LNMP(nginx php-fpm mysql) 環(huán)境部署——mysql

發(fā)布時間:2020-10-12 14:50:00 來源:網(wǎng)絡(luò) 閱讀:1518 作者:lylspecter 欄目:數(shù)據(jù)庫

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
