1.下載mysql
網址： https://dev.mysql.com/downloads/mysql/
2.選擇源碼包，通用版點擊下載
直接下載就可以了，不用登錄
3.解壓編譯
tar -zxvf mysql-5.7.19.tar.gzcd mysql-5.7.19.tar.gz
創建數據目錄 mkdir -p /data/mysql
先用cmake編譯，沒有這個命令需要先yum安裝
cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql/ #這個是編譯安裝之后的mysql目錄所在地，可自行更改-DMYSQL_DATADIR=/data/mysql/ #這個指向數據目錄-DMYSQL_UNIX_ADDR=/tmp/mysql.sock-DSYSCONFDIR=/usr/local/mysql-5.7/conf/-DWITH_MYISAM_STORAGE_ENGINE=1-DWITH_INNOBASE_STORAGE_ENGINE=1-DWITH_BLACKHOLE_STORAGE_ENGINE=1-DWITH_ARCHIVE_STORAGE_ENGINE=1-DWITH_MEMORY_STORAGE_ENGINE=1-DWITH_READLINE=1-DMYSQL_TCP_PORT=3306-DENABLED_LOCAL_INFILE=1-DDEFAULT_CHARSET=utf8-DDEFAULT_COLLATION=utf8_general_ci-DMYSQL_USER=mysql-DWITH_SSL=system-DWITH_ZLIB=system -DDOWNLOAD_BOOST=1 -DWITH_BOOST=/usr/local/boost #從MySQL 5.7.5開始Boost庫是必需安裝的
編譯之后make && make install 漫長的等待....之后就安裝完成了
安裝完成之后路徑/usr/local/ 下面會有一個目錄 mysql，這個目錄就是我編譯安裝設置的路徑-
DCMAKE_INSTALL_PREFIX=/usr/local/mysql/
一般為了安全起見，我們都會創建一個mysql用戶和mysql組，執行以下命令
#添加用戶組groupadd mysql#添加用戶mysql 到用戶組mysqluseradd-g mysql mysql
給予mysql權限
chown -R mysql:mysql mysql#添加用戶組groupadd mysql#添加用戶mysql 到用戶組mysqluseradd -g mysql mysql
給予mysql權限
chown -R mysql:mysql mysql
4.接下來配置啟動向，設置開機啟動
配置/ect/my.cnf，如果沒有my.cnf可自行新建添加 , 僅供參考

接下來就執行初始化數據庫語句：
注意 mysql_install_db 已經不再推薦使用了，建議改成 mysqld –initialize 完成實例初始化。
/usr/local/mysql/bin/mysqld --initialize-insecure --user=mysql --basedir=/usr/local/mysql --datadir=/data/mysql
這步很重要，如果沒有初始化直接啟動數據庫會報錯
ERROR! The server quit without updating PID file (/data/mysql/mysql.pid).
如果初始化失敗或者報以下錯誤，就需要先清空你的/data/mysql目錄了，因為mysql目錄下面有數據所以初始化執行中止。
2017-08-29T13:39:47.241469Z 0 [ERROR] --initialize specified but the data directory has files in it. Aborting.2017-08-29T13:39:47.241536Z 0 [ERROR] Aborting
清空之后再重新初始化
/usr/local/mysql/bin/mysqld --initialize-insecure --user=mysql --basedir=/usr/local/mysql --datadir=/data/mysql
接下來可以啟動mysql了
ervice mysqld start
登錄測試
/usr/local/mysql/bin/mysql -uroot -
因為初始化--initialize-insecure 是默認沒有密碼的所以密碼不用輸入直接確定就行了；
假如登錄報錯
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)
檢查一下你啟動數據庫成功沒 可執行 ps -ef | grep mysql 看看進程是不是啟動狀態
空密碼不安全所以我們還要設置密碼，下面命令中的/"root/"就是設置密碼區域，我的密碼設置為root，可自行修改
[root@localhost local]# /usr/local/mysql/bin/mysql -e "grant all privileges on *.* to root@'127.0.0.1' identified by /"root/" with grant option;"[root@localhost local]# /usr/local/mysql/bin/mysql -e "grant all privileges on *.* to root@'localhost' identified by /"root/" with grant option;"
接下來再登錄測試一次密碼修改成功沒有就完成啦！
