CentOS 5.4 x86_64 編譯安裝 MySQL 完全筆記

MySQL編譯安裝筆記
大前提，你的Linux系統(tǒng)要搭建好GCC的編譯環(huán)境。
使用CentOS的話可以：
yum -y install gcc
yum -y install gcc-c++
添加MySQL用戶組和用戶
grounadd mysql
useradd -g mysql mysql
MySQL編譯安裝依賴的軟件包：
cd /tmp
-
 

wget http://ftp.gnu.org/pub/gnu/ncurses/ncurses-5.7.tar.gz
tar -zvxf ncurses-5.7.tar.gz
cd ncurses-5.7
./configure --prefix=/usr --with-shared --without-debug
make
make install

修改MySQL最大連接數(shù)，解開MySQL的原代碼，進(jìn)入里面的sql目錄修改mysqld.cc找到下面一行：
{"max_connections", OPT_MAX_CONNECTIONS,
"The number of simultaneous clients allowed.", (gptr*) &max_connections,(gptr*) &max_connections, 0, GET_ULONG, REQUIRED_ARG, 151, 1, 16384, 0, 1,0},
把它改為：
{"max_connections", OPT_MAX_CONNECTIONS,"The number of simultaneous clients allowed.", (gptr*) &max_connections,(gptr*) &max_connections, 0, GET_ULONG, REQUIRED_ARG, 1500, 1, 16384, 0, 1,0},
編譯安裝MySQL：
cd /tmp
wget http://mirrors.sohu.com/mysql/MySQL-5.5/mysql-5.5.2-m2.tar.gz
tar -zvxf mysql-5.5.2-m2.tar.gz
cd mysql-5.5.2-m2
CFLAGS="-O3" CXX=gcc CXXFLAGS="-O3 -felide-constructors -fno-exceptions -fno-rtti -fomit-frame-pointer -ffixed-ebp"
./configure --prefix=/usr/local/mysql --enable-assembler --with-charset=utf8 --with-collation=utf8_general_ci --with-extra-charsets=all --enable-thread-safe-client --with-big-tables --with-readline --with-ssl --with-embedded-server --enable-local-infile --with-client-ldflags=-all-static --with-mysqld-ldflags=-all-static --with-plugins=partition,innobase,myisammrg
make
make install
在CentOS上安裝mysql時(shí)，可能會(huì)停頓一段時(shí)間（mysql-test），多等等就過去了
安裝完成后，修改目錄權(quán)限：
chmod +w /usr/local/mysql
chown -R mysql:mysql /usr/local/mysql
建立一些必要的目錄：
mkdir -p /usr/local/mysql/data
mkdir -p /usr/local/mysql/binlog
mkdir -p /usr/local/mysql/relaylog
chown -R mysql:mysql /usr/local/mysql
使用mysql用戶帳號(hào)的身份建立數(shù)據(jù)表（www.linuxidc.com也可以說初始化mysql的數(shù)據(jù)庫）：
/usr/local/mysql/bin/mysql_install_db --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data --user=mysql
創(chuàng)建MySQL的配置文件，配置文件名通常為my.cnf：
vi /usr/local/mysql/my.cnf

創(chuàng)建管理MySQL數(shù)據(jù)庫的shell腳本：
vi /usr/local/mysql/mysql
輸入以下內(nèi)容并保存（這里的用戶名root和密碼123456接下來的步驟會(huì)創(chuàng)建）：
#!/bin/sh
mysql_port=3306
mysql_username="root"

function_start_mysql()
{
    printf "Starting MySQL...\n"
    /bin/sh /usr/local/mysql/bin/mysqld_safe --defaults-file=/usr/local/mysql/my.cnf 2>&1 > /dev/null &

function_stop_mysql()

賦予MySQL數(shù)據(jù)庫的shell腳本可執(zhí)行權(quán)限：
chmod +x /usr/local/mysql/mysql
啟動(dòng)MySQL：
/usr/local/mysql/mysql start
通過命令行登錄管理MySQL服務(wù)器（提示輸入密碼時(shí)直接回車）：
/usr/local/mysql/bin/mysql -u root -p -S /tmp/mysql.sock
輸入以下SQL語句，創(chuàng)建一個(gè)具有root權(quán)限的用戶（root）和密碼（123456）：
GRANT ALL PRIVILEGES ON *.* TO 'root'@'localhost' IDENTIFIED BY '123456';
GRANT ALL PRIVILEGES ON *.* TO 'root'@'127.0.0.1' IDENTIFIED BY '123456';
停止MySQL命令：
/usr/local/mysql/mysql stop
