2、安裝步驟
解壓：
groupadd mysql useradd -r -g mysql -s /bin/false mysql cd /usr/local tar zxvf /path/to/mysql-VERSION-OS.tar.gz mv full-path-to-mysql-VERSION-OS mysql chown -R mysql mysql/ chgrp -R mysql mysql/ cd mysql mkdir mysql-files chown mysql:mysql mysql-files chmod 750 mysql-files
創建配置文件：
#先安裝一下這個，要不然初始化有可能會報錯
yum install libaio
my.cnf配置：
#創建配置文件，內容如下，可以添加你需要的配置：
vim /etc/my.cnf # For advice on how to change settings please see # http://dev.mysql.com/doc/refman/5.7/en/server-configuration-defaults.html [mysqld] # # Remove leading # and set to the amount of RAM for the most important data # cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%. # innodb_buffer_pool_size = 128M # # Remove leading # to turn on a very important data integrity option: logging # changes to the binary log between backups. # log_bin # # Remove leading # to set options mainly useful for reporting servers. # The server defaults are faster for transactions and fast SELECTs. # Adjust sizes as needed, experiment to find the optimal values. # join_buffer_size = 128M # sort_buffer_size = 2M # read_rnd_buffer_size = 2M port=3309 datadir=/data/mysql socket=/data/mysql/mysql.sock skip-name-resolve #skip-grant-tables max_connections=1000 character_set_server = utf8 wait_timeout=31536000 interactive_timeout=31536000 collation-server=utf8_general_ci lower_case_table_names=1 # Disabling symbolic-links is recommended to prevent assorted security risks symbolic-links=0 log-error=/data/log/mysqld.log pid-file=/var/run/mysqld/mysqld.pid [client] socket=/data/mysql/mysql.sock default-character-set = utf8 [mysql] default-character-set = utf8 [mysql.server] default-character-set = utf8 [mysqld_safe] default-character-set = utf8 #保存內容,按esc輸入如下命令 :wq
初始化數據庫：
mkdir /data/log chown -R mysql:mysql /data cd /var/run/ mkdir mysqld chmod 777 mysqld cd mysqld vim mysqld.pid chmod 777 mysqld.pid chown mysql:mysql mysqld.pid /usr/local/mysql/bin/mysqld --initialize --user=mysql
查看初始密碼：
cat /data/log/mysqld.log
#執行后關注最后一點：root@localhost: 這里就是初始密碼
啟動服務，進入mysql，修改初始密碼，運行遠程連接（這里執行完后，密碼將變成：123456）
/usr/local/mysql/support-files/mysql.server start #vim /etc/mysql/my.cnf #在[mysqld]項下添加 #skip-grant-tables #service mysqld restart cd /usr/local/mysql/bin ./mysql -uroot -p 執行后輸入初始密碼 alter user 'root'@'localhost' identified by '123456'; flush privileges; use mysql; #設置遠程登錄 GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '123456' WITH GRANT OPTION; flush privileges;
開機自啟：
cd /usr/local/mysql/ cp support-files/mysql.server /etc/init.d/mysqld chkconfig --add mysqld 8、使用service mysqld命令啟動/停止服務 service mysqld start/stop/restart
防火牆開開放3309端口：
vim /etc/sysconfig/iptables
service iptables restart
service mysqld restart
配置全局環境變量：
vi /etc/profile PATH=/usr/local/mysql/bin:/usr/local/mysql/lib:$PATH export PATH 設置環境變量立即生效 # source /etc/profile
查看安裝路徑：
find / -name mysql
