Centos7 安装PHP

1、首先官网下载php

wget http://cn2.php.net/distributions/php-7.1.27.tar.gz

下载后，解压到服务器/usr/src目录 : tar -zxvf php-7.1.27.tar.gz

2、 添加www用户

# groupadd www

# useradd -g www www

3、完了后，configure编译，如下：

# ./configure \

--prefix=/usr/local/php \

--with-config-file-path=/usr/local/php/etc \

--enable-inline-optimization \

--disable-debug \

--disable-rpath \

--enable-shared \

--enable-opcache \

--enable-fpm \

--with-fpm-user=www \

--with-fpm-group=www \

--with-mysql=mysqlnd \

--with-mysqli=mysqlnd \

--with-pdo-mysql=mysqlnd \

--with-gettext \

--enable-mbstring \

--with-iconv \

--with-mcrypt \

--with-mhash \

--with-openssl \

--enable-bcmath \

--enable-soap \

--with-libxml-dir \

--enable-pcntl \

--enable-shmop \

--enable-sysvmsg \

--enable-sysvsem \

--enable-sysvshm \

--enable-sockets \

--with-curl \

--with-zlib \

--enable-zip \

--with-bz2 \

--with-readline

不好粘贴就复制下面的：

./configure --prefix=/usr/local/php --with-config-file-path=/usr/local/php/etc --enable-inline-optimization --disable-debug --disable-rpath --enable-shared --enable-opcache --enable-fpm --with-fpm-user=www --with-fpm-group=www --with-mysqli=mysqlnd --with-pdo-mysql=mysqlnd --with-gettext --enable-mbstring --with-iconv --with-mcrypt --with-mhash --with-openssl --enable-bcmath --enable-soap --with-libxml-dir --enable-pcntl --enable-shmop --enable-sysvmsg --enable-sysvsem --enable-sysvshm --enable-sockets --with-curl --with-zlib --enable-zip --with-bz2 --with-readline --with-gd --enable-gd-native-ttf --enable-gd-jis-conv

这个命令出现的错误直接百度就能解决。

4、安装

make

make test

make install

出现以下表示安装成功

[root@xxx bin]# ./php -version

5、 配置php-fpm 服务，自启动

cp php.ini-development /usr/local/php/etc/php.ini

设置开机启动项的步骤和原理都是一样的，这里不再累赘太多，我直接上重点。

vi /etc/init.d/php-fpm

然后加入下面的脚本：

#!/bin/sh
#
# nginx - this script starts and stops the nginx daemon
#
# chkconfig:   - 85 15
# description:  NGINX is an HTTP(S) server, HTTP(S) reverse \
#               proxy and IMAP/POP3 proxy server
# processname: nginx
# config:      /etc/nginx/nginx.conf
# config:      /etc/sysconfig/nginx
# pidfile:     /var/run/nginx.pid
# Source function library.
. /etc/rc.d/init.d/functions
# Source networking configuration.
. /etc/sysconfig/network
# Check that networking is up.
[ "$NETWORKING" = "no" ] && exit 0
nginx="/usr/sbin/nginx"
prog=$(basename $nginx)
NGINX_CONF_FILE="/etc/nginx/nginx.conf"
[ -f /etc/sysconfig/nginx ] && . /etc/sysconfig/nginx
lockfile=/var/lock/subsys/nginx
make_dirs() {
   # make required directories
   user=`$nginx -V 2>&1 | grep "configure arguments:" | sed 's/[^*]*--user=\([^ ]*\).*/\1/g' -`
   if [ -z "`grep $user /etc/passwd`" ]; then
       useradd -M -s /bin/nologin $user
   fi
   options=`$nginx -V 2>&1 | grep 'configure arguments:'`
   for opt in $options; do
       if [ `echo $opt | grep '.*-temp-path'` ]; then
           value=`echo $opt | cut -d "=" -f 2`
           if [ ! -d "$value" ]; then
               # echo "creating" $value
               mkdir -p $value && chown -R $user $value
           fi
       fi
   done
}
start() {
    [ -x $nginx ] || exit 5
    [ -f $NGINX_CONF_FILE ] || exit 6
    make_dirs
    echo -n $"Starting $prog: "
    daemon $nginx -c $NGINX_CONF_FILE
    retval=$?
    echo
    [ $retval -eq 0 ] && touch $lockfile
    return $retval
}
stop() {
    echo -n $"Stopping $prog: "
    killproc $prog -QUIT
    retval=$?
    echo
    [ $retval -eq 0 ] && rm -f $lockfile
    return $retval
}
restart() {
    configtest || return $?
    stop
    sleep 1
    start
}
reload() {
    configtest || return $?
    echo -n $"Reloading $prog: "
    killproc $nginx -HUP
    RETVAL=$?
    echo
}
force_reload() {
    restart
}
configtest() {
  $nginx -t -c $NGINX_CONF_FILE
}
rh_status() {
    status $prog
}
rh_status_q() {
    rh_status >/dev/null 2>&1
}
case "$1" in
    start)
        rh_status_q && exit 0
        $1
        ;;
    stop)
        rh_status_q || exit 0
        $1
        ;;
    restart|configtest)
        $1
        ;;
    reload)
        rh_status_q || exit 7
        $1
        ;;
    force-reload)
        force_reload
        ;;
    status)
        rh_status
        ;;
    condrestart|try-restart)
        rh_status_q || exit 0
            ;;
    *)
        echo $"Usage: $0 {start|stop|status|restart|condrestart|try-restart|reload|force-reload|configtest}"
        exit 2
esac

设置可执行权限

chmod +x php-fpm

再就是加到开机启动项里面去

chkconfig --add php-fpm

然后测试指令

service php-fpm start #开启

service php-fpm stop  #停止
