--prefix/usr/local/mysql_slave --enable-assembler --with-charsetutf8 --with-extra-charsetsall --enable-thread-safe-client --with-big-tables --with-readline --with-embedded-server --with-ssl -enable-local-infile $ make make install $ cd .. $ mkdir /usr/local/mysql_slave/var $ chown -R mysql:mysql /usr/local/mysql_slave/var $ chgrp -R mysql /usr/local/mysql_slave#发现/usr/local/mysql_slave/var/下的mysql和test的组均为root修改其属组 $ chgrp -R mysql /usr/local/mysql_slave#修改my.cnf位置 $ cp /usr/local/mysql_slave/share/mysql/my-medium.cnf /etc/my-slave.cnf $ vi /etc/my-slave.cnf $ :s/3306/3308/g $ :s/tmp\/mysql.sock/tmp\/mysql-slave.sock/g $ /usr/local/mysql_slave/bin/mysqld_safe --defaults-file/etc/my-slave.cnf --usermysql $ /usr/local/mysql_slave/bin/mysqladmin -uroot password 123456 配置主从库#创建mysql日志目录 $ mkdir /var/log/mysql $ chown -R mysql:mysql /var/log/mysql [vi /etc/my.cnf] server-id1 log_bin/var/log/mysql/mysql-bin.log binlog_do_dbtest binlog_ignore_dbmysql [vi /etc/my-slave.cnf] server-id2 master-host127.0.0.1 master-userslave_usr master-password123456 master-port3306 replicate-do-dbtest#启动测试 $ /etc/init.d/mysql start $ mysql -uroot -p123456 mysql grant replication slave on *.* to slave_usr127.0.0.1 identified by 123456; mysql exit; $ $ /usr/local/mysql_slave/bin/mysqld_safe --defaults-file/etc/my-slave.cnf --usermysql $ #进入主库创建表$ mysql -uroot -p123456 mysql use test; mysql create table test(id int primary key auto_increment, introtext text); mysql exit; $ mysql -uroot -p123456 -P3308 -h127.0.0.1 mysql use test; mysql desc test; 我们会发现从库里创建了一个和主库一样的表。成功但是还有以下几个问题 1.把/usr/local/mysql_slave/share/mysql/mysql.server拷贝到/etc/init.d/mysql-slave但是无法用/etc/init.d/mysql-slave start启动从库。我改了pid,socket,datadir,basedir启动也加了--defaults-file但是没有成功还要继续检查。 2.登录从库时必须加-h127.0.0.1不知道怎么去掉这个选项。 CentOS Nginx PHP MySQL 环境搭建 一、软件环境CentOS 5.4 : Nginx 0.8 : http://nginx.org/download/nginx-0.8.35.tar.gzPHP 5.2.10 : http://www.eduicc.com/soft/php-5.2.10.tar.gzMySQL 5.4.15 : http://dev.mysql.com/get/Downloads/MySQL-5.1/mysql-5.1.45.tar.gz/from/http://mysql.ntu.edu.tw/ 二、安装 1. 准备工作 这一步我称它为“准备工作”其实是安装一些系统编译及其他环境yum -y install patch make gcc gcc-c gcc-g77 flex bison

mysql-5.1.54.tar.gz cd mysql-5.1.54 ./configure --prefix/usr/local/mysql --enable-assembler --with-charsetutf8 --enable-thread-safe-client --with-extra-charsetsall --with-big-tables --with-readline --with-ssl --with-embedded-server --enable-local-infile make make install cd .. #添加mysql用户和用户组 groupadd mysql useradd -g mysql mysql cp /usr/local/mysql/share/mysql/my-medium.cnf /etc/my.cnf /usr/local/mysql/bin/mysql_install_db --usermysql chown -R mysql /usr/local/mysql/var chgrp -R mysql /usr/local/mysql/.#设置mysql开机自启动 cp /usr/local/mysql/share/mysql/mysql.server /etc/init.d/mysql chmod 755 /etc/init.d/mysql chkconfig --level 345 mysql on#增加mysql动态链接库文件 echo /usr/local/mysql/lib/mysql /etc/ld.so.conf echo /usr/local/lib /etc/ld.so.conf ldconfig ln -s /usr/local/mysql/lib/mysql

/etc/init.d/mysql stop#去掉mysql集群服务 chkconfig mysql-ndb off chkconfig mysql-ndb-mgm off 3. 安装PHP#我们用php-fpm来管理fastcgi wget http://www.eduicc.com/soft/php-5.2.10-fpm-0.5.11.diff.gz tar -zxvf php-5.2.10.tar.gz gzip -cd php-5.2.10-fpm-0.5.11.diff.gz | patch -d php-5.2.10 -p1! 这里我们要先将autoconf降低版本否则可能会出现 buildconf: Your version of autoconf likely contains buggy cache code. yum -y install autoconf213 export PHP_AUTOCONF/usr/bin/autoconf2.13 cd php-5.2.10 ./buildconf --force ./configure --prefix/usr/local/php --with-config-file-path/usr/local/php/etc --with-mysql/usr/local/mysql --with-mysqli/usr/local/mysql/bin/mysql_config --with-iconv-dir/usr/local --with-freetype-dir --with-jpeg-dir --with-png-dir --with-zlib --with-libxml-dir/usr --enable-xml --disable-rpath --enable-discard-path --enable-safe-mode --enable-bcmath --enable-shmop --enable-sysvsem --enable-inline-optimization --with-curl --with-curlwrappers --enable-mbregex --enable-fastcgi --enable-fpm --enable-force-cgi-redirect --enable-mbstring --with-mcrypt --with-gd --enable-gd-native-ttf --with-openssl --with-mhash --enable-pcntl --enable-sockets --with-xmlrpc --enable-zip --enable-ftp --without-pear make ZEND_EXTRA_LIBS-libiconv make install cp php.ini-dist /usr/local/php/etc/ 4. 安装nginx#安装pcre (Perl Compatible Regular Expressions正则表达式库) wget http://www.eduicc.com/soft/pcre-7.9.tar.gz tar -zxvf pcre-7.9.tar.gz cd pcre-7.9 ./configure make make install cd .. tar -zxvf nginx-0.8.35.tar.gz cd nginx-0.8.35 ./configure --userwww --groupwww --prefix/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module make make install#有关nginx.conf和php-fpm.conf的配置可以参照nginx.conf 和 php-fpm.conf 5. 测试 我们先来写一个脚本vi /etc/init.d/run 写入以下内容 ulimit -SHn 51200 /usr/local/php/sbin/php-fpm start /usr/local/nginx/sbin/nginx 启动测试chown 0755 /etc/init.d/run /etc/init.d/run /etc/init.d/mysql start 好了在/var/www/localhost下写个phpinfo测试下吧
