CentOS7.5源碼編譯安裝mysql5.7.29

 #查看系統版本

[root@ctos3 ~]# cat /etc/redhat-release 
CentOS Linux release 7.5.1804 (Core) 

 

#下載源碼包，需要注意的是mysql5.7 編譯安裝需要boost 庫，可以在官網下載含boost的源碼包

https://dev.mysql.com/downloads/mysql/5.7.html#downloads

 

#提示，下載的時候如果不想進行登錄或注冊，就點不用，開始下載

 

#開始源碼編譯安裝

#1.安裝相關依賴包

yum install -y gcc gcc-c++ cmake ncurses ncurses-devel bison wget openssl-devel.x86_64

 

#2.創建用戶和組

groupadd  mysql
useradd mysql -s /sbin/nologin -M -g mysql

 

#3.下載mysql和解壓,也可以下載好使用rz(包名lrzsz)上傳

mkdir /home/demo/tools/
cd /home/demo/tools/
wget https://cdn.mysql.com//Downloads/MySQL-5.7/mysql-boost-5.7.29.tar.gz
tar xf mysql-boost-5.7.29.tar.gz

 

#4.配置相關參數

[root@ctos3 tools]# cd mysql-5.7.29/
[root@ctos3 mysql-5.7.29]# pwd
/home/demo/tools/mysql-5.7.29
[root@ctos3 mysql-5.7.29]# cmake -DCMAKE_INSTALL_PREFIX=/application/mysql  -DMYSQL_DATADIR=/application/mysql/data -DMYSQL_UNIX_ADDR=/application/mysql/tmp/mysql.sock -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DWITH_BOOST=boost

#參數介紹

DCMAKE_INSTALL_PREFIX  #指定MySQL程序的安裝目錄
DMYSQL_DATADIR         #數據文件目錄
DMYSQL_UNIX_ADDR       #socket文件路徑
DDEFAULT_CHARSET       #指定服務器默認字符集，默認latin1
DDEFAULT_COLLATION     #指定服務器默認的校對規則，默認latin1_general_ci

 

#5.編譯安裝

[root@ctos3 mysql-5.7.29]# make -j 2 && make install

#-j參數作用：編譯時會占用大量的系統資源，可以通過-j參數指定多個編譯命令進行並行編譯來提高速度,使用以下命令查看系統CPU核數

[root@ctos3 ~]# cat /proc/cpuinfo | grep processor |wc -l
2

 

#6.創建數據目錄和修改權限

[root@ctos3 mysql-5.7.29]# mkdir /application/mysql/data  #存放數據目錄

[root@ctos3 mysql-5.7.29]# mkdir /application/mysql/tmp   #存放sock目錄

[root@ctos3 mysql-5.7.29]# chown -R mysql.mysql /application/mysql/

 

#7.配置/etc/my.cnf文件

#注意：5.7版本沒有模板文件/application/mysql/support-files/my-default.cnf，可根據需要自行添加

[root@ctos3 ~]# cat /etc/my.cnf
[mysqld]
port = 3306
socket = /application/mysql/tmp/mysql.sock
user = mysql
basedir = /application/mysql
datadir = /application/mysql/data
pid-file = /application/mysql/data/mysql.pid
sql_mode='ONLY_FULL_GROUP_BY'
log_error = /application/mysql/mysql-error.log
!includedir /etc/my.cnf.d

[client]
port = 3306
socket = /application/mysql/tmp/mysql.sock

 

#8.初始化數據庫

[root@ctos3 support-files]# /application/mysql/bin/mysqld --initialize-insecure --user=mysql --basedir=/application/mysql --datadir=/application/mysql/data

 

 #9.生成服務啟動腳本

#設置環境變量
[root@ctos3 support-files]# echo 'export PATH=/application/mysql/bin:$PATH' >> /etc/profile
[root@ctos3 support-files]# source /etc/profile
[root@ctos3 support-files]# tail -1 /etc/profile
export PATH=/application/mysql/bin:$PATH

#生成啟動腳本
[root@ctos3 ~]# cd /application/mysql/support-files/
[root@ctos3 support-files]# ls
magic  mysqld_multi.server  mysql-log-rotate  mysql.server
[root@ctos3 support-files]# cp mysql.server /etc/init.d/mysqld

#啟動服務和設置開機自啟
[root@ctos3 support-files]# /etc/init.d/mysqld start
Starting MySQL. SUCCESS! 
[root@ctos3 support-files]# chkconfig --add mysqld
[root@ctos3 support-files]# chkconfig mysqld on

 

#10.登錄MySQL(沒有密碼登錄)

[root@ctos3 ~]# mysql -uroot -p
Enter password: 

 

#11.查看版本

mysql> select version();
+-----------+
| version() |
+-----------+
| 5.7.29    |
+-----------+
1 row in set (0.00 sec)

 

#12.設置密碼

mysql> update mysql.user set authentication_string=password('guoke123') where user='root';
Query OK, 1 row affected, 1 warning (0.01 sec)
Rows matched: 1  Changed: 1  Warnings: 1

mysql> flush privileges;
Query OK, 0 rows affected (0.01 sec)
