mysql數據庫安裝及配置
-
安裝前的準備
yum install \ vim \ git \ gcc \ gcc-c++ \ wget \ make \ cmake \ automake \ autoconf \ libaio \ libtool \ net-tools \ bison-devel \ libaio-devel \ ncurses-devel \ perl-Data-Dumper \ -y -
下載boost_1_59_0
cd /usr/local wget http://downloads.sourceforge.net/project/boost/boost/1.59.0/boost_1_59_0.tar.gz -
下載mysql-5.7.18
cd /root wget http://dev.mysql.com/get/Downloads/MySQL-5.7/mysql-5.7.18.tar.gz tar -zxvf mysql-5.7.18.tar.gz cd mysql-5.7.18 -
運行cmake
cmake . \ -DCMAKE_INSTALL_PREFIX=/usr/local/mysql \ -DWITH_SYSTEMD=1 \ -DDOWNLOAD_BOOST=1 \ -DWITH_BOOST=/usr/local \ -DDEFAULT_CHARSET=utf8mb4 \ make make install -
添加mysql用戶
useradd -s /sbin/nologin -M mysql -
創建數據文件目錄、所屬組、用戶改爲mysql
mkdir /data/ mkdir /data/mysql/ chown -R mysql:mysql /etc/my.cnf chown -R mysql:mysql /data/mysql/ chown -R mysql:mysql /var/*/mysql* chown -R mysql:mysql /usr/local/mysql/ -
修改SELinux
vim /etc/sysconfig/selinux SELINUX=permissive ESC :wq setenforce 0 -
my.cnf詳細配置
vim /etc/my.cnf [client] default-character-set = utf8mb4 [mysql] default-character-set = utf8mb4 [mysqld] datadir=/data/mysql character-set-server=utf8mb4 init_connect='SET NAMES utf8mb4' collation-server=utf8mb4_unicode_ci character-set-client-handshake=FALSE symbolic-links=0 log-error=/var/log/mysqld.log socket=/var/lib/mysql/mysql.sock pid-file=/var/run/mysqld/mysqld.pid secure_file_priv=/var/lib/mysql-files server-id=1 binlog-format=Row log-bin=/data/mysql/mysql-bin sql-mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION ESC :wq -
初始化數據庫配置
# --initialize-insecure參數爲不安全的初始化方案，建議使用--initialize參數 # 以下代碼執行完之後,會在/data/mysql/mysql-error.log保存初始密碼 su mysql su mysql !!! su mysql !!! /usr/local/mysql/bin/mysqld \ --initialize \ --user=mysql \ --datadir=/data/mysql \ --basedir=/usr/local/mysql \ # 查看初始密碼 cat /var/lib/mysql/mysql.log|grep password # ssh連接mysql,如果對ssh不瞭解,不要這樣做 /usr/local/mysql/bin/mysql_ssl_rsa_setup \ --initialize \ --user=mysql \ vim /etc/my.cnf [client] port = 3306 socket = /tmp/mysql.sock [mysqld] port = 3306 slow_query_log = 1 long_query_time = 1 socket = /tmp/mysql.sock basedir = /usr/local/mysql datadir = /data/mysql pid-file = /data/mysql/mysql.pid log_error = /data/mysql/mysql-error.log slow_query_log_file = /data/mysql/mysql-slow.log default_storage_engine = InnoDB [mysqld_safe] log-error=/data/mysql/mysql.log pid-file=/data/mysql/mysqld.pid ESC :wq -
添加mysqld.service
exit cp /usr/local/mysql/usr/lib/systemd/system/mysqld.service /usr/lib/systemd/system/ -
mysqld.service詳細配置
vim /usr/lib/systemd/system/mysqld.service # 將下面的配置覆蓋整個文件內容 [Unit] Description=開機啓動MySQL. After=default.target network.target syslog.target [Service] User=mysql Group=mysql Type=forking PIDFile=/data/mysql/mysqld.pid TimeoutSec=0 PermissionsStartOnly=true ExecStartPre=/usr/local/mysql/bin/mysqld_pre_systemd ExecStart=/usr/local/mysql/bin/mysqld --daemonize --pid-file=/data/mysql/mysql.pid $MYSQLD_OPTS EnvironmentFile=-/etc/sysconfig/mysql LimitNOFILE = 5000 Restart=on-failure RestartPreventExitStatus=1 PrivateTmp=false [Install] WantedBy=multi-user.target ESC :wq -
啓用mysqld.service
systemctl enable mysqld systemctl start mysqld systemctl daemon-reload -
測試配置是否正確，沒有任何輸出則表示一切正常
/usr/local/mysql/bin/mysqld_pre_systemd -
數據文件所屬用戶修改爲mysql（如果‘初始化數據庫配置’時完全按文檔進行，可不執行本步驟，不確定則執行）
chown -R mysql:mysql /data/mysql/ -
啓動mysql
systemctl enable mysqld systemctl start mysqld -
添加mysql到mysql用戶環境變量
su mysql vim /home/mysql/.bash_profile PATH=$PATH:$HOME/.local/bin:$HOME/bin:/usr/local/mysql/bin ESC :wq source /home/mysql/.bash_profile -
嘗試連接mysql
# mysql默認用戶爲root mysql -u root -p password:************** #修改root[DB用戶]初始密碼 SET PASSWORD=PASSWORD('**************'); show databases; use mysql; show tables; select * from user \G; -
測試啓動、停止、重啓mysql
#啓用並啓動 systemctl enable mysqld systemctl start mysqld #禁用並關閉 systemctl disable mysqld systemctl stop mysqld #啓用並重新啓動 systemctl enable mysqld systemctl restart mysqld -
設置外部訪問密碼
