1、編譯安裝MySQL8.0

• 　　安裝依賴包

　　yum-yinstallwgetcmakegccgcc-c++ncursesncurses-devellibaio-developensslopenssl-devel
　　rpm-qa|greplibaio
　　yuminstalllibaiolibaio-devel

• 　　下載原始碼包

  wgethttps://dev.mysql.com/get/Downloads/MySQL-8.0/mysql-boost-8.0.12.tar.gz

• 　　建立使用者和建立資料目錄並賦予使用者目錄許可權

groupaddmysql
useradd-r-gmysql-s/sbin/nologinmysql
mkdir-p/usr/local/mysql
mkdir-p/data/mysql
chown-Rmysql.mysql/usr/local/mysql
chown-Rmysql.mysql/data/mysql
chmod-R755/usr/local/mysql/
chmod-R755/data/mysql/
 

• 解壓並開始安裝

tar-zxfmysql-boost-8.0.12.tar.gz

• 配置

cdmysql-8.0.12
cmake.-DCMAKE_INSTALL_PREFIX=/usr/local/mysql\
-DMYSQL_DATADIR=/data/mysql\
-DSYSCONFDIR=/etc\
-DMYSQL_TCP_PORT=3306\
-DWITH_BOOST=~/mysql-8.0.12/boost\
-DDEFAULT_CHARSET=utf8\
-DDEFAULT_COLLATION=utf8_general_ci\
-DENABLED_LOCAL_INFILE=ON\
-DWITH_INNODB_MEMCACHED=ON\
-DWITH_INNOBASE_STORAGE_ENGINE=1\
-DWITH_FEDERATED_STORAGE_ENGINE=1\
-DWITH_BLACKHOLE_STORAGE_ENGINE=1\
-DWITH_ARCHIVE_STORAGE_ENGINE=1\
-DWITHOUT_EXAMPLE_STORAGE_ENGINE=1\
-DWITH_PERFSCHEMA_STORAGE_ENGINE=1
 

配置引數說明：

CMAKE_INSTALL_PREFIX ：指定基礎安裝目錄
MYSQL_DATADIR ：指定資料目錄
SYSCONFDIR=/etc ：指定配置檔案掃描目錄
MYSQL_TCP_PORT ：指定埠號
WITH_BOOST ：指定boost所在目錄
DEFAULT_CHARSET ：指定預設字符集
DEFAULT_COLLATION ：指定預設排序規則
ENABLED_LOCAL_INFILE=ON ：是否為load data infile啟用local
WITH_INNODB_MEMCACHED=ON:是否生成memcached共享庫

報錯GCC 4.8.3 or newer is required (-dumpversion says 4.4.7)
 

CMake Error at cmake/os/Linux.cmake:46 (MESSAGE):
GCC 4.8.3 or newer is required (-dumpversion says 4.4.7)
Call Stack (most recent call first):

• 編譯&安裝

make&&makeinstall

• 初始化資料庫

mysqld--initialize-insecure--user=mysql--basedir=/usr/local/mysql--datadir=/data/mysql

• 建立配置檔案

cat>/etc/my.cnf<<EOF
[client]
port=3306
socket=/tmp/mysql.sock
default-character-set=utf8
#user=root
#password=123
[mysqld]
server-id=1
#skip-grant-tables
port=3306
user=mysql
max_connections=200
socket=/tmp/mysql.sock
basedir=/usr/local/mysql
datadir=/data/mysql
pid-file=/data/mysql/mysql.pid
init-connect='SETNAMESutf8'
character-set-server=utf8
default-storage-engine=INNODB
log_error=/data/mysql/mysql-error.log
slow_query_log_file=/data/mysql/mysql-slow.log
[mysqldump]
quick
max_allowed_packet=16M
EOF

• 配置環境變數

echo"PATH=/usr/local/mysql/bin:$PATH">>/etc/profile
source/etc/profile

• 配置啟動指令碼

cp../mysql-8.0.12/support-files/mysql.server/etc/init.d/mysqld
vim/etc/init.d/mysqld
chmod+x/etc/init.d/mysqld
/etc/init.d/mysqldstart

• centos7系統自啟動指令碼

cat/usr/lib/systemd/system/mysqld.service
[Unit]
Description=mysqlserverdaemon
Documentation=man:mysql(8)
Documentation=http://dev.mysql.com/doc/refman/en/using-systemd.html
After=network.target
After=syslog.target
[Install]
WantedBy=multi-user.target
[Service]
User=mysql
Group=mysql
Type=notify
TimeoutSec=0
PermissionsStartOnly=true
ExecStart=/usr/local/mysql/bin/mysqld$MYSQLD_OPTS
LimitNOFILE=10000
Restart=always
RestartPreventExitStatus=1
Environment=MYSQLD_PARENT_PID=1
PrivateTmp=false

• 啟動MySQL

systemctlstartmysqld.service

• 修改root密碼：使用WITH指定認證方式

mysql-uroot
ALTERUSER'root'@'localhost'IDENTIFIEDWITHmysql_native_passwordBY'你的密碼';
ALTERUSER'root'@'localhost'IDENTIFIEDWITHcaching_sha2_passwordBY'你的密碼';

檢視密碼欄位和加密方式

selecthost,user,authentication_string,pluginfromuser;

2、yum儲存庫安裝MySQL

wgethttps://dev.mysql.com/get/mysql80-community-release-el7-1.noarch.rpm
yumlocalinstallmysql80-community-release-el7-1.noarch.rpm
yumrepolistenabled|grep"mysql.*-community.*"
yumrepolistall|grepmysql
yuminstallmysql-community-server
systemctlenablemysqld
systemctlstartmysqld
netstat-lntup|grep3306

• 檢視隨機生成的密碼

grep'temporarypassword'/var/log/mysqld.log
mysql-uroot-p

• 修改密碼,密碼必須要由大小寫字母、數字和特性字元組成

alteruser'root'@'localhost'identifiedby'[email protected]';
selectversion();
