前言:
上一篇已經(jīng)說過部署的初衷,如有不清楚的,可以看下上篇的前言或在評論區(qū)留言給我。
此篇主要介紹安裝mysql的方法,php會要用到mysql連接數(shù)據(jù)庫
準備:
mysql官網(wǎng):mysql.com
源碼目錄:/usr/local/src
mysql官方提供官方庫、源碼、二進制包三種安裝方式。此文會分別介紹官方庫、源碼包的安裝方式,對于二進制包,下載后可直接使用。
此文介紹mysql 5.6 社區(qū)版,在下載時不要選擇錯了
安裝:
使用官方庫安裝:
1 配置mysql.repo
vim /etc/yum.repos.d/mysql.repo # Enable to use MySQL 5.6 [mysql56-community] name=MySQL 5.6 Community Server baseurl=http://repo.mysql.com/yum/mysql-5.6-community/el/6/$basearch/ enabled=1 gpgcheck=1
2 創(chuàng)建mysql_pubkey.asc
可參考http://dev.mysql.com/doc/refman/5.6/en/checking-gpg-signature.html
vim mysql_pubkey.asc

3 導(dǎo)入mysql公鑰
gpg --import mysql_pubkey.asc
4 驗證簽名
gpg --keyserver keys.gnupg.net --recv-keys 5072E1F5
5 安裝mysql
如遇超時,可以先yum makecache下
yum install mysql-community-server
6 啟動mysql服務(wù)
service mysqld start
7 確認安裝
可以設(shè)置mysql root口令以及刪除空帳號等
mysql_secure_installation
源碼安裝:
安裝編譯依賴
yum install -y wget ncurses-devel
1 在官方下載mysql源碼包
wget http://dev.mysql.com/get/Downloads/MySQL-5.6/mysql-5.6.34.tar.gz
2 解壓
tar zxf mysql-5.6.34.tar.gz
3 添加mysql用戶組及用戶
groupadd mysql useradd -g mysql mysql -s /bin/false
4 創(chuàng)建數(shù)據(jù)目錄,并賦予權(quán)限
mkdir -p /data/mysql chown mysql:mysql /data/mysql
5 配置編譯參數(shù)
cd mysql-5.6.12 cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql \ -DMYSQL_UNIX_ADDR=/tmp/mysql.sock \ -DDEFAULT_CHARSET=utf8 \ -DDEFAULT_COLLATION=utf8_general_ci \ -DWITH_EXTRA_CHARSETS:STRING=utf8,gbk \ -DWITH_INNOBASE_STORAGE_ENGINE=1 \ -DWITH_READLINE=1 \ -DENABLED_LOCAL_INFILE=1 \ -DMYSQL_DATADIR=/data/mysql/ \ -DMYSQL_TCP_PORT=3306
6 編譯
make make install
7 設(shè)置mysql
cd /usr/local/mysql chown -R mysql . chgrp -R mysql . #初始化數(shù)據(jù)庫 scripts/mysql_install_db --user=mysql chown -R root . chown -R mysql data bin/mysqld_safe --user=mysql & #配置服務(wù) cp support-files/mysql.server /etc/init.d/mysqld
可在初始化數(shù)據(jù)庫時附加參數(shù)指定配置
scripts/mysql_install_db --user=mysql \ --basedir=/usr/local/mysql \ --datadir=/data/mysql
8 啟動mysql服務(wù)
service mysql start
9 默認初始化數(shù)據(jù)庫后 root 密碼為空,可通過mysql_secure_installation 配置mysql安全
bin/mysql_secure_installation
10 配置防火墻 開啟3306端口
iptables -I INPUT -p tcp --dport 3306 -j ACCEPT
注:若沒有安裝相關(guān)依賴,可能會看到類似如下錯誤。錯誤的結(jié)尾給出了各系統(tǒng)對應(yīng)的依賴包,安裝后需要清除cmake 緩存,直接刪除CMakeCache.txt 文件,重新配置編譯即可
-- Could NOT find Curses (missing: CURSES_LIBRARY CURSES_INCLUDE_PATH)
CMake Error at cmake/readline.cmake:85 (MESSAGE):
Curses library not found. Please install appropriate package,
remove CMakeCache.txt and rerun cmake.On Debian/Ubuntu, package name is libncurses5-dev, on Redhat and derivates it is ncurses-devel.
默認初始化數(shù)據(jù)庫后,需要修改my.cnf配置文件相關(guān)配置為實際值
