[教程]centos卸載、安裝mysql（源碼編譯安裝方式）

標籤：

-----------1 卸載系統內建的msyql包 
rpm -qa|grep mysql

rpm -e --nodeps mysql-server-5.1.71-1.el6.x86_64 --強制卸載mysql安裝程式
rpm -e mysql-server-5.1.71-1.el6.x86_64 -- 有依賴關係，無法卸載

---------- 2 安裝cmake 編譯軟體 mysql5.6開始不使用configure 方式 
yum -y install cmake make

---------- 3 安裝mysql 的依賴包，其他linux 需要一個個軟體下載 編譯安裝 
yum install gcc gcc-c++ autoconf bison automake zlib* fiex* libxml* ncurses-devel libmcrypt* libtool-ltdl-devel* -y

---------- 4 建立mysql 目錄 存放日誌和資料檔案等 並更改目錄擁有者
mkdir /mysql 
mkdir /mysql/data
mkdir /mysql/logs
mkdir /mysql/data/socket
chown mysql.mysql -R /mysql

---------- 5 建立mysql使用者並不允許登入系統
groupadd mysql 
useradd mysql -g mysql -s /sbin/nologin

---------- 6 解壓（需要切換到mysql-5.6.19.tar.gz的存放目錄）
tar -zxvf mysql-5.6.19.tar.gz

---------- 7 進入mysql解壓目錄
cd mysql-5.6.19

---------- 8 編譯 
cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql \
-DMYSQL_UNIX_ADDR=/mysql/data/mysql.sock \
-DDEFAULT_CHARSET=utf8 \
-DDEFAULT_COLLATION=utf8_general_ci \
-DWITH_EXTRA_CHARSETS:STRING=utf8 \
-DWITH_INNOBASE_STORAGE_ENGINE=1 \
-DWITH_READLINE=1 \
-DENABLED_LOCAL_INFILE=1 \
-DMYSQL_DATADIR=/mysql/data/ \
-DMYSQL_USER=root \
-DMYSQL_TCP_PORT=3306

--------- 9 make 安裝 
make

--------- 10 make 安裝 
make install 

--------- 11 負載啟動命令道系統啟動目錄 
cp support-files/mysql.server /etc/init.d/mysqld
chmod 755 /etc/init.d/mysqld

--------- 12 設定為開機啟動 chkconfig --list|grep mysqld 檢測是否已經設定為開機啟動
chkconfig mysqld on

--------- 13 複製mysql命令道系統內容變數
cp /usr/local/mysql/bin/mysql /usr/bin/mysql
cp /usr/local/mysql/bin/mysql /usr/local/bin/mysql

--------- 14 初始化mysql系統資料庫 (需要回到/根目錄執行)
./usr/local/mysql/scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql --datadir=/mysql/data

 

--------- 15 mysql 修改密碼 -------------------------
> use mysql;
> UPDATE user SET password=PASSWORD(‘[email protected]#123txt‘);
> FLUSH PRIVILEGES;

--------- 16 刪除不必要的用於
> delete from user where host <> ‘localhost‘;
> update user set host=‘%‘; 
> FLUSH PRIVILEGES;
