進入下載目錄cd /usr/local/src
查看已下載的文件ls
查看進程是否運行ps aux | grep mysql
刪除安裝目錄rm -rf /usr/local/mysql
刪除服務rm -rf /etc/init.d/mysqld
修改配置文件vim /etc/my.cnf //不修改，保留即可；
進入下載目錄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 //添加用戶，之前已添加過，可以查看#id mysql,清單掉#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文檔，（datadir=/data/mysql,socket=/tmp/mysql.sock即可）
cp support-files/mysql.server /etc/init.d/mysqld
vim /etc/init.d/mysqld //定義basedir和datadir，(basedir=/usr/local/mysql,datadir=/data/mysql )
/etc/init.d/mysqld start
ps aux | grep mysql
chkconfig --add mysqld //添加到開機啟動項
chkconfig mysqld on
service mysqld stop
service mysqld start
ps aux | grep mysql

cd /usr/local/src/
useradd -s /sbin/nologin php-fpm
cd php-5.6.30/
#make clean //之前編譯過的文件刪掉
./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，安裝yum install libcurl-devel -y,安裝後再配置
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 //測試php文件語法
cp php.ini-production /usr/local/php-fpm/etc/php.ini
vi /usr/local/php/etc/php-fpm.conf //寫入如下內容（參考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
