1.下載mysql

2.選擇源碼包，通用版點(diǎn)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.gz

cd mysql-5.7.19.tar.gz

創(chuàng)建數(shù)據(jù)目錄? mkdir -p /data/mysql

先用cmake編譯，沒有這個(gè)命令需要先yum安裝

cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql/ #這個(gè)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(gè)指向數(shù)據(jù)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(kù)是必需安裝的

編譯之后make && make install漫長(zhǎng)的等待....之后就安裝完成了

安裝完成之后路徑/usr/local/ 下面會(huì)有一個(gè)目錄 mysql，這個(gè)目錄就是我編譯安裝設(shè)置的路徑-

DCMAKE_INSTALL_PREFIX=/usr/local/mysql/

一般為了安全起見，我們都會(huì)創(chuàng)建一個(gè)mysql用戶和mysql組，執(zhí)行以下命令

#添加用戶組

groupadd mysql

#添加用戶mysql 到用戶組mysql

useradd

-g mysql mysql

給予mysql權(quán)限

chown -R mysql:mysql mysql

#添加用戶組

groupadd mysql

#添加用戶mysql 到用戶組mysql

useradd -g mysql mysql

給予mysql權(quán)限

chown -R mysql:mysql mysql

4.接下來配置啟動(dòng)向，設(shè)置開機(jī)啟動(dòng)

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(zhí)行初始化數(shù)據(jù)庫(kù)語句：

注意 mysql_install_db已經(jīng)不再推薦使用了，建議改成 mysqld –initialize 完成實(shí)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(dòng)數(shù)據(jù)庫(kù)會(huì)報(bào)錯(cuò)

ERROR! The server quit without updating PID file (/data/mysql/mysql.pid).

如果初始化失敗或者報(bào)以下錯(cuò)誤，就需要先清空你的/data/mysql目錄了，因?yàn)閙ysql目錄下面有數(shù)據(jù)所以初始化執(zhí)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(dòng)mysql了

ervice mysqld start

登錄測(cè)試

/usr/local/mysql/bin/mysql -uroot -

因?yàn)槌跏蓟?-initialize-insecure是默認(rèn)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(bào)錯(cuò)

ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)

檢查一下你啟動(dòng)數(shù)據(jù)庫(kù)成功沒? 可執(zhí)行? ps -ef | grep mysql看看進(jìn)程是不是啟動(dòng)狀態(tài)

空密碼不安全所以我們還要設(shè)置密碼，下面命令中的\"root\"就是設(shè)置密碼區(qū)域，我的密碼設(shè)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(cè)試一次密碼修改成功沒有就完成啦！
