一、獲取MySQL5.7.20源碼安裝包，並上傳至服務器
MySQL官網下載地址：https://dev.mysql.com/downloads/mysql/
下載版本：mysql-boost-5.7.20.tar.gz此版本帶有boost。
二、安裝依賴包
[root@xjfw3 ~]# yum -y install gcc gcc-c++ ncurses ncurses-devel cmake三、操作系統環境和目錄結構
[root@xjfw3 ~]# cat /etc/redhat-release
Red Hat Enterprise Linux Server release 6.3 (Santiago)
[root@xjfw3 ~]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/vg_local-lv_root
20G 5.1G 14G 28% /
tmpfs 16G 76K 16G 1% /dev/shm
/dev/mapper/vg_local-lv_app
40G 176M 38G 1% /app
/dev/sda1 485M 55M 405M 12% /boot
/dev/mapper/vg_local-lv_home
4.0G 137M 3.7G 4% /home
/dev/sdb1 394G 2.8G 371G 1% /weblogic四、添加mysql禁止登錄的用戶及目錄規劃
[root@xjfw3 ~]# groupadd mysql
[root@xjfw3 ~]# useradd -r -g mysql -s /sbin/nologin mysql
MySQL數據庫目錄劃分：
mysql軟件目錄: /weblogic/mysql/mysql
mysql數據目錄：/weblogic/mysql/datadir
mysql日誌目錄：/weblogic/mysql/logdir
[root@xjfw3 ~]# mkdir -p /weblogic/mysql/mysql
[root@xjfw3 ~]# mkdir -p /weblogic/mysql/datadir
[root@xjfw3 ~]# mkdir -p /weblogic/mysql/logdi
[root@xjfw3 ~]# cd /weblogic/
[root@xjfw3 weblogic]# chown -R mysql.mysql mysql/五、解壓MySQL並編譯安裝
1、解壓Mysql
[root@xjfw3 ~]# cd /root
[root@xjfw3 ~]# ls mysql-boost-5.7.20.tar.gz
mysql-boost-5.7.20.tar.gz
[root@xjfw3 ~]# tar -xvf mysql-boost-5.7.20.tar.gz
2、編譯安裝
[root@xjfw3 ~]#
[root@xjfw3 ~]# cd /root/mysql-5.7.20/
[root@xjfw3 mysql-5.7.20]# cmake . \
> -DCMAKE_INSTALL_PREFIX=/weblogic/mysql/mysql \
> -DMYSQL_DATADIR=/weblogic/mysql/datadir \
> -DDOWNLOAD_BOOST=1 \
> -DWITH_BOOST=/root/mysql-5.7.20/boost \
> -DSYSCONFDIR=/etc \
> -DWITH_INNOBASE_STORAGE_ENGINE=1 \
> -DWITH_PARTITION_STORAGE_ENGINE=1 \
> -DWITH_FEDERATED_STORAGE_ENGINE=1 \
> -DWITH_BLACKHOLE_STORAGE_ENGINE=1 \
> -DWITH_MYISAM_STORAGE_ENGINE=1 \
> -DENABLED_LOCAL_INFILE=1 \
> -DENABLE_DTRACE=0 \
> -DDEFAULT_CHARSET=utf8 \
> -DDEFAULT_COLLATION=utf8_general_ci \
> -DWITH_EMBEDDED_SERVER=1
[root@xjfw3 mysql-5.7.20]# make & make install
（此過程時間比較長）六、配置my.cnf文件
[root@xjfw3 mysql]# vi /etc/my.cnf
[client]
port=3306
socket=/weblogic/mysql/datadir/mysql.sock
default-character-set=utf8
[mysqld]
port=3306
user=mysql
socket=/weblogic/mysql/datadir/mysql.sock
pid-file=/weblogic/mysql/datadir/mysql.pid
basedir=/weblogic/mysql/mysql
datadir=/weblogic/mysql/datadir
tmpdir=/weblogic/mysql/tmpdir
character-set-server=utf8
log_error=/weblogic/mysql/logdir/mysql.err
server-id=2
log_bin=/weblogic/mysql/logdir/binlog
general_log_file=/weblogic/mysql/logdir/general_log
general_log=1
slow_query_log=ON
long_query_time=2
slow_query_log_file=/weblogic/mysql/logdir/query_log
log_queries_not_using_indexes=ON
"/etc/my.cnf" [New] 25L, 605C written
[root@xjfw3 mysql]# 七、初始化數據庫
[root@xjfw3 datadir]# cd /weblogic/mysql/mysql/bin
[root@xjfw3 bin]# ./mysqld --initialize-insecure --user=mysql --basedir=/weblogic/mysql/mysql --datadir=/weblogic/mysql/datadir/data八、安裝ssl,可指定文件生成路徑，默認爲DATA裏面
[root@xjfw3 datadir]# cd /weblogic/mysql/mysql/bin
[root@xjfw3 bin]# ./mysql_ssl_rsa_setup

-----

[root@gsxjfw3 bin]# 九、啓動數據庫
[root@xjfw3 ~]# cp /weblogic/mysql/mysql/support-files/mysql.server /etc/init.d/msyqld
[root@xjfw3 support-files]# /etc/init.d/mysqld start
Starting MySQL.[ OK ]
[root@xjfw3 ~]# ps -ef | grep mysql
root 14979 1 0 19:57 pts/2 00:00:00 /bin/sh /weblogic/mysql/mysql/bin/mysqld_safe --datadir=/weblogic/mysql/datadir/data --pid-file=/weblogic/mysql/datadir/mysql.pid
mysql 15278 14979 0 19:57 pts/2 00:00:00 /weblogic/mysql/mysql/bin/mysqld --basedir=/weblogic/mysql/mysql --datadir=/weblogic/mysql/datadir/data --plugin-dir=/weblogic/mysql/mysql/lib/plugin --user=mysql --log-error=/weblogic/mysql/logdir/mysql.err --pid-file=/weblogic/mysql/datadir/mysql.pid --socket=/weblogic/mysql/datadir/mysql.sock --port=3306
root 15397 14855 0 20:04 pts/2 00:00:00 grep mysql
[root@xjfw3 ~]# 十、登錄數據庫並修改密碼
[root@xjfw3 ~]# /weblogic/mysql/mysql/bin/mysql

mysql> 十一、修改環境變量
[root@xjfw3 ~]# vi /etc/profile
PATH=/weblogic/mysql/mysql/bin:/weblogic/mysql/mysql/lib:$PATH
export PATH
"/etc/profile" 80L, 1868C written
[root@xjfw3 ~]# source /etc/profile
[root@xjfw3 ~]# 至此Mysql安裝完畢，源碼安裝過於繁瑣。建議使用官方編譯好的二進制文件安裝
