶設(shè)置權(quán)限的安裝目錄為初始化數(shù)據(jù)庫結(jié)果生成了一個臨時密碼，這個要記錄下來。解決編輯配置文件，然后將寫入其中。

MySQL官網(wǎng) https://www.mysql.com/

MySQL下載頁 https://dev.mysql.com/downloa...

在MySQL下載頁，選擇MySQL的版本。

選擇版本 MySQL Community Server 5.7.23

選擇 Source Code

選擇 Generic Linux (Architecture Independent)

選擇帶boost版本的 mysql-boost-5.7.23.tar.gz

復(fù)制鏈接地址

下載MySQL

yum -y install wget
wget https://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-boost-5.7.23.tar.gz

源碼方式安裝MySQL所需的環(huán)境依賴：

cmake

make

gcc

gcc-c++

bison

ncurses

ncurses-devel（devel是開發(fā)版本）

yum -y install cmake make gcc gcc-c++ bison ncurses ncurses-devel

tar -zxvf mysql-boost-5.7.23.tar.gz
cd mysql-5.7.23/

mkdir configure
cd configure

cmake .. -DWITH_BOOST=../boost/boost_1_59_0/ -DWITH_EMBEDDED_SERVER=OFF

結(jié)果：

-- Configuring done
-- Generating done
-- Build files have been written to: /root/mysql-5.7.23/configure

問題1

MySQL currently requires boost_1_59_0...

解決：因為下載的帶boost的版本，只需指定正確的 -DWITH_BOOST 參數(shù)即可，如下

-DWITH_BOOST=../boost/boost_1_59_0/

如果是不帶boost的版本，需要自己下載，并移動至解壓的mysql-5.7.23目錄下，在生成編譯文件時，指定正確的 -DWITH_BOOST 參數(shù)即可

wget https://sourceforge.net/projects/boost/files/boost/1.59.0/boost_1_59_0.tar.gz/download
tar -zxvf boost_1_59_0.tar.gz
mv boost_1_59_0 mysql-5.7.23

或者指定cmake參數(shù)，系統(tǒng)會自己下載

-DDOWNLOAD_BOOST=1 -DWITH_BOOST 

問題2

make[2]: *** [libmysqld/examples/mysql_client_test_embedded] 錯誤 1
make[1]: *** [libmysqld/examples/CMakeFiles/mysql_client_test_embedded.dir/all] 錯誤 2

解決：添加以下參數(shù)

-DWITH_EMBEDDED_SERVER=OFF

整個過程可能需要點(diǎn)時間，耐心等待。

make && make install

groupadd mysql
useradd -g mysql mysql

MySQL的安裝目錄為 /usr/local/mysql

chown -R mysql:mysql /usr/local/mysql

cd /usr/local/mysql/bin
./mysqld --initialize --user=mysql

2018-07-29T19:09:18.653886Z 1 [Note] A temporary password is generated for root@localhost: A,uNFfDrd1yd

結(jié)果：生成了一個臨時密碼，這個要記錄下來。同時有個警告

TIMESTAMP with implicit DEFAULT value is deprecated。

解決：

vim /etc/my.cnf

編輯配置文件，然后將 explicit_defaults_for_timestamp=true 寫入其中。

cd /usr/local/mysql/support-files
cp mysql.server /etc/init.d/mysql
chkconfig --add mysql # 加入系統(tǒng)服務(wù)
chkconfig mysql on # 開機(jī)啟動

service mysql start

遇到問題，如下：

Starting MySQL.2018-07-30T01:14:39.000931Z mysqld_safe error: log-error set to "/var/log/mariadb/mariadb.log", however file don"t exists. Create writable for user "mysql".
 ERROR! The server quit without updating PID file (/var/lib/mysql/localhost.localdomain.pid).

解決：創(chuàng)建該文件即可

mkdir /var/log/mariadb
touch /var/log/mariadb/mariadb.log
chown -R mysql:mysql /var/log/mariadb/mariadb.log

再次開啟mysql服務(wù)

[root@localhost support-files]# service mysql start
Starting MySQL. SUCCESS!

服務(wù)開啟成功了!

[root@localhost support-files]# mysql -u root -p
-bash: mysql: 未找到命令

創(chuàng)建軟鏈接

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

結(jié)果：

[root@localhost ~]# ll -a /usr/local/bin
總用量 0
drwxr-xr-x.  2 root root  19 7月  30 16:36 .
drwxr-xr-x. 15 root root 169 7月  30 02:58 ..
lrwxrwxrwx.  1 root root  26 7月  30 16:36 mysql -> /usr/local/mysql/bin/mysql

遇到問題

[root@localhost ~]# mysql -u root -p
Enter password:
ERROR 2002 (HY000): Can"t connect to local MySQL server through socket "/tmp/mysql.sock" (2)

解決方法

查找 mysql.sock 文件，發(fā)現(xiàn)存在于 /var/lib/mysql/ 目錄下。

[root@localhost ~]# find / -name "mysql.sock"
/var/lib/mysql/mysql.sock

再查看配置文件 my.cnf

[mysqld]
  2 datadir=/var/lib/mysql
  3 socket=/var/lib/mysql/mysql.sock
  4 explicit_defaults_for_timestamp=true

從配置文件看出socket值為 /var/lib/mysql/mysql.sock，那么可以創(chuàng)建軟鏈接到 /tmp/mysql.sock

ln -s /var/lib/mysql/mysql.sock /tmp/mysql.sock

重新登錄mysql

如果在初始化數(shù)據(jù)庫時，沒有記錄生成的臨時密碼，那就得“暴力破解”了。

首先，關(guān)閉mysql服務(wù)

service mysql stop

接著，修改/etc/my.cnf，添加skip-grant-tables，如下

[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock

skip-grant-tables

然后，免密登錄并修改登錄密碼

mysql
# 設(shè)置賬戶密碼并退出
update user set authentication_string=password("PASSWORD") where user="root";
flush privileges;

最后，將/etc/my.cnf中的skip-grant-tables刪除或注釋掉。

重啟服務(wù)，使用密碼登錄

好記性不如爛筆頭，得養(yǎng)成記錄的習(xí)慣了。
