php-5.6.29安裝（centos6.8-minimal/nginx-1.8.1）

官方文檔

安裝：http://php.net/manual/zh/install.unix.nginx.php
配置選項：http://php.net/manual/en/configure.about.php

準備工作

1.yum安裝所需軟件包

# yum install -y gcc gcc-c++ make zlib zlib-devel pcre pcre-devel libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel libxml2 libxml2-devel glibc glibc-devel glib2 glib2-devel bzip2 bzip2-devel ncurses ncurses-devel curl curl-devel e2fsprogs e2fsprogs-devel krb5 krb5-devel openssl openssl-devel openldap openldap-devel nss_ldap openldap-clients openldap-servers

2.yum源沒有libmcrypt包，採用源碼安裝。

# cd /usr/local/src/
# wget http://ncu.dl.sourceforge.net/project/mcrypt/Libmcrypt/2.5.8/libmcrypt-2.5.8.tar.gz
# ./configure prefix=/usr/local/libmcrypt
# make && make install     
# echo$?

3.下載php源碼包，解壓

# wget http://am1.php.net/distributions/php-5.6.29.tar.bz2
# tar jxvf php-5.6.29.tar.bz2
# cd php-5.6.29

安裝過程

1.創建用戶php-fpm

# useradd -s /sbin/nologin php-fpm

2.配置編譯參數

# ./configure \
--prefix=/usr/local/php \
--with-config-file-path=/usr/local/php/etc \
--enable-fpm \
--with-fpm-user=php-fpm \
--with-fpm-group=php-fpm \
--with-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 \
--disable-ipv6 \
--with-pear \
--with-curl \
--with-openssl

3.編譯和安裝

# make && make install
# echo $?

4.修改配置文件

# cp php.ini-production /usr/local/php/etc/php.ini
# vim /usr/local/php/etc/php-fpm.conf
# /usr/local/php/sbin/php-fpm -t

php-fpm.conf修改項如下：
    [global]
    pid = /usr/local/php/var/run/php-fpm.pid
    error_log = /usr/local/php/var/log/php-fpm.log
    [www]
    listen = /tmp/php-fcgi.sock
    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
運行/usr/local/php/sbin/php-fpm -t，若結果爲“test is successful”，則配置正確。

5.拷貝php-fpm啓動腳本到/etc/init.d/，更改權限

# cp /usr/local/src/php-5.6.29/sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm
# chmod 755 /etc/init.d/php-fpm
# service php-fpm start

若使php-fpm開機啓動，運行chkconfig --add php-fpm;chkconfig php-fpm on。
查看服務是否啓動，運行ps aux | grep php。
