Linux 安装多个php版本并配置

我已经安装了php7.4，现在想再安装一个7.1，则

mkdir -p  /lnmp/php71

wget https://www.php.net/distributions/php-7.1.18.tar.gz

tar -zxvf php-7.1.18.tar.gz

cd php-7.1.18

./configure --prefix=/lnmp/php71 --enable-fpm --with-mysqli --with-curl --with-pdo_mysql --with-pdo_sqlite --enable-mysqlnd --enable-mbstring --with-gd

make

make install

cp php.ini-development /lnmp/php71/lib/php.ini

重命名:

cd /lnmp/php71/etc

mv php-fpm.conf.default php-fpm.conf

mv php-fpm.d/www.conf.default php-fpm.d/www.conf

更改侦听端口(127.0.0.1:9000 为默认的)：

cd /lnmp/php71/etc/php-fpm.d

vim www.conf

 修改配置文件php.ini（vim /lnmp/php71/lib/php.ini）

cgi.fix_pathinfo=0

启动php-pfm

/lnmp/php71/sbin/php-fpm

查看是否启动成功：

ps aux|grep php

若出现以下提示，则表示安装多版本php成功

设置开机启动php

vim /etc/init.d/php71-fpm

添加以下命令行：

#!/bin/sh 
# chkconfig:   2345 15 95

[ "$NETWORKING" = "no" ] && exit 0
 
phpfpm="/lnmp/php71/sbin/php-fpm"
prog=$(basename ${phpfpm})
 
lockfile=/var/lock/subsys/phpfpm
 
start() {
    [ -x ${phpfpm} ] || exit 5
    echo -n $"Starting $prog: " 
    daemon ${phpfpm}
    retval=$?
    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
    start
}
 
reload() {
    configtest || return $?
    echo -n $"Reloading $prog: " 
    killproc ${phpfpm} -HUP
    RETVAL=$?
    echo 
}
 
force_reload() {
    restart
}
 
configtest() {
  ${phpfpm} -t
}
 
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
        ;;
    status)
        rh_status
        ;;
    *)
        echo $"Usage: $0 {start|stop|status|restart|reload|configtest}" 
        exit 2
esac

其中，phpfpm="/lnmp/php71/sbin/php-fpm"  需要改成php程序执行的路径

设置文件权限：

chmod a+x /etc/init.d/php71-fpm

加到开机启动项：

chkconfig --add php71-fpm

加入成功之后，可使用以下指令了

service php71-fpm start

service php71-fpm restart

service php71-fpm stop
