Linux学习笔记十二周一次课（4月23日）

12.1 LNMP架构介绍

12.2 MySQL安装

进入下载目录cd /usr/local/src

查看已下载的文件ls

查看进程是否运行ps aux | grep mysql

删除安装目录rm -rf /usr/local/mysql

删除服务rm -rf /etc/init.d/mysqld

修改配置文件vim /etc/my.cnf //不修改，保留即可；

进入下载目录cd /usr/local/src

wget http://mirrors.sohu.com/mysql/MySQL-5.6/mysql-5.6.36-linux-glibc2.5-x86_64.tar.gz

tar zxvf mysql-5.6.36-linux-glibc2.5-x86_64.tar.gz

mv mysql-5.6.36-linux-glibc2.5-x86_64 /usr/local/mysql

cd /usr/local/mysql

useradd mysql //添加用户，之前已添加过，可以查看#id mysql,清单掉#rm -rf /data/mysql/*;

mkdir /data/

./scripts/mysql_install_db --user=mysql --datadir=/data/mysql

cp support-files/my-default.cnf /etc/my.cnf //或者修改my.cnf文档，（datadir=/data/mysql,socket=/tmp/mysql.sock即可）

cp support-files/mysql.server /etc/init.d/mysqld

vim /etc/init.d/mysqld //定义basedir和datadir，(basedir=/usr/local/mysql,datadir=/data/mysql )

/etc/init.d/mysqld start

ps aux | grep mysql

chkconfig --add mysqld //添加到开机启动项

chkconfig mysqld on

service mysqld stop

service mysqld start

ps aux | grep mysql

12.3/12.4 PHP安装

cd /usr/local/src/

useradd -s /sbin/nologin php-fpm

cd php-5.6.30/

#make clean //之前编译过的文件删掉

./configure --prefix=/usr/local/php-fpm --with-config-file-path=/usr/local/php-fpm/etc --enable-fpm --with-fpm-user=php-fpm --with-fpm-group=php-fpm --with-mysql=/usr/local/mysql --with-mysqli=/usr/local/mysql/bin/mysql_config --with-pdo-mysql=/usr/local/mysql --with-mysql-sock=/tmp/mysql.sock --with-libxml-dir --with-gd --with-jpeg-dir --with-png-dir --with-freetype-dir --with-iconv-dir --with-zlib-dir --with-mcrypt --enable-soap --enable-gd-native-ttf --enable-ftp --enable-mbstring --enable-exif --with-pear --with-curl --with-openssl //少curl，安装yum install libcurl-devel -y,安装后再配置

make && make install

ls /usr/local/php-fpm/sbin/

/usr/local/php-fpm/sbin/php-fpm -m

/usr/local/php-fpm/sbin/php-fpm -i

/usr/local/php-fpm/sbin/php-fpm -t  //测试php文件语法

cp php.ini-production /usr/local/php-fpm/etc/php.ini

vi /usr/local/php/etc/php-fpm.conf //写入如下内容（参考https://coding.net/u/aminglinux/p/aminglinux-book/git/blob/master/D15Z/php-fpm.conf）

[global]

pid = /usr/local/php-fpm/var/run/php-fpm.pid

error_log = /usr/local/php-fpm/var/log/php-fpm.log

[www]

listen = /tmp/php-fcgi.sock

listen.mode = 666

user = php-fpm

group = php-fpm

pm = dynamic

pm.max_children = 50

pm.start_servers = 20

pm.min_spare_servers = 5

pm.max_spare_servers = 35

pm.max_requests = 500

  rlimit_files = 1024

写入以上内容；

cp sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm //启动脚本

chmod 755 /etc/init.d/php-fpm

chkconfig --add php-fpm

chkconfig php-fpm on

service php-fpm start

ps aux | grep php-fpm
